Description

Marking this a regression since this test (cmirror_lock_stress) used to pass in RHEL5.5. There should be a 6.0 release note for this issue. FWIW, I'm able to hit this bug with mirror_sanity as well.
SCENARIO - [verify_sync_completions]
Create 8 mirrors and verify that their copy percents complete
hayes-03: lvcreate -m 1 -n sync_check_1 -L 500M mirror_sanity
hayes-01: lvcreate -m 1 -n sync_check_2 -L 500M mirror_sanity
hayes-02: lvcreate -m 1 -n sync_check_3 -L 500M mirror_sanity
hayes-01: lvcreate -m 1 -n sync_check_4 -L 500M mirror_sanity
hayes-01: lvcreate -m 1 -n sync_check_5 -L 500M mirror_sanity
hayes-02: lvcreate -m 1 -n sync_check_6 -L 500M mirror_sanity
Error locking on node hayes-03: Command timed out
Aborting. Failed to activate new LV to wipe the start of it.
couldn't create mirror:
hayes-02 lvcreate -m 1 -n sync_check_6 -L 500M mirror_sanity

Do not attempt to flood a production system with LVM commands, as the backlog of commands to be processed may increase to such a level that some operations fail due to timeouts.
