Not sure what this test case wanted to achieve by deleting the source device before the replace. As per the comments the objective of this test case seems to be ~~~~ btrfs device replace test on RO fs Regression test for commit: bbb651e Btrfs: don't allow the replace procedure on read only filesystems ~~~~~ Also there won't be EIO when you delete a loop device when its still mounted. as shown below. mount /dev/loop0 /mnt losetup -d /dev/loop0 echo $? 0 dd if=/dev/zero of=/mnt/tf1 count=1 1+0 records in 1+0 records out 512 bytes (512 B) copied, 0.00192936 s, 265 kB/s cd /mnt sync losetup -a /dev/loop0: [0802]:1291816 (/root/testdev/disk1) No errors in the dmesg as well. Instead of further confusing, I am deleting the delete loop device part Signed-off-by: Anand Jain <anand.jain@oracle.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
