Package: smbfs
Version: 3.0.24-6etch10
Severity: important
After some time, my cifs mount fail.
The shares initially mount fine but after some time (often, for
instance, if I leave my media player paused instead of stopped), I am
unable to access anything. Example:
$ ls /smb/cirno/media_rw
ls: /smb/cirno/media_rw: Input/output error
dmesg symptoms are:
[17686.551543] CIFS VFS: cifs_mount failed w/return code = -6
and
[24129.293542] CIFS VFS: Unexpected lookup error -5
Both of which appear repeatedly, normally starting with the first.
While the bug is in effect, I can use smbclient on the exact share name
with no trouble, and can access differently named autofs shares on the
same server with no trouble (eg. if I refer to the server as cIrno). I
need to reboot to fix it, though the bug hangs my reboot so I need to
Magic SysRq Sync, Umount, reBoot.
The shares are pretty much un-umountable. If I try with for example
# umount -l //cirno/media
I get no error, but a short while afterwards I will be greeted by a
kernel oops. My full dmesg output (repeats marked with ...) is attached.
The server runs Samba 2:3.2.3-1 with UNIX extensions disabled (otherwise
softlinks in the shares misbehave).
I use auto.smb to mount the shares (presumably explaining the repeated
mount errors); output of auto.smb on the machine is:
-fstype=cifs,uid=1000,gid=1000,iocharset=utf8,credentials=/etc/auto.smb.cirno
\
/print$ ://cirno/print$ \
/media_rw ://cirno/media_rw \
/media_pub ://cirno/media_pub \
/media ://cirno/media \
/bucko ://cirno/bucko
The machine operates a softlinked union of 10 hard drives, all of which
are set to powersave after 20 minutes. I once caused the bug
instantaneously by attempting to list the contents of all 10 drives (which
were almost all off), then listing contents of a different alias to the
same share (I use multiple case variations of the server name precisely
due to this bug), so it may be a threading issue.
