RN104 Resync Speed on 3rd Drive Replacement Very Slow
I am updating my RN104 from 4 8Tb drives to 4 10Tb drives. After replacing the first drive, the resync took a couple of days to complete. After replacing the second drive, about the same length of ...
I rebooted the NAS and the resync speed increased to about 14 Mb/sec. I don't know what was causing the slow down before.
I do have backup jobs running Rsync. This particular NAS does not have any backups configured on it, but it is the NAS that recieves backups from another NAS.

I have not set anything on my router that would have to do with any of my NAS's. In fact, I don't remember setting anything except the basic out-of-the-box settings. I agree it is concerning. I updated my passwords to be safe.
