Subject: btrfs defragment: ioctl failed, ret -1 errno 28
Date: Tue, 18 Oct 2011 12:50:02 +0200 [thread overview]
Message-ID: <4E9D59DA.4000403@wpkg.org> (raw)
I'm trying to defragment a 280 GB file when running 3.1.0-rc9 kernel:
# filefrag /mnt/btrfs/images/srv1-backup.qcow2
/mnt/btrfs/images/srv1-backup.qcow2: 1139699 extents found
# btrfs filesystem defragment /mnt/btrfs/images/srv1-backup.qcow2
ioctl failed on /mnt/btrfs/images/srv1-backup.qcow2 ret -1 errno 28
total 1 failures
Some files fail to defragment like this; some are defragmented correctly.
Why does it fail?
