BTRFS command not found

ReadyNAS 102 running 6.10.5 hotfix 1

 

Trying to stop a volume balance that is at 28% after 20 hrs and causing very slow performance by using command from SSH session:

 

btrfs cancel volume /data

 

This returns:

 

bash : btrfs: command not found

Is this command not in the bash shell? Or not installed?

 

Would appreciate some insight into getting this command to run...thanks.

    Are you logging in as root (using the NAS admin password)?

      I suggest you also look for errors on the drives.  Even a volume that's had a lot of changes since the last balance or even been balanced wouldn't normally require that much time.  But disk access errors could cause it to lengthen that much.

        The time to run a balance does depend on the amount of work the filesystem needs to do.  So it can take a very long time,

         

        But I agree that looking for errors is a good idea.  Also, if you aren't certain if you are using SMR drives or not, you might want to research that. SMR drives have very uneven write performance, and that could also be the problem here.

      I was able to figure this out with some help from my dear friend Mr. Google.

       

      Thank you anyway!
