1.1 ! root 1: dmsdos driver: kernel messages in alphabetical order. ! 2: ! 3: *** Some messages need a better explanation. Under construction :) *** ! 4: ! 5: Classes: I: Information. ! 6: E: Error in filesystem, check it under dos (incl. the surface test). ! 7: O: Other problem, not a filesystem error. ! 8: B: Bug, please send a bug report. ! 9: P: Panic message. Extremely severe filesystem, hardware or dmsdos ! 10: error. The process that actually called dmsdos when the problem ! 11: occured has been "frozen" in order to prevent data corruption. ! 12: Though your system continues to run, you should reboot immediately ! 13: and check the compressed filesystems. You may have to press the ! 14: reset button in order to reboot. ! 15: ?: Unknown. (Look at the source code.) ! 16: ! 17: ------------------------------------------------------------------------------ ! 18: ! 19: DMSDOS: adapting free sectors count ! 20: I: Stacker sector count is corrected. ! 21: ! 22: DMSDOS: BB_ClustCnt=0x%x impossible (FAT32?) ! 23: E/O?: The filesystem is in an unsupported format, damaged or otherwise ! 24: strange. Dmsdos refuses to mount it. Please verify whether it is FAT32 ! 25: under Dos/Win95. Currently compressed FAT32 is not supported. ! 26: (Compressed FAT32 has never been reported to exist so far.) ! 27: ! 28: DMSDOS: bitfat cache: ! 29: I: Debug message. Ignore. ! 30: ! 31: DMSDOS: BITFAT mismatches MDFAT, repairing... ! 32: DMSDOS: BITFAT mismatches MDFAT (sector %d is %d and should be %d) ! 33: DMSDOS: BITFAT mismatches MDFAT (sector %d) ! 34: E: There's an error in the allocation table (BITFAT) of your compressed ! 35: partition - next time you boot dos you should check it. WARNING: ! 36: Writing to an errorneous filesystem may cause further damage. ! 37: Optionally (with mount option bitfaterrs=repair) ! 38: the driver tries to repair the problem by recalculating the BITFAT. ! 39: ! 40: DMSDOS: bmap called, unsupported! ! 41: B: Shouldn't happen. ! 42: ! 43: DMSDOS: cannot write dirty cluster %d on dev 0x%x, trying again later ! 44: E/O: Very likely the filesystem is full. There should be another message ! 45: describing more details. The driver keeps the cluster in memory. This ! 46: is a very critical condition as you may lose the data in that cluster. ! 47: The driver usually tries 5 times to write the data again before ! 48: throwing them away and setting the filesystem to read-only mode. If ! 49: the filesystem is really full you still have a chance to free up some ! 50: space now. ! 51: ! 52: DMSDOS: ccache contents: ! 53: DMSDOS: ccache statistics: ! 54: I: Debug messages. Ignore. ! 55: ! 56: DMSDOS: ch_dirty(_locked): READ-ONLY filesystem ! 57: O: When the filesystem suddenly is set read-only (e.g. because of a ! 58: problem) some kernel functions seem not to obey the RO flag. In this ! 59: case, the dmsdos driver itself rejects the command in order to ! 60: avoid trashing the filesystem. ! 61: ! 62: DMSDOS: ch_read: no memory! ! 63: O: System memory is even too low for read access. See below for hints ! 64: about 'no memory' messages. ! 65: ! 66: DMSDOS: ch_read: read_cluster failed ! 67: E: The cluster could not be read from disk. There should be another ! 68: message describing more details. ! 69: ! 70: DMSDOS: check_free_sectors: wrong count %d corrected to %d ! 71: B: Looks like a minor bug. As the message tells, the problem is corrected. ! 72: ! 73: DMSDOS: clear_list_dev: Uhh, sb==NULL ... ! 74: B: Shouldn't happen. ! 75: ! 76: DMSDOS: cluster %d read error ! 77: E: There should be another message describing the error more exactly. ! 78: ! 79: DMSDOS: compression method not recognized. ! 80: E: Check filesystem. May also be caused by running incompatible/unsupported ! 81: or not yet fully supported compression software under dos. In detail, the ! 82: driver found a compressed cluster but didn't recognize the compression ! 83: header. This may even be suspicious to be a dmsdos bug. ! 84: ! 85: DMSDOS: could not find MDR signature or found more than one, mdrc=%d (ignored) ! 86: I: Debug message. It may indicate a problem with the CVF, but as this ! 87: signature is almost completely unimportant, you can most likely ignore ! 88: it. ! 89: ! 90: DMSDOS: could not guess compression method for CVF ! 91: I: There's no compressed file in your compressed filesystem that dmsdos ! 92: could analyse to determine the compression method. To avoid problems, ! 93: dmsdos has disabled compression when writing to this CVF. Specify a ! 94: compression method explicitely when mounting (comp=xxx option) or write ! 95: something (more than 1KB) to the compressed partition under dos. ! 96: ! 97: DMSDOS: counted free sectors=%d ! 98: I: The message tells how many free sectors have been counted in the CVF. ! 99: ! 100: DMSDOS: CVF almost full or highly fragmented at MDFAT level. ! 101: I: The driver warns that further write access might become dangerous. ! 102: ! 103: This indicates a really bad situation. The algorithm to find free space ! 104: in a CVF performs three trials to find an appropriate hole for new data. ! 105: All of them use different priorities to avoid MDFAT level fragmentation. ! 106: But this time it did not succeed until its last trial. That means ! 107: additional MDFAT level fragmentation cannot be avoided any longer and the ! 108: more write access you perform the more likely the last trial is to fail. ! 109: ! 110: Watch the free space on the compressed partition. If there seems to be ! 111: enough, try to defragment the partition as described in chapter ! 112: 'defragment procedures' in file dmsdos.doc. ! 113: ! 114: This message has KERN_EMERG priority to ensure you can see it on the ! 115: screen. ! 116: ! 117: DMSDOS: CVF end padding %d sectors. ! 118: I: Size of STACVOL is stored in its header. If real file is ! 119: longer than this information, user is informed about that ! 120: unused sectors. It can happens when you copy stacvol ! 121: to other host drive. ! 122: ! 123: DMSDOS CVF-FAT extension version %d.%d.%d ! 124: I: Tells version number and compile-time options when loading dmsdos. ! 125: The term 'read-only' means that you are using a read-only dmsdos ! 126: version (write access has been turned off during dmsdos configuration). ! 127: It does *not* tell that the filesystem is mounted read-only or ! 128: read-write. ! 129: ! 130: DMSDOS: CVF full. ! 131: DMSDOS: CVF full (cannot even allocate fragmented space) ! 132: DMSDOS: CVF full or too fragmented at MDFAT level. ! 133: O/E: The message tells it all. The last write access may have failed and ! 134: data may have been lost. As you cannot tell how well the data will ! 135: compress it is dangerous to fill a CVF up to the last byte. There might ! 136: even be some errors in the filesystem now (but that's very unlikely). ! 137: ! 138: These messages have KERN_EMERG priority. They indicate that something ! 139: dangerous has happened. The next time you boot dos you'd better check ! 140: the filesystem. And, of course, free up some space. ! 141: ! 142: DMSDOS: CVF has bitfat mismatches, ignored. ! 143: DMSDOS: CVF has bitfat mismatches, setting to read-only. ! 144: DMSDOS: CVF has serious errors or compatibility problems, setting to read-only. ! 145: I: The driver has detected an error in the filesystem and has either ! 146: ignored the error or set the filesystem to read-only mode. There should ! 147: be another message describing the error. In rare cases, the error may ! 148: be caused by compatibility problems. ! 149: ! 150: DMSDOS: CVF has FAT32 signature, not mounted. Please report this. ! 151: O: Compressed FAT32 is unsupported. I've never seen it, but I may start ! 152: to write support for it if someone reports that a strange M$ product ! 153: really creates compressed FAT32 filesystems. I don't believe so. ! 154: ! 155: DMSDOS: CVF is in doublespace format (version 1). ! 156: DMSDOS: CVF is in drivespace 3 format. ! 157: DMSDOS: CVF is in drivespace format (version 2). ! 158: DMSDOS: CVF is in stacker 3 format. ! 159: DMSDOS: CVF is in stacker 4 format. ! 160: I: The driver reports what it has detected. ! 161: ! 162: DMSDOS: CVF is in unknown (new?) format, please report. ! 163: I: The driver didn't recognize the CVF format after verifying that it is ! 164: indeed a CVF. Watch for further messages. You'd better not write to ! 165: the partition :) ! 166: ! 167: DMSDOS: CVF is shorter about %d sectors. Mounting READ ONLY. ! 168: E: Error in stacker filesystem. Check under dos. ! 169: Real length of STACVOL is smaller, than that stored in stacvol ! 170: header. Stacvol is probably corrupted. ! 171: ! 172: DMSDOS: CVF on device 0x%x unmounted. ! 173: I: The message tells it all. ! 174: ! 175: DMSDOS: CVF set to read-only. ! 176: I: The message tells it all. ! 177: ! 178: DMSDOS: daemon is lying about its pid ! 179: O/B: Either someone is trying to compromise system security by misusing ! 180: dmsdos ioctls (without success) or the external daemon has a bug. ! 181: ! 182: DMSDOS: daemon_write_cluster: ch==NULL ! 183: B: Shouldn't happen. ! 184: ! 185: DMSDOS: Data are not SQ compressed ! 186: E: Error in drivespace 3 filesystem (invalid data?), check under Win95. ! 187: ! 188: DMSDOS: dataend corrected due to MDR signature old=%d new=%d ! 189: I: Due to a problem with the loopback block device - it only gives size ! 190: information in units of 1K blocks and not in 512 byte sectors - dmsdos ! 191: cannot determine the exact end of the CVF. So, it tries to guess where ! 192: the real end of the compressed partition is. This guess is verified by ! 193: searching the MDR signature, which is typically located in the last ! 194: sector of the CVF. If the driver has guessed the wrong end, this is ! 195: automatically corrected and this message is logged. In theory, maximum ! 196: error can be 1 sector. ! 197: ! 198: DMSDOS: dbl_bitfat_value: version not found?? cannot happen ! 199: DMSDOS: dbl_mdfat_value: unknown version?? This is a bug. ! 200: B: Shouldn't happen. ! 201: ! 202: DMSDOS: dbl_replace_existing_cluster: checking old fraglist: first fragment wrong in cluster %d ! 203: E: Filesystem error in drivespace 3 volume. Check under Win95. ! 204: ! 205: DMSDOS: dbl_replace_existing_cluster: This is a bug - reboot and check filesystem ! 206: B: Uhh. Cut'n'paste your logfile and mail it to me. This is a serious bug. ! 207: ! 208: DMSDOS: dblspace_fat_access: READ-ONLY filesystem ! 209: O: When the filesystem suddenly is set read-only (e.g. because of a ! 210: problem) some kernel functions seem not to obey the RO flag. In this ! 211: case, the dmsdos driver itself rejects the command in order to ! 212: avoid trashing the filesystem. There's notably a problem with the ! 213: FAT driver, which seems to poke around in the FAT randomly after having ! 214: just set the filesystem to read-only mode by a filesystem panic (argh). ! 215: The reason is unknown (well, it doesn't seem to be really in the FAT ! 216: driver). To be safe, dmsdos just doesn't allow something to change the ! 217: FAT in that case. ! 218: ! 219: DMSDOS: dblspace_mark_buffer_dirty: READ-ONLY filesystem ! 220: O: When the filesystem suddenly is set read-only (e.g. because of a ! 221: problem) some kernel functions seem not to obey the RO flag. In this ! 222: case, the dmsdos driver itself rejects the command in order to ! 223: avoid trashing the filesystem. ! 224: ! 225: DMSDOS: decompression of cluster %d in CVF failed. ! 226: E/B: There's an error in the compressed data (there should be another ! 227: message describing what exactly failed). The next time you boot dos you ! 228: should check it (including the surface test since only this test finds ! 229: compression errors). If it is okay under dos/win95 but still fails ! 230: under dmsdos, *please* send a bug report (best with raw cluster data ! 231: extracted by using duitl). ! 232: ! 233: DMSDOS: dec_sq: submethod not tested - raw read ! 234: ?: Maybe a drivespace 3 problem. Check under Win95. ! 235: ! 236: DMSDOS: delete_cache_cluster: get_ch returned NULL ! 237: ?: Shouldn't happen. This message means that the cluster couldn't be ! 238: locked during deletion. So it's deleted without locking. So what. ! 239: ! 240: DMSDOS: Deleted clusters found, removing... ! 241: I: Cleaning up stacker filesystem. ! 242: ! 243: DMSDOS: dfat cache: ! 244: I: Debug message. Ignore. ! 245: ! 246: DMSDOS: dirty cluster %d on dev 0x%x removed, data are lost ! 247: O/E: The driver is giving up that cluster. Writing has failed more than ! 248: 5 times. YOU HAVE BEEN WARNED 5 TIMES! In order to prevent a system ! 249: lockup caused by endless loops the driver has thrown the data away. ! 250: THE DATA ARE DEFINITIVELY LOST NOW. Very likely the filesystem is ! 251: damaged now and a part of a directory is also lost. ! 252: The driver sets the filesystem to read-only mode (printing it in the ! 253: next message). This is a really bad situation. You'd better boot Dos ! 254: and have the CVF maintainance software repair what can be repared. ! 255: If the CVF repair tool permits it, save all lost clusters - they are ! 256: likely to contain some of the lost files. ! 257: ! 258: DMSDOS: Dirty virtual sector cannot be written - FILESYSTEM DAMAGE POSSIBLE! Trying to delay write. ! 259: O: THE FILESYSTEM IS FULL! It's even so full that some clusters cannot ! 260: be written back to the disk (they're kept in memory instead). Free up ! 261: some space IMMEDIATELY! Otherwise your filesystem will be destroyed ! 262: on unmount. After some warnings (the number depends on your cache size) ! 263: the driver will give up and stop the system with a panic. ! 264: ! 265: DMSDOS: dos max_cluster=%d too large, cutting to %d. ! 266: E?:Seems to be a filesystem error. Verify that dmsdos recognized the FAT ! 267: bit size correctly. If it hasn't, this is a bug. ! 268: ! 269: DMSDOS: error in DS-0-x compressed data. ! 270: E: There's an error in the filesystem. The next time you boot dos you ! 271: should check it (including the surface test). ! 272: ! 273: DMSDOS: error in JM-0-x compressed data. ! 274: E: There's an error in the filesystem. The next time you boot dos you ! 275: should check it (including the surface test). ! 276: ! 277: DMSDOS: Error while reading an mmap file %d <> %d ! 278: E: There should be another message describing the error more exactly. ! 279: ! 280: DMSDOS: evaluate_option: loglevel set to 0x%lx. ! 281: DMSDOS: evaluate_option: speedup set to 0x%lx. ! 282: I: The messages tell it all. ! 283: ! 284: DMSDOS: exit_daemon: counter<0 ??? ! 285: B: Shouldn't happen. ! 286: ! 287: DMSDOS: FAT bit size not recognized, guessed %d bit ! 288: I: The driver did not find a valid FAT size entry in the CVF super block ! 289: and the emulated boot block, so it guessed the FAT size according to the ! 290: CVF size. This may indicate a minor filesystem error or incompatibility. ! 291: ! 292: Warning: There's a small chance to guess the wrong FAT bit size, so be ! 293: careful. ! 294: ! 295: Note: This message may appear on all stacker filesystems since they ! 296: don't seem to have a FATxx signature in the bootblock. ! 297: ! 298: DMSDOS: FAT crosslink or loop in CVF detected (cluster %d), giving up. ! 299: E: There's a FAT level error in your compressed filesystem. This is ! 300: a serious error you should immediately repair by running dos scandisk. ! 301: ! 302: Note: Verify with dutil that dmsdos has recognized the right FAT ! 303: bit size. If it hasn't, this is a bug. ! 304: ! 305: DMSDOS: FAT size does not match cluster count. Mounting READ ONLY. ! 306: E: Error in stacker filesystem. ! 307: ! 308: DMSDOS: file_mmap_nopage: no memory! ! 309: O: Shouldn't happen. ! 310: ! 311: DMSDOS: file_read: inode = NULL, rejected. ! 312: DMSDOS: file_read: mode = %07o, rejected. ! 313: B: Maybe a bug in the FAT driver or the rest of the kernel. ! 314: ! 315: DMSDOS: file_readx: FAT mismatches file size for ino=%ld ! 316: E/B: FAT error or bug. ! 317: ! 318: DMSDOS: filesystem on dev 0x%x probably damaged, set to READ-ONLY mode ! 319: E: The message tells it all. You'd better boot Dos and have your CVF ! 320: maintainance software repair the CVF. ! 321: ! 322: DMSDOS: file_write: READ-ONLY filesystem ! 323: O: When the filesystem suddenly is set read-only (e.g. because of a ! 324: problem) some kernel functions seem not to obey the RO flag. In this ! 325: case, the dmsdos driver itself rejects the command in order to ! 326: avoid trashing the filesystem. ! 327: ! 328: DMSDOS: find_free_bitfat: free sectors=%d, cannot believe this. Counting... ! 329: B: Something is wrong with the free sector count. The driver tries to ! 330: correct this by counting the free sectors again. This is a minor bug. ! 331: ! 332: DMSDOS: find_free_bitfat returned sector %d size %d but they are not all free! ! 333: B: Cannot happen. (Uh, oh... happened in dmsdos <= 0.6.3. Don't use them.) ! 334: ! 335: DMSDOS: fraglist!=mde cluster %d sector %d!=%ld or count %d!=%d ! 336: E: Error in drivespace 3 filesystem. Check under Win95. ! 337: ! 338: DMSDOS: free_ccache_dev: oh oh, freeing busy cluster... ! 339: B: Bug in cluster cache code. Expect a crash or hang soon. Please report. ! 340: ! 341: DMSDOS: free_cluster_sectors: error in fragmentation list in cluster %d ! 342: DMSDOS: free_cluster_sectors: first fragment wrong in cluster %d ! 343: DMSDOS: free_cluster_sectors: fragmentation list unreadable in cluster %d ! 344: E: Error in drivespace 3 filesystem. Check under Win95. ! 345: ! 346: DMSDOS: free sectors=%d ! 347: I: The number of free sectors is displayed. ! 348: ! 349: DMSDOS: free sector finding statistics: ! 350: I: Debug message, ignore. ! 351: ! 352: DMSDOS: get_ch: actual looks modified ARGHHH, retrying ! 353: DMSDOS: get_ch: free looks modified ARGHHH, retrying ! 354: I: Debug message. Ignore. (This messages may be important to verify that ! 355: new SMP safe cluster locking works correctly.) ! 356: ! 357: DMSDOS: get_ch: free->c_count!=0 ! 358: B: Shouldn't happen. Indicates a bug (probably leak) in cluster caching ! 359: code. ! 360: ! 361: DMSDOS: get_ch: max_retries reached, breaking loop. This may be a bug. ! 362: B?: Shouldn't happen. Indicates that the driver broke an endless loop ! 363: to prevent a complete system hang. If you haven't run horribly out ! 364: of memory and you aren't loading the system to death this is an ! 365: extremely unlikely situation. Very suspicious to be a bug. ! 366: ! 367: DMSDOS: get_ch: oldest->c_count!=0 ! 368: B: Shouldn't happen. Indicates a bug (probably leak) in cluster caching ! 369: code. ! 370: ! 371: DMSDOS: get_cluster failed (FAT problem ?) ! 372: O/E: The FAT driver returned an error. Maybe a problem with the FAT. ! 373: ! 374: DMSDOS: giving up after %d errors. There may be more errors. ! 375: I/E: The filesystem check tries to continue after the first error was ! 376: detected, but it definitely stops after 20 errors in order to prevent ! 377: your syslog from becoming larger than the errorneous filesystem..... ! 378: ! 379: DMSDOS: illegal dfat access (cluster=%d max_cluster2=%d) ! 380: ?: Bug or filesystem error. ! 381: ! 382: DMSDOS: illegal fragcount in cluster %d ! 383: E: Error in drivespace 3 filesystem.

This is a ! 446: serious error you should immediately repair by running dos scandisk. ! 447: ! 448: DMSDOS: MDFAT entry invalid (cluster %d, sect %d) ! 449: DMSDOS: MDFAT entry invalid in CVF (cluster %d) ! 450: DMSDOS: MDFAT entry invalid in CVF (fragmented cluster %d fragpnt %d) ! 451: E: There's a problem with your compressed partition. Dmsdos ignores ! 452: invalid entries if they are assigned to a file (the file will be ! 453: unreadable). ! 454: ! 455: DMSDOS: MDFAT-level dead sectors found in CVF (cluster %d) ! 456: DMSDOS: MDFAT-level dead sectors found, removing... ! 457: E/I: The driver has found sectors in the filesystem that belong to a ! 458: non-existing cluster. Depending on the repair flag, it tries to ! 459: repair the problem. ! 460: ! 461: DMSDOS: MDR signature found at sector %d ! 462: I: Debug message. Usually shows the number of the last sector in the CVF. ! 463: ! 464: DMSDOS: MDR test breaks at i=%d ! 465: I: Debug message that is produced during CVF size test. There's very ! 466: likely also a message 'access beyond end of device' logged just before ! 467: this message. It's part of the MDR test to provoke an access beyond ! 468: the device end.
