SubjectRemoving bad fsck inode files
Date
Hello,

I recently caused a significant amount of corruption on a disk by writing a
large amount of mpeg 4 frames onto a component disk of my raid array. My
fault, no doubt.

Anyway, I fsck'd the array and after a bunch of tweaking recovered most of
the data and was able to replace from backup whatever was lost.

However, during the fsck process I got a large number of files in
lost+found. No surprise there, but many of them are corrupted enough not to
be removable. As it stands now I have 13,000 files in lost+found that I
can't rm as root, or chown, or chmod.

[root@music lost+found]# rm -f \#10002*
rm: cannot unlink `#1000262': Operation not permitted
rm: cannot unlink `#1000265': Operation not permitted
rm: cannot unlink `#1000271': Operation not permitted

Broken pipe

Does anyone have any suggestions as to how to remove these? fsck does not
seem to have a problem with them.
