ReadyNAS RN104 unreleased HD space

Hi, I have a ReadyNAS 4 bay system with 4 x 2TB Hard disks set up as a RAID 5 with a capacity of 6TB. The firmware is 6.10.1 and the system and all volumes are healthy. The system is showing less tha...

Hi Stephen,

I am not sure how the ReadyNAS splits Volumes and Shares. When I go to the Volumes tab I see one picture of the RN104 with 4 disks inside and RAID 5 underneath, so I assume I have one volume. When I go to the shares tab I see seven shares which I assumed are like folders.

 

I do not have a backup as such as I do not have another hard disk large enough. I have duplicate copies of all the files in to different location, most on an older NAS drive and the remainder on multiple portable HD's. It would be paiful to loose the data as I would have to copy it all which is slow but at least it is safe on another system.

 

I am OK using SSH commands, I am purely a MAC user having dropped the Microsoft Blue Screen of death a few years ago. I can also run Red Hat Linux on an old PC, if I cannot achieve the same result in the command line on my MAC.

 

Thanks

 

Ian

XRAID has one volume, which is named data.

 

Enable ssh in system->services->settings.  Then log in as root using the NAS admin password. Then look for the snapshots by entering 

# btrfs subvolume list /data

 

If you can see them, then you can manually delete them with

# btrfs subvolume delete -c /path

using the full path of the snapshot (something like /data/sharename/.snapshots/xx/snapshot).  Make sure you include the volume name - the btrfs list command doesn't include it.

 

FWIW, I recommend purchasing a disk large enough to back up your NAS first.

    Thanks very much Stephen, worked perfectly. Hard Disk space is still freeing up but at over 1Tb now, I am guessing it take a while to sort itself out when you delete stuff.

     

    Thanks Again

      I'm glad I could help.

      Yes.  I suggest running a balance from the volume settings wheel - that will also help free up space.
