RN214 Data Consistency

Hi

 

I just replaced one of the disks that had failed 

 

How do I run a data  and filesystem consistency check manually?  The device is syncing right now but I will feel a lot more comfortable if I could run an explicit consistency check.  I plan to replace one more disk in the near future

    The recommended way to do this on a mounted file system is to do a btrfs scrub.  You can run a scrub from the volume settings wheel - and that will do both a RAID scrub (which you don't really need for this) and a btrfs scrub.  You could also enable ssh, and run the btrfs scrub from the command line.  One benefit of using the CLI is that you have control over the scrub parameters, another is that you would only be running the btrfs scrub.

     

    BTW, you can set up a maintenance schedule from the volume settings wheel - scheduling scrubs, disk tests, defrags, and btrfs balances as desired.   I rotate through one test per month on my own NAS (running each every 4 months).
