Hi folks, this looks very weird to me. My wheezy system claims that a filesystem is mounted, but the mount directory appears to be empty and umount fails because the filesystems is not mounted, after all:
| # grep backup /etc/fstab
| /dev/mapper/backup-decrypted /srv/backup ext4
noatime,nodiratime,barrier=1,noauto,nodelalloc 0 0
|
| # mount | grep backup
| /dev/mapper/backup-decrypted on /srv/backup type ext4
(rw,noatime,nodiratime,nodelalloc,data=ordered)
|
| # df -h /srv/backup/
| Filesystem Size Used Avail Use% Mounted on
| /dev/mapper/backup-decrypted 2.5T 1.8T 699G 72% /srv/backup
|
| # ls -la /srv/backup/
| total 8
| drwxr-xr-x 2 root root 4096 Oct 21 2011 ./
| drwxr-xr-x 11 root root 4096 Oct 22 2013 ../
|
| # umount /srv/backup
| umount: /srv/backup: not mounted
I don't think it's important, but the filesystem is encrypted using LUKS
on top of an LVM volume:
| # grep backup /etc/crypttab
| backup-decrypted /dev/mapper/backup2-lvol0 none
noauto,luks,cipher=aes-cbc-plain:sha256
Interestingly, when I mount /srv/backup again, I can see its contents
and umount it afterwards. But only once. Complete transcript:
| # mount /srv/backup/
|
| # ls /srv/backup/
| abattoir/ abattoir-winxp/ cupcake/ jigsaw/ lost+found/ mail/ manowar/
_manual/ xenhost/
|
| # mount | grep backup
| /dev/mapper/backup-decrypted on /srv/backup type ext4
(rw,noatime,nodiratime,nodelalloc,data=ordered)
| /dev/mapper/backup-decrypted on /srv/backup type ext4
(rw,noatime,nodiratime,nodelalloc,data=ordered)
|
| # umount /srv/backup
|
| # umount /srv/backup
| umount: /srv/backup: not mounted
Do you have any ideas what's wrong?
Regards,
J.

I will not admit to failure even when I know I am terribly mistaken and
have offended others.
