Subject [jira] [Resolved] (CLOUDSTACK-5470) Xenserver - Host continues to remain in "Up" state when powere off due to exception - "Unable to reset master of slave"
Date Thu, 19 Dec 2013 07:11:07 GMT

     [ https://issues.apache.org/jira/browse/CLOUDSTACK-5470?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Koushik Das resolved CLOUDSTACK-5470.
-------------------------------------

    Resolution: Cannot Reproduce

Snapshots don't have any impact on the status of host.
This also looks like a XS setup issue similar to CLOUDSTACK-2428 where hosts in a cluster
are not time synced.

Please reopen if you still see this issue after fixing the time sync. problem.
