Cluster crashes when using long parameter in cluster.conf
Issue
When trying to include long parameters into the file /etc/cluster/cluster.conf (e.g. SCSI fencing devices that are used in configuration) corosync crashes with signal 6 and coredumps. For example following configuration works:
<fencedevice agent="fence_scsi" devices="/dev/a1,/dev/a2,/dev/a3,/dev/a4,/dev/a5" name="SCSI_Reservation_Fencing"/>
But following doesn't:
<fencedevice agent="fence_scsi" devices="/dev/a1,/dev/a2,/dev/a3,/dev/a4,/dev/aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa5" name="SCSI_Reservation_Fencing"/>
This "aaaa" name is used to verify the problem. Originally we had five entries like "/dev/disk/by-id/dm-uuid-mpath-360a9800037543735305d424147624b7a".
