Disk replaced hot swap, resynced, volume degraded

Question

I replaced a disk drive with the exact same drive model.&nbsp; The NAS resynced the drive, but volume is still showing as degraded.&nbsp; Both drives show status as green. OS 6.6.1

StephenB · Answer

Download the logs and look in mdstat.log. &nbsp;See if the new drive is marked as a spare.

mlupo · Answer

There are no spare drives.&nbsp;Also, when I attempt to back up to the drive using Acronis, it gives me a network disconnected error.&nbsp; Using data files on ReadyNAS work fine without any network issues.

Any hint in mdstat on what the volume is degraded then?

Power light continues to blink as well, even though it has resynced.&nbsp; I have not tried balancing, defraging or scrubbing.
