Hi,
During some btrfs-tests for my own on a btrfs-volume started with 5 devices of
different size, some snapshots and subvolumes and a few large files, I removed
one device after another (always rebalancing after remove) til I ended up with
3.
I use the latest btrfs-tools snapshot and the 2.6.32 kernel with debian patches
for sid.
btrfs-show then said:
Label: none uuid: ca5e7037-a65c-45d8-b954-f64ab0799964
Total devices 3 FS bytes used 6.01GB
devid 5 size 623.25GB used 0.00 path /dev/md15
devid 3 size 93.13GB used 9.01GB path /dev/md13
devid 1 size 9.31GB used 9.01GB path /dev/md11
Then I removed number 3.
./btrfs-vol -r /dev/md13 /home/samba/temp/btrfs-tests/
ioctl returns 0
./btrfs-show
Label: none uuid: ca5e7037-a65c-45d8-b954-f64ab0799964
Total devices 3 FS bytes used 6.01GB
devid 3 size 93.13GB used 9.01GB path /dev/sdc4
devid 5 size 623.25GB used 8.31GB path /dev/md15
devid 1 size 9.31GB used 8.31GB path /dev/md11
(/dev/sdc4 is the underlying device under /dev/md13, which I removed, I
don''t know why it still shows up as /dev/sdc4, but that happened before
with the other devices I removed, so I didn''t bother)
Now I startet to rebalance.
After 30 minutes or so ps ax still said:
17995 pts/3 S+ 0:16 ./btrfs-vol -b /home/samba/temp/btrfs-tests/
After an hour ps ax said
17995 pts/3 R+ 68:31 ./btrfs-vol -b /home/samba/temp/btrfs-tests/
and btrfs-vol consumes 100% of 1 CPU and can not be killed.
And thats what ./btrfsck /dev/md11 produced
fs tree 256 refs 1 not found

subvol00 is a subvolume I created and deleted before. The error 600 was there
before I started removing devices.
Thats what I found in the logs:
