[mythtv-users] Terminal hangs when trying to mount LVM vgroup

[Azmat]

Hi,

I'm running MythTV on Fedora Core 5 using an LVM filesystem to store
my recordings. The other night, when it was about to start recording a
show, the recording started to hang. I killed the program and the
server and decided to reboot the machine. When it came back up, I
tried remounting the LVM group:

mount /dev/MythVideo/video /video

But the terminal hangs on this command and can't be aborted with ctrl-c.

Looking at the output from dmesg, I have:
ReiserFS: dm-0: Removing [4 480 0x0 SD]..<4>ReiserFS: dm-0: warning:
PAP-5660: reiserfs_do_truncate: wrong result -1 of search for [4 480

I don't know what this message means. I tried to include the messages
from my /var/log/messages, but trying to output this long hangs the
terminal in a similar manner as the mounting command.

Here's the output from vgdisplay -v:

Has anyone else encountered this? I tried umounting /video just in
case it was still mounted:

[root at filmfreak mythtv]# umount /video
umount: /video: not mounted

I don't know what else to try but I'm open to ideas.

Thanks.
