Everything seems reasonably back to normal:

Notes:

  • the machines in the control room have been rebooted;
  • the c1iscey frontend now behaves;
  • I saw on nodus, which remained up and running the whole time, a bunch of   nfs: server chiara is not responding, timed out  messages, belonging to the freezing time; it may be that the sync option for the nfs share is too resource demanding, or some other network issue;
  • the FSS was doing strange stuff and the MC couldn't recover the lock; the MCautolocker script wasn't running because of the lock loss of the MC and the lack of communication between the machines; so we did a sudo initctl start MCautolocker on megatron and recovered the MC too.
