ReadyNAS 104 Remove inactive volumes to use the disk. Disk #1

[readlouis]

Recently got this error on my NAS when looking at the admin page. Was wondering if their was any solution to this issue any help would be appreciated.

The error is either due to the RAID array failing to be assembled, or due to BTRFS file system errors on the volume.

Hard to tell from your screen shot, but in general if you have this error you also aren't able to access your data.  Is that the case for you?

I can still access my data and transfer to and from the NAS

I recommend backing up the files.  Also download the full log zip file and look in there for errors.

Are you using X-RAID or FlexRAID?

Has the NAS experienced a power cut or an unclean shutdown?

Hello @readlouis ,

And welcome to the NETGEAR Community! 🙂

As @StephenB  mentioned it might be a BTRFS file system error probably. We would require logs to investigate further. Are you falling under warranty? Please provide your Serial Number to check for support eligibility.

Have a lovely day,

I have used the RAIDar app to look at the diagnostic information this is what i got.

Do you have a backup of the data on the NAS?

If not, do you have experience with the linux command line (ssh)?

[readlouis]

I have a backup of the data and have used SSH a little bit in the past.

Good to know.

The simplest solution is to do a factory reset, reconfigure the NAS, and restore the files from your backup.

The rationale is that the full root partition often results in corrupted NAS configuration files, so you have potentially more than one problem to try to manually fix.

Starting over gives you a completely clean system, so no possibililty that something missed in a manual repair will cause more trouble later on.

But you also need to find out what caused the OS partition to fill, or you'll likely be here again.  So poking around via SSH to identify the files that are the issue will usually often identify their source.

Reasonable if you know what you are looking for.  Another option is to keep an eye on the OS after the reset, and see if it begins to fill.  Note that if SSH isn't enabled, you'd need to boot into tech support mode in order to take a look.
