RN314 "No volumes exist" mount: special device doesn't exist

Hi *,
my ReadyNAS 314 worked fine and I updated to 6.1.7. Reboot was ok and also some work...
... but since this morning (I've a power down every night) the volumes are gone!

It seames that the mound does not work:

I'd contact support if you haven't already, and get into their work queue.

Re: RN314 "No volumes exist" mount: special device doesn't e

Hi *,

the incident was solved automatically by reboot (the normal "power timer" function)... 😄
... but how to find oud the root cause?

Which are the relevant log files?
I don't use my RN every day so it may be that this was not the first day with this behaviour... how to find out older outages?
... and it may not be the last... and may be the next time it is worse and a reboot doesn't fix it.

May be I follow the advice of StephenB but not tonight.
