Error got inotify poll request in wrong process - disabling inotify | impossible to access VM after upgrade (25/3/21)

[Rach]

I did an upgrade today.

version :
pve-manager/6.3-6/2184247e (running kernel: 5.4.106-1-pve)

now i can't access VM via VNC via the web gui. When i launch VNC, The VM appears but the mouse doesn't move, keyboard keys have no effect... the Vm are freezing...

I found an error in pveproxy (journalctl -u pveproxy) :

Mar 25 01:00:17 ns3167785 pveproxy[18258]: got inotify poll request in wrong process - disabling inotify

I can't access my vm (ssh ports are not open) , they are behind a pfsense VM... (Host <- Pfsense <- VMs)


For information :
#cat /proc/sys/fs/inotify/max_user_instances
65536
# cat /proc/sys/fs/inotify/max_queued_events
8388608
# cat /proc/sys/fs/inotify/max_user_watches
4194304

got a server with 64G of RAM with 4 VM. i don't know what best value of inotify could be optimum.

Any suggestion ? thanks

These are normal during the operation of 'pveproxy'. They do not indicate an error.

Are you sure it's the VMs hanging, or could it just be the VNC? Maybe try a different browser, or open an SSH to at least one of them to see if they're actually stuck.
