ReadyNAS 314 how to see resync status via ssh ?

Ok so mine is a tail of woe, a kodi reinstall lead to a library rescan and appears to have stirred the cobwebs on one of my disks and caused its demise, I woke up last saturday morning to a very unres...

Cheers, it's only climbed 14% in the last 4 days then it appears, anyone know if adding a new disk before this completes would be problematic or would help speed things up ?

The resync needs to complete before the system will process another disk.

So it's re-syncing with the bad drive? That could take a very long time, and likely will ultimately fail. Do you know which drive it is?

Hard to say if a bad drive is being resynced, or if the system is trying to resync a good drive, with the bad drive slowing the process down.

You can try smartctl -x on each of the drives - that could help identify which one is causing the problem.

  At this point what good would knowing which drive was bad do ? I've gotta wait till the current sync operation has complete before performing a physical swap haven't I ? It's using xraid across all current drives, I can see serial numbers from the log earlier in the week that indicate which one but also one of the bay lights is constantly flashing

    When the NAS resyncs a drive, it is reconstructing its contents from the others.
    
    If it is resyncing the bad drive, then you could just pull it. The resync would fail, and you could then hot-insert a good replacement.
    
    But if it is resyncing a different drive, then pulling the failing one would cause the volume to fail (losing your data). So the best strategy there is to wait and hope it completes successfully before the drive totally fails.
