    [TUTORIAL] PoC 2 Node HA Cluster with Shared iSCSI GFS2

    So, now I know why GFS2 is unsupported from proxmox side... It works and performance was also very good, but it breaks after some time (more than half a year). Then it is pain, when everything is stuck and all pve nodes need to be restarted and then fsck run. This is what you don't want from VM...

    What is the default migration network ?

    When 3 node CEPH cluster is setup using full mesh - routed mode, is it possible to use this ceph network for migration as well? In GUI I have to select interface, but actually there are two interfaces in this case, each to different node.

    Fibre Channel SAN connectivity.

    You can do it by disk passthrough (cli). https://pve.proxmox.com/wiki/Passthrough_Physical_Disk_to_Virtual_Machine_(VM). Since FC SAN devices usually have multiple paths, you have to configure multi path https://pve.proxmox.com/wiki/Multipath#Set_up_multipath-tools and then pass to vm this dm...

    I have manually cleared (lvremove) invalid snapshots & updated to latest from pve-test. Then I had to set "10.0+pve1" as machine version. After this, create snapshots is working again. If they break it again on current I will open Bugzilla ticket.
