Subject: btrfs: kernel BUG at fs/btrfs/volumes.c:3653
Date: Fri, 25 May 2012 18:16:13 -0400 [thread overview]
Message-ID: <20120525181613.180b3659@zee.bluelavalamp.net> (raw)
I have a btrfs volume that's made up of 10 devices, only one
filesystem on the volume. Have been running this for probably over a
year. Recently noticed kernel oops, in syslog there's this:

As soon as the filesystem is mounted this happens, also get this at the console:

I can read the files and copy them to other drives. I can't do a software reboot, using the reboot command the machine just hangs and waits forever so I have to do a hard reset. Sometimes I can delete files, but after the hard reboot they are back. Other times I'll try to delete a file and the rm command just hangs. I can still use the machine and all other filesystems work fine. Thought it was maybe being low on space, this is what btrfs-show reports:

Tried adding a drive but get an error back:
www:# btrfs device add /dev/sdh1 /videos
ERROR: error adding the device '/dev/sdh1'
Not sure what to try next, any suggestions?
Thank you in advance,
Kevin
