I am running OMV 5.6.24-1 on Raspberry Pi 4 2gb. It's been set up and running for months without issue. It has a 12tb disk mounted and runs an rsync server. My Synology backs up to OMV on a nightly basis via the rsync server.
As of the last 1/2 weeks the OMV server keeps going offline, generally once a night. It is not accessible via the ip on a web browser, the synology cannot connect to it via the rsync back up and i cannot ssh to it.
Interestingly it is still able to send out update notifications via the gmail smtp server i have set up.
The only way i can recover the server is to plug the power supply, which obviously is not good on an RPI.
Can any recommend a resolution for my issue or how i can best debug it?
I vaguely know my way round linux, but not for any specific OMV configuration.
Thanks in advance!
