[SOLVED] GUI displays 'grayed' nodes

HI,

Installed Proxmox 4.2 on 3 nodes and formed cluster. CLI tools like pvecm status/nodes show that cluster is OK. But GUI randomly 'grays out' nodes and randomly takes them back. No errors, quorum is established. I changed to udpu and back to multicast - no difference. What should I check else?

Regards,
Alexander

systemd-timesyncd is running on all nodes without errors.

Code:
May 24 06:52:03 host3 systemd-timesyncd[982]: interval/delta/delay/jitter/drift 2048s/-0.001s/0.000s/0.001s/-14ppm

I have even switched from ntpd back to systemd-timesyncd - still no luck. What looks interesting - ceph cluster on these nodes doesn't complain about time synchronization problems.

P.S. Btw, why Proxmox starts systemd-timesyncd even if ntpd is up and running?

I found what's happening. Browser (web-interface) makes calls to https://hv01:8006 like
Code:
GET /api2/json/nodes/hv02/storage/local/status HTTP/1.1" 500 -
they are proxied to node hv02, then get locally proxied to tcp/85 where pvedaemon listens. Here is the timeout happened.

I have successfully resolved the problem. The root of issue was in creating ceph cluster with
Code:
pveceph init --network b.b.b.b/mask
where b.b.b.b/mask network is second (private) segment devoted to ceph intra-cluster communication. So the /etc/pve/ceph.conf had the following lines:
Code:
cluster network = b.b.b.b/mask
public network = b.b.b.b/mask
although public network (where all PVE cluster members act) is a.a.a.a/mask. So when GUI asks for storage status of any node, pvedaemon sends queries to ceph monitors in a.a.a.a/mask segment instead of addresses from b.b.b.b/mask network. I changed ceph monitor addresses and public network to a.a.a.a/mask and problem has gone.

So when specifying --network option with pveceph init command expect to change /etc/pve/ceph.conf to address your scheme.
