hi,

just upgraded to 7.2 and noticing that my cluster is in a state where:
  1. my sidebar looks like this:
    1657347636205.png
  2. I can't list or start containers on the "?" node, ibnmajid. VMs seem to work fine. Ceph seems to be fine. Info about that node:
    1657347713480.png
  3. output of pvecm status:
    root@ganges:~# pvecm status Cluster information ------------------- Name: BrokenWorks Config Version: 3 Transport: knet Secure auth: on Quorum information ------------------ Date: Sat Jul 9 01:39:05 2022 Quorum provider: corosync_votequorum Nodes: 3 Node ID: 0x00000002 Ring ID: 1.45b Quorate: Yes Votequorum information ---------------------- Expected votes: 3 Highest expected: 3 Total votes: 3 Quorum: 2 Flags: Quorate Membership information ---------------------- Nodeid Votes Name 0x00000001 1 192.168.9.10 0x00000002 1 192.168.9.11 (local) 0x00000003 1 192.168.9.12 root@ganges:~#
What else can I provide to troubleshoot?

what do you mean by that exactly? what can't you do? what error messages do you get?
 
mostly I get hanging and timeouts. if I do `pct list` *right* after restarting the node, I get the list of containers on it. if I try to start, create, or delete one, the process hangs indefinitely, and if I cancel it, `pct list` will hang just like anything else to do with containers on it.

another detail: VMs seem to mostly work on this node, but if I try to open a console on any, it also times out.

one more: if I start the MDS on this host, it sticks around for a minute and then seems to stop. other than that I have two active MDSes, which is not something I ever configured. it started doing that after I updated to 7.2.

here's what happens in syslog when I try to start the MDS:

what does 'ceph -s' say?

what else is running on that node?

can you post part of the journal when it hangs?

two VMs. one is a Windows 10 instance, one is a random Linux VM I don't need.

108 is the Windows VM that does not permit the VNC connection for the console to work.

I mean, there is ever the option to get a subscription [1] (at least basic) and open a support ticket (for setups supported by Proxmox).

Do not get me wrong, only meant as a hint. :)

I don't have $900 a year to spend on my 3-node homelab cluster. I would actually be willing to pay for a ticket on an individual basis, but that isn't an option.
