How do I add a second 10 tb disk on my ReadyNas 214
Hi all. Im planning on adding another 10TB Seagate Ironwolf disk to my ReadyNas 214 as the currently installed similar disk (10TB Seagate Ironwolf) is almost full. For the benefit of those not familiar with the ReadyNas 214, it has 4 disk bays and total storage capacity of 24 TB. My question is which bay do I install the 2nd drive, and does it matter which slot it goes into. I'm not really bothered about backing up as I have that already taken care of externally. Please bear with me, I'm technically challenged. Thanks.
So does it mean that XRAID will mirror the equivalent of its capacity on the second hard drive.(Please correct me if I'm wrong).
Yes. Inserting another 10 TB drive in XRAID mode will result in RAID-1 volume - which is mirrored disks. Adding a second 10 TB drive in XRAID mode will convert the volume to RAID-5.

The datasheets for ReadyNAS uses the largest compatible disks at the time the product is launched, and generally aren't updated later. In the case of the RN214, that was 6 TB.
The largest compatible disks for the RN214 are two 16 TB Seagate IronWolf/IronWolf Pro models. So if the datasheet was updated, it would show a 64 TB capacity. There is no known limit to the actual disk size, but sync times do become much longer when use bigger disks.

The first thing to understand is that if you want RAID protection, then adding a second disk will not increase the capacity. You'd need to add 2 disks in order to do that.
The formula for capacity with XRAID is "sum the disks and subtract the largest". That extra space is used for RAID recovery blocks. That gives you protection from routine disk failures. It also makes it possible to easily "vertically expand" the volume later on (upgrading at least two of the 10 TB drives to a larger size - for instance 16 TB).
If you do want RAID redundancy than you
hot insert the first new drive
wait for the resync to complete
hot insert the second new drive
wait for resync to complete
At that point you'd have a 20 TB volume (~18.2 TiB).
But if you can only afford one disk right now (or don't care about RAID protection), then you need to switch to FlexRAID. The best approach is to create a second volume with the new disk, and to shift some shares over to it. Generally you want at least 15% free space with BTRFS. So you'd
switch to FlexRAID by clicking on the XRAID control on the volume tab. (if there is a green stripe on that control, then XRAID is enabled).
hot insert the new drive
select the drive from the graphic on the volume tab
create a new JBOD volume
At that point you'd have two 10 TB volumes (~9.1 TiB).

I shall be going with the FlexRAID option as it's a cheaper option for me. Like I said earlier, I've got my data backed up externally somewhere, so I'm safe in that respect.Anyway, thank you for taking your time to break it down for me and making it easy to understand, you've been a massive help. I really appreciate that. God bless.
