Readynas Duo constantly resynching volume
Readynas Duo RND2000 v1, the act light is constantly active, so upon checking the logs i find that the device appears to continually find and fix errors on volume C then a resync begins that takes ma...
Try (with power off) removing and re-seating the drives. That can also happen if one drive wakes from sleep much slower than the other. Is one drive a "green" one and the other not? Try disabling drive spin-down (if it is currently enabled) and see if that makes a difference. Unfortunately, that can also be a sign of a failing unit, possibly just the power supply, but equally or more likely something else.
Hi thanks for your reply, I actually swapped both drives in the end as they are both 10 years old. Having done so I run diagnostics on them outside of the nas environment and one showed a smart spin retry failure, so as you say it was probably due to spin up. Not sure why the smart spin retry didn’t show itself in the nas smart data readout.
"Smart Spin Retry" is not common to all drives. It also is typically an indication that the drive is a "green" one, and that type of problem is precisely why green drives are not recommended for NAS use, especially when used together with those that are not "green". When only one drive automatically spins down for power savings, the slowness in spinning back up can disrupt RAID integrity.
- Thanks for the info, it’s good to learn more about this and you obviously know your stuff. I’ve replaced both drives in the nas with seagate ironwolf models, specifically for nas. Although having said that, the deskstars lasted a decade so didn’t do bad at all.
Another problem I’ve never seemed to be able to overcome on this model is remote connectivity, I’ve followed guides and even had netgear support during the early period of having this unit but it refuses to communicate with anything the other side of the firewall. Just wondered if you had any experience in this area and knew of any magical fix with port settings etc?

So you do need to be careful here.
It is possible to access the NAS remotely using FTP/FTPS. With the Duo v1, you can't enforce FTPS (encryption), but if you can set up the FileZilla (or WinSCP) client address book to always use FTPS. If you think that would work, I can walk you through the firewall settings.
You don't want to forward SMB 1 - that is a really bad idea (and a lot of ISPs would block it). I wouldn't forward HTTP, since it risks exposing the NAS admin web interface.
