Hello,

When I try to delete a device from my btrfs filesystem I always get the following kernel bug error:
	[  809.161020] kernel BUG at /home/apw/COD/linux/fs/btrfs/extent_io.c:2116!
	[  809.166761] invalid opcode: 0000 [#3] SMP
See attached log file for more details. I’m trying to delete the device /dev/sdb from my filesystem.

Steps I tried so far are:
1. mount with the clear_cache option
2. balance the filesystem (results in the same kernel error)
3. scrub the filesystem
4. btrfsck —repair

During scrubbing and btrfsck some error where found and fixed. But I think these where error caused by system lockups during copying data to the new btrfs filesystem. These lockups where caused by an extraordinary amount of hard links, since I was using rsnapshot to create hourly snapshots on my old filesystem that I am migrating towards btrfs. Removing these hard links solved the lockup problems.

Something I also noted was that after the btrfsck run, the command ‘btrfs fi show’ reported “devid    4 size 0.0GiB used 98.00GiB path /dev/sdb” (mind the 0.0GB).

I’m ready to run any diagnostics necessary, but the filesystem is 4.7T so it won’t be able to provide an image.

System details:
