Instance i-00000184.eqiad.wmflabs (sylvester) was up yesterday. Today it shows SHUTOFF state in Special:NovaInstance. Tried clicking "reboot" and waited a few minutes, no change. Clicking reboot again now shows a little popup message "Failed to reboot instance sylvester." Clicking "get console output" shows message "Failed to get console output for instance sylvester." Tried rebooting several times in the last hour.
No idea why this would happen. Reading something about NFS issues, I thought maybe it has something to do with disk images for the VM being inaccessible or something like that, but that's just a wild guess.
We're currently integrating catgraph with cirrus. This is a blocker for us because catgraph doesn't work without this instance. Can somebody with admin access please investigate?
