Description Chris Pelland 2012-11-23 22:05:04 UTC

+++ This bug was initially created as a clone of Bug #871768 +++

Description of problem:
The problem is that we will stay with unresponsive host forever unless manually restarted.

Version-Release number of selected component (if applicable):
si22.1

Steps to Reproduce:
1. Assume you have 2 hosts aqua1, aqua2
2. Restart aqua1 via power management [Result: aqua1 is rebooted and up again within 90sec]
3. VDSMD on aqua1 crashed or stopped. [Result: aqua2 will send pmCommand reboot to aqua1]
The reboot attempt will fail because 180sec didn't pass yet [FenceQuietTimeBetweenOperationsInSec=180sec]
  
Actual results:
aqua1 is unresposive and vdsmd is down

Expected results:
Consider to send 2nd or 3rd reboot attempt to make sure the other host is up

Comment 3 Tareq Alayan 2012-12-18 13:47:23 UTC

couldn't reproduce.

The proxy has successfully fence the the non operational host in the 180 seconds window. 
And the host goes up.
