I have 3 Proxmoxs (ve 4.1) setup in a Cluster.
They had an NFS storage attached to them (synology cluster) with an active and a passive node.
I decided to cut them out of the proxmox just after i have free them of any VM or backups,...
Everything is working fine but at this point, something weird appended.
My 3 Proxmoxs was marked as down on my monitoring platform (Observium)(SNMP) No additional information in the log, just "device changed state to down".
I have not shut them down yet(synology), disabling the NFS sharing was enough to produce that issue.
I have disabled that NFS storage and deleted it on the proxmox. they don't use it anymore.
But as i said, cutting NFS sharing on the synology mark the proxmoxs as down in my monitoring platform.
But Proxmoxs are working fine.
I did not find something useful on google to help me with that problem
So i am asking you your help =)
If you got some ideas or if you have already experienced this issue.
