ReadyNAS NV+: how to remove not exists volume and disks (disk failed)
Hello all! My Dad asks me for help, but I don't know what was happened and what what should I do. He has a ReadyNAS NV+ with 4 disks without RAID (standalone disks). One of them has dead. I'd took ...
One option is to upgrade the NAS to the final firmware (4.1.16) if it isn't running that already, and then do a factory default procedure to rebuild the NAS from scratch. Off-load all the data first of course.
If you stick with flexraid, you'd need to install RAIDar 4.3.8 on PC to get the NAS into that mode. https://kb.netgear.com/20684/ReadyNAS-Downloads Also with flexraid and independent volumes, I recommend doing the factory default with only one disk in place, and adding the remaining disks later. That insures that you don't accidentally end up with RAID-1 or RAID-5.
If you plan on upgrading disks, you need to stick with drives that are no larger than 2 TB. NAS-purposed disks (Seagate Ironwolf or WDC Red) are good options. Don't bother with the HCL, it hasn't been updated for several years.
How many volumes is the system showing? If there is one for the dead (and removed) disk, have you tried deleting it?

So, what i've got:
- a disk with partition and data that NAS wants to reformat (I'd recovered the data to another location);
This one's odd for an NV+. You are saying this disk is healthy and was a working NAS volume?
Did you remove it, and try to reinsert it?
Is the NAS seeing the shares?
Thanks for your answer.
Yes, I'd tried to reinsert this HDD. NAS seeing it as a blank disk. The only one variant - to create a new volume.

Yes, the NAS is designed to treat insertions as a new disks.
You could try removing the disk, powering down, and then insert the disk (while powered down), and then reboot.
If that fails, I think you'll need to extract the data (I think R-linux for Windows will work) . https://www.r-studio.com/free-linux-recovery/ You'd connect the disk to a Windows PC with SATA or a USB adapter/dock. After you've offloaded the data, you'd create a fresh volume, recreate the shares, and restore data.
Thanks for the idea. I'd already recovered data using UFS Explorer. So this is not a big problem. More nerves: that NAS, shows lines with 2 old already removed disks and does not suggest adding a new volume to a new disk (when replacing a dead one). There is no way to remove non-existent volumes from the system settings.
