If the IDM lock manager fails to access drives, might partially fail to
access drives (e.g. it fails to access one of three drives), or totally
fail to access drives, the lock manager should handle properly for these
cases. When the drives are partially failure, if the lock manager still
can renew the lease for the locking, then it doesn't need to take any
action for the drive failure; otherwise, if it detects it cannot renew
the locking majority, it needs ti immediately kill the VG from the
lvmlockd.
This patch adds the test for verification the IDM lock manager failure;
the command can be used as below:
# make check_lvmlockd_idm \
LVM_TEST_BACKING_DEVICE=/dev/sdp3,/dev/sdl3,/dev/sdq3 \
LVM_TEST_FAILURE=1 T=idm_ilm_failure.sh
