[DRBD-user] Pacemaker cluster with DRBD on ESXI - Fencing on snapshot

[jota at disroot.org]

Hello all,

I am experiencing issues with a pacemaker cluster with drbd.

This is the environment:
2 nodes (CentOS 7.5) - VMs on ESXI 6.5
pcs version 0.9.158
drbd 8.4

All nights,I have scheduled a backup with HPE RMC within vSphere. This job performs a snapshot of the datastore volume containing the vms, and at the same time, through the vmware-tools, performs a snapshot of each vm.
This results on a fencing of each master node every night. Master node has scheduled the backup at 21:00. When it is fenced, the resources goes to the secondary node, that becomes primary. As the second node has scheduled the backup at 22:00, at that time it is fenced too.
Is it possible (and safe) to increase some timeouts in order to avoid this?

Regards,

Jota.
