Suggestion for x-raid3
This is a suggestion for a hopefully smarter utilization of disks-arrays of disks of different sizes. Say that I have 3 disks of 1 TB each. I buy a 3 TB disk and put it into the empty slot, after s...
X-RAID2 is fine. Not even sure if what you want is possible. X-RAID2 uses standard RAID levels (good for recovery of data using a x86 linux box if needed as a last resort).
Take your first example. 3x1TB + 1x3TB. You'll get a volume of 3TB (before overheads, measurement discrepancy etc.).
Take your second example. With 2x3TB disks the volume will utilise the full capacity of the 3TB disks. X-RAID2 is redundant RAID. With one 3TB disk there was nowhere to have a redundant copy of 2TB of the data on the disk. But with two there is. So the volume will expand to 5TB (before overheads, measurement discrepancy etc.). After the resync completes a reboot or two may be needed before vertical expansion takes place (wait 5-10 minutes between each reboot).
