Description Zhenyong(Jerry) Jiang 2007-10-10 05:46:21 UTC 
Description of problem:

When I add 8 fence devices to my cluster, the fenced daemon can not recognize
the last four fence devices.

I found it was an limited in the fenced/agent.c

MAX_DEVICE=4

I think this patch can fix it.

This has been fixed by the fix to bz#284701 where MAX_DEVICES was bumped to 8.

Fixed in fence-1.32.63-1 and beyond.
