Nextcloud Services failed after bios reset

My Bios battery died so all bios settings including disk names were reset. Openssh service starts however all nextcloud servers output failed two times when I run systemctl list-units.
Nothing changed, same disks everything, when I find the log file, I’ll try to write an output.
I actually use not same directory for nextcloud data, I have separate disk mounted on /var where all data is stored.

It sounds like some of your disks are mounted in the OS.

Are they currently mounted? (Note: this isn’t controlled by NC but is an OS matter).
