I like to ask for some recommendations here. 1) For /usr/libexec/ganesha/ganesha-ha.sh, as we have been taking advantages of using pacemaker+corosync for some other services, however, we always run into the issue of losing other resources we setup in the cluster when we run ganesha-ha.sh add/delete. Just like to know if that's what is expected? I have already tried 2 different setups, they both give me the same result, just like to better understand if i need to find a way to work around for our environment.
Do you mean you are using pacemaker+corosync to manage services other than nfs-ganesha and you loose those resources when ganesha.sh add/delete operation is performed? Could you please provide details about those resources affected?
2) Have anyone of you running into a scenario - with a demand of only adding capacity to the Gluster volume, but not necessary to add more nodes available to the Cluster? Meaning, continue adding bricks accordingly to the existing Gluster volume, but without doing the ganesha-ha.sh --add node process? Is it a bad idea? Or, between Ganesha, and Gluster, do they have to have same number of "HA_CLUSTER_NODES" as the number of Gluster peers?
Its perfectly acceptable. Ganesha cluster is a subset of Gluster trusted storage pool. So you can increase the capacity of gluster volume without the need to alter the nfs-ganesha cluster.
3) Have anyone in the list tried adding nodes into Ganesha without using ganesha-ha.sh? And, just by using "pcs"? Ganesha team, do i miss any other resource, and constraints for new nodes? a) nfs_setup/mon/grace-clone b) [node]-cluster_ip-1, c) location constraint for each member-node with score priority d) location-nfs-grace-clone e) order constraints
I am not sure if any one has tried out that. We strongly recommend to use the ganesha.sh script as there could be additions/fixes which went in that script w.r.t cluster configuration. You may have to double-check the resources and constraints every time you try to configure them manually. Do you see any difference between using the script and the manual configuration?
Thanks, Soumya
