I have 3x 4TB drives for a ZRAID1 config (single parity drive)
zpool create data zraid1 sdb sdc sdd
I have a volume that's 10.9T in size, which is what I would expect from a stripe configuration, not a RAID5 configuration. zpool status claims it is a raidz1-0 config (the 0 makes sense, this being the only pool on this machine).
Why is my size not 7.2T ?
Figured it out: zpool list shows total of the pool, not the resultant volume size. df -h shows that correctly as 7.2T.
