ReadyNAS alert: Volume Warning - looks like a full root volume

[btsixer]

I'm receiving ReadyNAS warnings stating:

Less than 30% of volume media's capacity is free. NETGEAR recommends that you add capacity to maintain current performance levels. Continuous protection snapshots will be deleted when volume free space is less than 5%.

In looking at the following solved topic, I'm sure it is the root volume that is full based on my btrfs.log

https://community.netgear.com/t5/Using-your-ReadyNAS/Volume-Warning-on-Disk-Useage/m-p/1149985#M1171...

My question is what I do to resolve the capacity issue. How do I fix?

I have a ReadyNAS516 running the newest firmware v6.6.1

Thanks.

The message is referring to the data volume.

How much of the volume capacity are you using?

Are there any apps installed?

If it is a similar problem it'll probably require remote access.

If btsizer has checked btrfs.log and the data volume is less than 70% full then it could well be the root volume.

If it is the root volume it can be fixed using SSH. It's a matter of determining what's using lots of space of the root volume and then dealing with it appropriately.

Howdy, details from btrfs.log and screenshots showing volume use attached.

That's very conclusive. You're using close to 3GB of the 4GB capacity of the root volume

Plus the first data volume is also very full.

So there are two things to take care of.

Is there a utility I can run that allows me to care for disk utilization? Should I be attempting something along the lines of balancing data volumes?

I can do some searches for command line root cleanup but anything you can suggest would be helpful to get me started.

Thanks.

Just found this KB:

Scrubbing

Defrag

Balancing

I'm going to back up the entire NAS and then take the storage offline and go through the process of cleaning everything up.
