Empty dir can't be removed ... because it's not empty?
Hi all :)
My /home is on an XFS partition all to it's own. The other day the lights went out and when I rebooted, there's an empty directory that can't be erased. This directory is a subdirectory in ~/.kde4/
The funny thing about this is that I can rename the directory, but I can't delete it:
[root@mine albumcovers]# ls
. .. cache
[root@mine albumcovers]# ls -lah cache/
total 0
drwx------ 1 rafa users 6 Jan 10 02:23 .
drwx------ 3 rafa users 18 Jan 10 02:23 ..
[root@mine albumcovers]# du -sh cache/
0 cache/
[root@mine albumcovers]# mount | grep -i home /dev/sda3 on /home type xfs (rw,relatime,attr2,delaylog,noquota)
[root@mine albumcovers]# file cache/
cache/: directory
[root@mine albumcovers]# rm -Rf cache/
rm: cannot remove `cache': Directory not empty
[root@mine albumcovers]# mv cache other_dir_name
[root@mine albumcovers]# ls
. .. other_dir_name
[root@mine albumcovers]# rm -Rf other_dir_name/
rm: cannot remove `other_dir_name': Directory not empty
[root@mine albumcovers]# ls -lah other_dir_name/
total 0
drwx------ 1 rafa users 6 Jan 10 02:23 .
drwx------ 3 rafa users 27 Jan 10 21:14 ..
[root@mine albumcovers]# du -sh other_dir_name/
0 other_dir_name/
[root@mine albumcovers]#
Kernel version: 3.1.8-1-ARCH (Arch Linux)
XFS: xfsprogs 3.1.7-1
Any idea of what's going on?
Any tool I can use to understand what's happening?
TIA
Rafa

Try to run xfs_repair on that partition.

Is your system using barriers (i.e. mounting with nobarrier option, or hardware that doesn't support FUA)? Directory corruption like this on power failure is a classic sign of a voltile drive cache being lost on power failure.
The output of dmesg from a system boot will tell us what hardware you have...

It's link count is 3, meaning that it thinks that there is an entry in the directory. You need to run xfs_repair to fix it (and whatever else is broken).
Cheers,
Dave.

Nope, no barriers. It's a single internal SATA drive. It's my personal PC at home so no fancy hardware :(

Thanks Dave and Markus. The thing is that when the lights came back on I ran an xfs_check first and got nothing (no errors). When I got the error mentioned above, I reran an xfs_check (no errors) and an xfs_repair but nothing seemed to be wrong. Yup, partition was unmounted ;)
Maybe I messed up typing the command or go figure, it was too late. That'll teach me to go to sleep at a decent time of the night ;)
In any case, I just wanted to know if maybe xfs_db or some other tool could come in handy. Can't do any more checks since I repartitioned my drive and reorganized my storage. Had backups, no data loss so it was more of a curiosity. Backups: can't live without them ;)
Thanks for your time !!
Rafa
