[ClusterLabs] What is the current state of the art in setting up HA NFS?

2020-02-17 Thread Dennis Jacobfeuerborn
Hi, what are the current best practices to set up a HA NFS Server? I see that EPEL no longer contains the drbd packages for CentOS 8 for example. Also a lot of documents on the internet still refer to either Pacemaker 1.x or meddle with the fsid which apparently is no longer recommended. What is

Hi, I'm currently trying to set up a drbd 8.4 resource in a 3-node pacemaker cluster. The idea is to have nodes storage1 and storage2 running with the drbd clones and only use the third node storage3 for quorum. The way I'm trying to do this: pcs cluster cib cib.xml pcs -f cib.xml resource create

Hi, I'm setting up a redundant NFS server for some experiments but almost immediately ran into a strange issue. The drbd clone resource never promotes either of the to clones to the Master state. The state says this: Master/Slave Set: drbd-clone [drbd] Slaves: [ nfsserver1 nfsserver2 ]
