Hi again!
After the reboot I first wanted to see, what the fsck had done:
xchklog /dev/sda3
xchkdmp -f fscklog.sda3 > fsck-dumped.sda3
xchklog /dev/hda1
xchkdmp -f fscklog.hda1 > fsck-dumped.hda1
There I find several lines like
"fsck service log: INVALID LOG RECORD: SKIPPING ONE OR MORE LOG RECORDS."
in both fsck-dumped.* files (both are appended to this mail).
Strange that xchkdmp cannot read all lines that xchklog created??!
But nowhere appears info about which files the fsck treated.
The directory on /dev/hda1 (AM_1353-272) where I tried to copy the
file in, is not accessible after the reboot:
> ls -laF AM_1353-272
ls: AM_1353-272: Input/output error
After unmounting I tried another fsck:
> fsck.jfs -fv /dev/hda1
fsck.jfs version 1.0.15, 15-Feb-2002
The current device is: /dev/hda1
(chklog) FSCK Open(...READ/WRITE EXCLUSIVE...) returned rc = 0
(chklog) FSCK Primary superblock is valid.
(chklog) FSCK The type of file system for the device is JFS.
Block size in bytes: 4096
File system size in blocks: 15012734
Phase 0 - Replay Journal Log
(chklog) FSCK:LOGREDO: Journal log is now open. (major = 0x00, minor = 0x00)
(chklog) FSCK:LOGREDO: Log already redone!
(chklog) FSCK logredo returned rc = 0
Phase 1 - Check Blocks, Files/Directories, and Directory Entries.
(chklog) FSCK Duplicate reference to 4 block(s) beginning at offset 2894036
found in file system object IA16.
(chklog) FSCK Inode A16 has references to cross linked blocks.
(chklog) FSCK Multiple metadata references to 4 blocks beginning at offset
2894036 have been detected.
Duplicate block references have been detected in meta-data.
FSCK CANNOT CONTINUE.
File system is dirty.
(chklog) FSCK processing terminated: 3/1/2002 22.10.58 with return code: 0.
The xchkdmp'ed log is also appended. Stupid of me to unmount it
*before* doing another backup, because now I cannot even mount it
anymore:
> mount -v /users2
mount: wrong fs type, bad option, bad superblock on /dev/hda1,
or too many mounted file systems
I also append the file with the xpeek output of the superblocks. Did
anyone write a How-To about cases like this, and what one has to do
to get the data back? Or does one have to be a JFS programmer to
know enough to do it? I have most of the data on last night's
backup, but today's work would be lost...
Greetings,
Peter.
