[lvm-devel] [PATCH v1 15/17] tests: multi-hosts: Add LV testing

[Leo Yan]

This patch is to add LV testing on multi hosts.  There have two scripts,
the script multi_hosts_lv_hosta.sh is used to create LVs on one host,
and the second script multi_hosts_lv_hostb.sh will acquire
global lock and VG lock, and remove VGs.  The testing flow verifies the
locking operations between two hosts with lvmlockd and the backend
locking manager.

  On the host A:
    make check_lvmlockd_idm \
      LVM_TEST_BACKING_DEVICE=/dev/sdj3,/dev/sdk3,/dev/sdl3 \
      LVM_TEST_MULTI_HOST=1 T=multi_hosts_lv_hosta.sh

  On the host B:
    make check_lvmlockd_idm \
      LVM_TEST_BACKING_DEVICE=/dev/sdj3,/dev/sdk3,/dev/sdl3 \
      LVM_TEST_MULTI_HOST=1 T=multi_hosts_lv_hostb.sh
