Readynas Data Volume Full - Stuck booting at 99%
Hello,
My data volume /data is full and my Readynas 516 is stuck booting at 99% (Status: System starting up). Is there a way to get past this so I can free up some space? I've looked at previou...
Hello,
Thanks a bunch for your quick response. I can SSH into the NAS no problem, just can get to the web console. I purchased my NAS in April of 2014. I would definitely be willing to pay for support if thats the only option? Thanks again for your help.
Sorry meant to say I can't get to the web console. I can SSH into the box though.
So you can see your files in /data from ssh? If so, you can delete some from there. You can also list and delete snapshots. btrfs subvolume list /data will give you the list of subvolumes (shares) and snapshots. You can then delete a snapshot using btrfs subvolume delete <path>
After you clean up the space, you might also need to finish with a btrfs balance (also from ssh).
Cleaning up the space might not solve your booting issue though.
Hi StephenB,
Thanks for the suggestion, I can list (btrfs subvolume list /data) the subvolumes, but unfortunately when trying to delete snapshots (btrfs subvolume delete /data/directoryname/.snapshots/XXX/snapshot) the command hangs.
Is df showing that the volume is full, or is it btrfs fi df?
Do you have a full backup? If not, this would be a good time to make one. You can mount a USB drive manually.
Then maybe try
btrfs balance start -v -dusage=0 /data
This will reallocate any unused blocks to free space - which could free up a bit of free space.
