This does seem unrelated to the cluster software per se, and more<br>
likely to be a GFS2 issue.<br>
<br>
But for the record, the upstream software has no official limit on node<br>
count; the only limits are in practice (network capabilities vs.<br>
Corosync's token passing algorithm). Commercial support like RHEL<br>
generally imposes their own limits based on practicality -- often 16 or<br>
32 full cluster nodes (more are possible with Pacemaker Remote).<br>
