Upgrading capacity

[karl_w_w]

I currently have 3 x 3TB drives (6TB capacity) using X-Raid and I'm running out of space. My plan is to add a 6TB drive to give myself 3TB more total capacity, so that in the future I can replace one of the 3TB drives with another 6TB to increase total capacity by 3TB again.

Am I correct about these increases and does it seem like a sensible plan? Thanks.

Yes.  The capacity rule is "sum the disks and subtract the largest".

• 3x3 TB -> 9 TB - 3 TB = 6 TB volume size
• 3x3 TB + 6 TB -> 15 TB - 6 TB = 9 TB volume size
• 2x3 TB + 2x6 TB -> 18 TB - 6 TB = 12 TB volume size

It is sensible, though as you already know you'll need to wait a while to get the full benefit of the first 6 TB drive.

@karl_w_w, You might want to go here to explore on your own what you will get.
