[lvm-devel] [PATCH v1 16/17] tests: multi-hosts: Test lease timeout with LV exclusive mode

[Leo Yan]

This patch is to test timeout handling after activate LV with exclusive
mode.  It contains two scripts for host A and host B separately.

The script on host A firstly creates VGs and LVs based on the passed
back devices, every back device is for a dedicated VG and a LV is
created as well in the VG.  Afterwards, all LVs are activated by host A,
so host A acquires the lease for these LVs.  Then the test is designed
to fail on host A.

After the host A fails, host B starts to run the paired testing script,
it firstly fails to activate the LVs since the locks are leased by
host A; after lease expiration (after 70s), host B can achieve the lease
for LVs and it can operate LVs and VGs.

  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_ex_timeout_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_ex_timeout_hostb.sh
