[SOLVED] External CEPH (PVE7) to PVE 6 Issues

[Ozlu28]

Hello All,

I have recently setup a small (currently 2 node but bringing 3rd node online soon) PVE 7 storage cluster to serve RBD to my larger PVE6 (currently) cluster.

I disabled CEPHX as its all local gatewayless networks serving CEPH data. I can see the RBD of my external cluster but the moment i put a VM onto that storage the entire PVE6 host loses connection to the cluster GUI.
The VMs on the host still function but I get connection time outs on the Summery page and on any VM attached to that host. The moment i login via SSH and remove the new VM i created (with the drive on my RBD share) everything goes back to normal again.

My larger PVE6 cluster does not have ceph installed.
PVE 7 storage cluster has CEPH Pacific on it.

Could that be the reason? PVE6 doesn't support pacific? I cant see that being the issue as it is serving from a share but I am stumped.

Thank you!

It was just a coincidence where the node i was testing the new share with had a cluster sync issue causing the GUI to go nuts.

I logged into the GUI through that nodes IP and now i see the cluster just fine.
