RE: service state unchanged when host crashes

Hi Giacomo,

Given the nature of the bug, does this mean that the unpatched cluster code is unable to relocate services in the event of node failure ?

If so, how can anyone be using this ?

regards,
Martin

I've had this bug too using Gentoo and RHCS stable-2. After a bit of investigation I've found the bug and the solution (a small, tiny, trivial 2-line patch to fenced) I've already posted on RH bugzilla but got no response.
https://bugzilla.redhat.com/show_bug.cgi?id=512512

The patch worked out for me and cluster is in production from august.
Hope it helps.
