Before upgrading to Proxmox 6 you need to upgrade to Corosync 3. Here's an ansible playbook that will automate that…
Just a quick note before I forget what little I understand. Something happened (or because I installed proxmox on top of an existing debian install, I honestly can't remember since it was like 4 weeks ago) during my install of proxmox. Long story short is that the nfs server doesn't work on reboot.
$ showmount -e clnt_create: RPC: Program not registered
So then if you manually run
$ rpc.mountd $ showmount -e Export list for proxmox-1 /tank/etc 192.168.1.0/24
But then you can't actually mount anything until you run
$ rpc.nfsd $ mount proxmox-1:/tank/etc /tmp/etc # totally works $ ps auxw |grep rpc.nfsd # no results
So I'm not sure what's going on. I do know that the half
systemd scripts are somehow buggy.
The really crappy thing is that until I figure out the real solution I can't safely reboot my boxes.
