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? -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
