# dmeventd could be configured to unmount the filesystem automatically

# after the IO errors. That is racy with the umount we're trying to do
|
|
# here because there's a window in which the directory tree has been
|
|
# removed from the mount namespaces (so the umount call here sees no
|
|
# mount and exits) but the filesystem hasn't yet released the block
|
|
# device, which causes the vgremove here to fail.
|
|
#
|
|
# We "solve" the race by repeating the umount/lvm teardown until the
|
|
# block device goes away, because we cannot exit this test without
|
|
# removing the lvm devices from the scratch device -- this will cause
|
|
# other tests to fail.
