I have an Ready NAS 422 Firmware: 6.10.7 about 4 years old has been running with out issue for close to the entire four years - I recently stumbled across an error message on the Front LCD indicating that volume was degraded - and pulled the following from the warning log showing disk 2 was having sector issues as far back as 8/2/22
Aug 02, 2022 12:36:50 AM | Disk: Detected increasing reallocated sector count: [752] on disk 2 (Internal) [ST6000NE0023-2EX110 ZAD68VKN] 12 times in the past 30 days. This condition often indicates an impending failure. Be |
the error log also shows that the volume data health changed from redundant to Degraded
Aug 02, 2022 12:42:53 PM | Volume: Volume data health changed from Redundant to Degraded. |
then finally the disk 2 went from online to failed
Aug 02, 2022 12:42:54 PM | Disk: Disk in channel 2 (Internal) changed state from ONLINE to FAILED. |
I did not discover this until about Wednesday, September 21, 2022
I was in the middle of rewiring a PoE security system and let it go until I got the job finished two- three days ago. The NAS has continued to run and data is accessible, however with the drive in drive 2 throwing a failed error I am sure my redundancy is gone as disk to 2 is obviously bad. The DRIVES in the NAS are a pair of Seagate 6TB IronWolf Pro v11 7200RPM SATA 6Gb/s 256MB Cache 3.5-Inch NAS Hard Disk Drive (ST6000NE0023)'s In looking at the NAS control panel the diagrams ares as shown below
I must say I am a bit miffed as to why the one Graphic indicates RAID 1 and the Main Graphiv from the top left indicates X RAID but I digress I m not sure it matters of if it is in effect X RAID I really don't recall how I originally configured it .
I have ordered a replacement ST6000NE0023 to replace the failed disk 2 which appears by the graphic to be in slot 2 which I will confirm once I can get on a step ladder and open the Front Bay Cover to observe the LED's.
Biggest or most pertinent question is when I receive the new ST6000NE0023 can I simply remove the failed disk 2 ST6000NE0023 and Insert the new replacement ST6000NE0023 by doing a Hot Swap without Powering the NAS down then waiting for the new drive to be formatted and let the system configure and add it to the array ? Or do I need to power down the NAS , format the drive before adding inserting in the NAS and the power it on and let it do what ever auto configuration it needs to do . I am going to back up or copy the 1.37 TB of needed files /directories from the DATA Drive to an external USB drive before I begin the process as a precaution .
Can anyone confirm that I have the correct process outlined here and if I do not what I should do differently to achieve success ?
Thanks in advance to all who respond to help an old man figure this out

Personally, I test new drives in a PC before putting them in a NAS- in this case I'd use seatools, and run both the long non-destructive diagnostic and the full erase test.
Whether you do that or not, I recommend hot-swapping it. The NAS will then do a short drive test, format it, and then add it to the array.
Powering down and swapping it would also work. But hot-swapping has the advantage that the NAS sees the disk removal and insertion, so there is no need for it to figure out what is going on.

Netgear recommends doing a backup first (and I concur). If you don't have a regular backup plan in place for the NAS, I suggest taking care of that after you deal with the failed drive.

X-RAID is application software that Netgear layers on top of standard RAID. In your case, the system is set up to use RAID 1, and X-RAID is also enabled.
If X-RAID was not enabled, there would be no green stripe through the control.
