[ClusterLabs] Antw: [EXT] Cluster breaks after pcs unstandby node

2021-01-13 Thread Ulrich Windl
Hi! I'm using SLES, but I think your configuration misses many colocations (IMHO every ordering should have a correspoonding colocation). From the logs of node1, this looks odd to me: attrd[11024]:error: Connection to the CPG API failed: Library error (2) After systemd[1]: Unit

Hi. I would run nfsserver and nfsnotify as a separate cloned group and make both other groups colocated/ordered with it. So nfs server will be just a per-host service, and then you attach exports (with LVs, filesystems, ip addresses) to it. NFS server in linux is an in-kernel creature, not an

I'm having trouble setting up what seems like should be a straightforward NFS-HA design. It is similar to what Christoforos Christoforou attempted to do earlier in 2020 (https://www.mail-archive.com/users@clusterlabs.org/msg09671.html). My goal is to balance multiple NFS exports across two

Hi! I had made a test: I had configured RAM requirements for some test VMs together with node RAM capacities. Things were running fine. Then as a test I reduced the RAM capacity of all nodes, and test VMs were stopped due to not enough RAM. Now I wonder: is there a command that can list those
