Missing volume after power failure
I had a power failure that lasted too long so my UPS shut down my Ultra 4 (OS 6.6.1)
When booting it up again I had this screen:
I am missing my Volume and ofc my shares too and it seems that the raid is broken since I now got a data-1?
Using ssh I can see that the volume is not mounted:
root@Ultra:~# df Filesystem 1K-blocks Used Available Use% Mounted on udev 10240 4 10236 1% /dev /dev/md0 4190208 1917460 1827244 52% / tmpfs 1017304 4 1017300 1% /dev/shm tmpfs 1017304 5468 1011836 1% /run tmpfs 508652 1020 507632 1% /run/lock tmpfs 1017304 0 1017304 0% /sys/fs/cgroup
No drives were reporting errors before so hopefully they are still ok
Is there anything I can do?
I´ve tried to reboot it a second time without change.
Any advice appreciated.

There's your issue... /mnt/data should be empty.
Do you have replicate jobs running? It's common that it pushes data to /data even though the data volume is not mounted, filling up the OS volume.
Then, once the data volume is mounted on /data, you can no longer see what was in the folder itself but the OS volume is still full.
As you have temporarily mounted the OS volume back to /mnt, you should check what's in /mnt/data and clear it to free up space on your OS volume. WARNING: Be careful what you're doing, you want to clear /mnt/data, NOT /data (where your actual data volume is mounted)!

Do you have a backup?
Not a recent one.
Well, of course you aren't entitled to normal support (even if you are willing to pay), since you are running OS 6 on a legacy ReadyNAS. Netgear can offer you a data recovery contract, but that would be pretty expensive.
Perhaps a Netgear mod here will reach out to you and offer to take a look.
Can you send in the entire logs zip file (see the Sending Logs link in my sig)?
