RN2120 Full Disc Inactive Volumes

Question

HI, Its been a while since I have gone and purged my 24/7 video recordings, as I went to check on my files I couldn't access the folders on the NAS anymore, I can still log in and navigate through the OS through the IP address but all drives are shown as inactive. From the Kernel.log file this is whats shown:

Feb 21 18:35:07 nas-36-12-CE kernel: BTRFS critical (device md127): unable to find logical 13915984560128 len 4096

I had no idea that the discs become inaccessible when full, is there a way to access the drives to make space for further operation?

Thanks,

It can be.&nbsp; Netgear does offer a data recovery service, but recently folks have had trouble accessing it.

There are some cases where you can forcibly mount the volume.&nbsp; Seeing if that is possible would require a full analysis of the log zip file.

They don't always, but running out of free space can result in the file system becoming corrupted.
&nbsp;
It's not the only cause though - are you sure that the issue was a result of a full volume?

If you have a backup (or don't need the data), then the simplest path is to destroy the volume and re-create it.
&nbsp;
If you need to offload data, you will probably need data recovery.

The performance status of all 4 discs appears healthy. Is it possible to go into read only mode to take out the important files first?&nbsp;

Sandshark · Answer

By definition, you cannot delete anything when in read-only mode.&nbsp; Have you even been able to boot to read-only mode?

I haven't tried the boot menu yet, I was hoping to enter the read-only mode in an attempt to copy out the important files. Is it possible to get to the boot menu from the IP Admin page or do I have to physically be at the unit and go through the reset button sequence during boot up?&nbsp;
