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? attachment: create bash: pcs_create.sh create log: pcs_create.log _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
Hi, you could try to create cluster CIB configuration with pcs commands on a file using the '-f' option and then push it to the pacemaker all at once. pcs cluster cib > original.xml cp original.xml new.xml pcs -f new.xml <command> ... ... pcs cluster cib-push new.xml diff-against=original.xml And then wait for the cluster to settle into stable state: crm_resource --wait Or there is pcs command since version v0.11.8: pcs status wait [<timeout>] I hope this will help you to improve the performance.
