RAID 1 Issue - Volume Degraded after HDD replacement
I hava ReadyNAS 104 with firmware 6.6.1. Inside it I had 1 TB, 1TB, 3 TB and 6 TB HDDs, the two first configured as RAID 1. I had a RAID 1 with 2 HDD of 1TB, but one of them stop working. While ...
I would unslot sde and reinsert it. This should trigger a new resync attempt and hopefully end up cleaning the RAID array.
Otherwise, manually operation may be necessary.
You should also consider backing up your data.
I've already tried that. I'm trying to resync the raid using an 1 TB new HDD, but it seams that the result will be the same.
Thanks
PD: Backup information will be a little complicated because I use iSCSi on that volume.
After new resync, same status.

You should always have a backup of your (important) data.
Try to reboot the NAS.
While technically "easy" to fix with the appropriate knowledge and access to the machine, it's very difficult to advise you on what to do as it creates a responsibility, and performing this kind of operation blindly is very risky.
If you want to learn how to fix it, research online about "mdadm".
Otherwise, you can full backup + Factory Default + restore.
Or contact NETGEAR Support to see if they can help you (it will most likely be paid Support).
I agree with you about doing backup, but I don't see a easy way to do the iSCSI volume backup.
I've reboot the NAS multiples times, and the result is always the same, the second disk starts sync, past to online, but raid is still degraded because the second disk remains in spare status.
Thank you anyway
Can't you access the LUN from the client, and back it up from there?
