Hi, While testing with my Ceph cluster I saw some btrfs messages: http://pastebin.com/URN3ShVb I'm not sure when these messages came up (What state of the OSD). To keep up with the recent btrfs changes I'm using Josef's btrfs-work repository ( aba63cd31ab85e3ec7e9805fadc77dad8b7fc945 ) with the 2.6.38 kernel. One of my OSD's (Object Store Daemons) is still blocking, this is the OSD which is using /dev/sdc (See the pastebin errors about sdc). It's in status D, the stack is showing: root@noisy:~# cat /proc/1974/task/2043/stack [<ffffffffa033fc3a>] btrfs_commit_transaction_async+0x25a/0x2e0 [btrfs] [<ffffffffa036e48e>] btrfs_mksubvol+0x2ae/0x350 [btrfs] [<ffffffffa036e62a>] btrfs_ioctl_snap_create_transid+0xfa/0x150 [btrfs] [<ffffffffa036e709>] btrfs_ioctl_snap_create_v2+0x89/0x100 [btrfs] [<ffffffffa0371692>] btrfs_ioctl+0x762/0xa90 [btrfs] [<ffffffff8116de1d>] vfs_ioctl+0x1d/0x50 [<ffffffff8116e8b9>] do_vfs_ioctl+0x69/0x1d0 [<ffffffff8116eab4>] sys_ioctl+0x94/0xa0 [<ffffffff8100c002>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff root@noisy:~# I don't know if it is related to the messages in my dmesg, but I thought i'd send it anyway. Is this a known bug?
