Hi,
I am running both FreeBSD and Linux sharing an ext2 /home (on a
dedicated disk).
Occasionally (say once every month or two), FreeBSD complains on
bootup about /home and asks to run fsck on it. Here is a record of
what happened last time:
1) I was running FreeBSD day after day for quite some time
2) I rebooted to Linux to check something, no problems so far.
3) Back to FreeBSD, I get the complaint about /home
4) Reboot to Linux, and the boot-time fsck gives me:
Inode 51214, i_block is 4, should be 2...
Duplicate or bad blocks in use
Duplicate blocks found, invoking duplicate block passes
/dev/hdc1: Duplicate/bad block(s) in inode 100354 ...
/dev/hdc1: Duplicate/bad block(s) in inode 163924 ...
...
There are 2 inodes containing duplicate/bad blocks
/dev/hdc1: File "SOME_FILE_A" (inode #163924, modified ... Feb 18...)
has 1 duplicate block, shared with 2 files
/dev/hdc1: <filesystem metadata>
/dev/hdc1: "SOME_FILE_B" (inode #100354, modified ... Feb 15 ...)
/dev/hdc1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
5) Running fsck and accepting everything, solves the problem for the
time being.
Please note, that FILE_A and B are unrelated context-wise and in terms
of directory structure wise and modification/creation times, and not
always the same 2 that trigger this problem.
Thanks in advance for your help
