ZFS Storage Size Reported in GUI & CLI

[masteryoda]

I have a freshly formatted set of 4 1TB disks in RaidZ2. the GUI under node->Disks->ZFS shows 4.09TB, while the node->local-zfs->Summary shows 1.92TB.





Here's output of zpool list

#zpool list

NAME           SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOT
local-zfs     3.72T   157G  3.57T        -         -     0%     4%  1.00x    ONLINE  -

Can someone please explain why i see 50% less storage ?

Well, "Disks" discussed physical devices - and you have given 4*1=4 TB to ZFS.

"local-zfs" shows usable space and a RaidZ2 uses two devices for redundancy, so (less than) half of the raw value is shown.

Looks okay...
