Help needed with Readynas212
Hi! I received an alert my volume was degraded (Disk #2). It then told me: Detected increasing reallocated sector count: [606] on disk 2 (Internal) [WDC WD60EFRX-68L0BN1 WD-WX21D5533R6R] 32 times in...

thanks StephenB and MikeD1234 . So now I've backed up the data from my 6TB to the new 10TB drive. Can someone please walk me through the next steps?
Just to be clear, I am assuming that you connected the 10 TB drive to a PC (windows or mac), and backed up the data on the NAS over the network. If you didn't do that, let us know the details, as the steps below might not be correct.
(a) hot-insert the blank 10 TB drive into the NAS, and wait for it to sync.
If the sync is successful, then
(b) remove the 6 TB drive. Hot-insert the other 10 TB drive and format it in the NAS. It will resync and expand the volume to 10 TB.
if the sync fails, then
(c) remove the 6 TB drive and do a factory default with the blank 10 TB drive in place
(d) reconfigure the NAS (recreating shares etc)
(e) copy the files from your current 10 TB drive
(f) hot-insert the current 10 TB drive into the NAS, select it, and format it. It will then sync with the first drive.
Note if you like, you can skip (a) and (b), and instead just do steps (c)-(f). More work, but you would get a completely clean volume and OS partition.

Once I get my 2nd 10TB drive, do I just take out the 6TB, and insert both 10TB (one has my data, and the other would be the new blank one)?
No, that won't work. So don't try that.
MikeD1234 If he was using RAID0, the loss of a drive would not have caused the volume to be degraded, it would have been dead. While he said that it said the degraded volume was due to drive 2, maybe it really was drive 1 that caused the NAS to become degraded and the warnings about drive 2 are on top of that. The logs will be of help there.
ummjay Did you inadvertently pull drive 1 and then return it, with power on, during the process of removing drive 2? With power off, please try pulling Drive 1 and putting Drive 2 back in (in bay 2) and then power up and see what you get. If your volume is then accessible, you need to back up your files ASAP. DO NOT add a drive 1, as that will kick of a sync, which is very intensive on both drives, and may cause drive 2 to completely fail.
Sandshark been a while since I worked on RN units.
But, yes, that's what I meant, if he was already experiencing issues with the disk that was still "active", and he ejected it or the wrong one.. We don't really know unless we see the logs, and check how the volume was created, and, what the BTRFS logs say...
Probably not raid0 though, most likely raid1, with two broken disks..
Maybe he can get it up in RO, if one disk is still fine, or, at least readable.
If you can share your logs ummjay.

MikeD1234 , an RN212 is a 2-bay unit. So not RAID5. That's why I told him to try just the other drive, he undoubtedly had RAID1.
