Stale NFS file handle after power loss
Hi,
I had a power loss on my btrfs file system during package installation and now I found this:
<code>
% ls -l /var/lib/dpkg/tmp.ci
ls: cannot access /var/lib/dpkg/tmp.ci/conffiles: Stale NFS file handle
ls: cannot access /var/lib/dpkg/tmp.ci/md5sums: Stale NFS file handle total 0
-????????? ? ? ? ? ? conffiles
-????????? ? ? ? ? ? md5sums
% sudo rm -rf /var/lib/dpkg/tmp.ci/conffiles
rm: cannot remove ‘/var/lib/dpkg/tmp.ci/conffiles’: Stale NFS file handle </code>
I booted with a live system and ran btrfsck (without --repair!) but this did not change the situation. Unfortunately I wasn't clever enough to save the output of btrfsck somehow. Do you need it?
Could you help me to get rid of these bogus files, please?
Regards,

Don't run with --repair, but please capture the output so I can see what's going wrong. Thanks,

Hi Josef,
do you think that you might find some solution to this problem or should I plan to re-setup my machine?

Hi Josef,

Yup sorry I just got sidetracked, I'll see what can be done tomorrow, but your best bet it so pull down the latest btrfs-progs and build it and run
./btrfs-image /dev/whatever blah.img
and put the image up somewhere I can pull it down so I can fix btrfsck to fix your file system and test it locally before I send you the patch. Thanks,
Josef

Would it be possible to get this sort of thing fixed in the kernel by a scrub?
I've had a similar problem to Thomas (coincidentally also under /var/lib/dpkg) and I created a new filesystem and copied all the files across. That wasn't particularly difficult as the system was a virtual machine, but it was still rather annoying.
Also if a file is corrupted then I think that rm -f should work to remove it. In the example cited the system would be in a good functional state after "rm -f /var/lib/dpkg/tmp.ci/*" and it seems to me that file corruption shouldn't be a good reason to prevent that operation from completing.
