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.
Are you using X-RAID?
Have you downloaded the log zip file?
Also, do you have a backup of the data?
Thanks for your response. Yes i'm on XRAID, No I don't have a backup of the data. I was hoping my 2 hard drives would be a mirror of each other and as a result, backing up the data.

Although RAID redundancy is helpful, it is not enough to keep your data safe.

I then put my right disc back in, and that was an issue... I guess I misread the above, as it started to sync. Once I noticed that, I quickly shut down the unit. I then took out the left disc, and put the right back in, and turned back on.
It was very important to power down the NAS, and remove the left disk first. That would have prevented the resync.
You could try again with only the left disk inserted. Though I am guessing that also won't work.
If it does fail, then you will need to try RAID recovery software in a Windows PC. You'll need to connect at least one of the disks either with SATA or with USB adapter/docks (there are several that have 2 slots). You'll need RAID recovery software that supports BTRFS. ReclaiMe is one package that folks here have used with success. You'll need the Ultimate version (about $200). Note you can download it first, and see if it can recovery anything prior to purchase.
