Hello Kristian, Take this perspective with a grain of salt given our time spent on this was in a proof-of-concept deployment.
We tested iSCSI connectivity with OCFS2 as the underlying technology to provide the shared mount point. We found that throughout the course of host reboots, the reliability of varying components re-establishing connectivity was not up to par with the reliability of the underlying storage technology (iSCSI). In a few cases, I found OCFS2 unable to establish peers with the other KVM hypervisors, which required rebuilding the OCFS2 cluster to re-establish connectivity. The other mechanisms to create a shared mountpont were not tested as we pivoted away from the idea given our experience with OCFS2.

Can someone recommend or share their experience with usable solutions for shared mountpoint technical solutions? It seems there are quite a few options, such as shared/clustered file systems: GFS2, OCFS2, cLVM. From the information I have found, OCFS2 seems to be the best option. P.S. I don't want to use any distributed storage like Ceph, etc. We are partially moving away from VMware, and we believe in FC NVMe old-school storages, which are the most reliable, in my opinion.
