Remove inactive volumes after clearing root usage is 91%

Question

Hi, Wondering if somene could help me with my readynas issue.

The device was complaining about volumn 30% remaining for a few days, which I ignored becuase the frontview showed I had 3TB free.

Then a few days later I could not login to the frontview. Logged into server via SSH and noticed logs error:

LOGMSG_SYSTEM_USAGE_WARN System volume root's usage is 91%

Checking root I noticed a large media file so I deleted it using the rm command.

Now login to frontview is working but I have lost my volumes (attached screen shot).

Wondering if someone can help me or point me in the right direction.

Your help will be much appricated.

I redacted the log download links - logs shouldn't be posted publicly.
&nbsp;
Instead send a private message (PM) to one of the mods -&nbsp;JohnCM_S&nbsp;or&nbsp;Marc_V&nbsp;- asking them to review the logs.&nbsp; Post the download links in the PM.&nbsp; &nbsp;You send a PM using the envelope icon in the upper right of the forum page.

Hi&nbsp;Korky,

&nbsp;

It appears that the NAS detected a file system issue which caused the volume to go offline.

&nbsp;

Do you have a back up of your data?

&nbsp;

If you do not have a backup, it will be best for you to contact NETGEAR Support&nbsp;because&nbsp;there are BTRFS errors and data is involved. They will check if there still some corrective changes that can be done via backend access or if data recovery is needed.

&nbsp;

If you do have a backup, another option is to reset&nbsp;the NAS to&nbsp;factory default then recover from backup.

Regards,

Thank John,Will reinstall of the OS not resolve the issue orAdding additional disk drive?Will that make it matters worse?No, I don't have backup of the data. The the data is mostly media which I can live without. However, I do have a few GB of family photos that I would like to recover if I can.Thanks again

An OS reinstall won't help - nor will adding another disk drive.
