[ClusterLabs] poor performance for large resource configuration

[zufei chen]

Hi all,

background：

   1. lustre(2.15.5) + corosync(3.1.5) + pacemaker(2.1.0-8.el8) +
   pcs(0.10.8)
   2. there are 11 nodes in total, divided into 3 groups. If a node fails
   within a group, the resources can only be taken over by nodes within that
   group.
   3. Each node has 2 MDTs and 16 OSTs.

Issues:

   1. The resource configuration time progressively increases.  the second
   mdt-0  cost  only   8s，the last ost-175 cost  1min:37s
   2. The total time taken for the configuration is approximately 2 hours
   and 31 minutes. Is there a way to improve it?
