ReadyNAS Issues with startup
Hi, my Ready NAS Duo with 2x2TB disks is gettign a bit old. Yesterday, after a power outage the unit rebooted and went into RAID Sync. When it finished I could not see the NAS on my network, nor coul...
The next step is to back up the data - especially if disk 2 is also fairly old.
Once that is taken care of, you can hot-insert a new disk 1. After that resyncs, everything will be back to normal.

They are on the HCL, but the Barracuda drives don't have a good reputation reliability in RAID arrays. The 3 TB drive seems particularly trouble-prone, so it's possible that the other drives in the family don't deserve that reputation. Once you have a backup, there's no reason not to use the Barracuda you already have.
Though generally I recommend NAS-purposed drives (WDC Red or Seagate Ironwolf) or (if more performance is needed) enterprise class. I use mostly WDC Reds myself. I have a duo v1, it has a WD20EFZX ( 2 TB Red) and an older Seagte (I don't recall the model off-hand).
Is it worth trying an OS reinstall form the Boot Menu? Is there a risk that I might lose data doing this? I guess I coould remove 1 disk and keep it aside.
An OS-reinstall is generally safe, but I don't think it will help. There are some situations (particularly a full OS partition) where it can make things worse.
I suggest powering down the NAS and removing disk 1. Power up, and see if it boots normally (with file access). If that fails, then power down again, and try this test with only disk 2 in place (in slot 2, don't move it to slot 1).
If either of these works, then the next step is to offload the data. Don't try reinserting the missing disk. The fastest way to offload is to copy the data to a PC that is connected with ethernet.
Then I'd recommend testing both disks in a Windows PC, using vendor tools (Seatools for Seagate, Lifeguard for Western Digital).
Not sure I follow. If I remove Disk 1 and power up, only Disk 2 will be in the drive.
Did you mean to replace disk 1, remove Disk 2 and reboot?

No. I meant remove disk 1, and power up with only disk 2 in the drive (leaving slot 1 empty). With XRAID or RAID-1, the system should boot. The volume status is degraded, since there is no RAID redundancy. But the system normally will boot and give you access to the files, so you can off-load the data. It can't resync, because there is nothing to sync to.
Similarly, the second part was to boot the system with disk 1 in slot 1, and slot 2 empty.
It's very important to do the disk manipulation with the NAS powered down. If you hot-insert a disk in your NAS, the system will attempt to format it, and then do a resync. We don't want that.
Hi StephenB, I powered down, took out Disk 1 and rebooted. After a long volume scan I have now regained access to my device and data, albeit on one drive. Disk 1 slot is currently empty.
The old Disk 1 is a WD20EARS that I've had in the machine since new. Must be 8 or 9 years old.
What do you recommend as next step? I have an unused HCL approved spare HDD ST2000DM001 sitting around. This is the same as the disk in the ReadyNAS.
Thank you for your great guidance so far. Really appreciate it.
