[OpenIndiana-discuss] Seagate 3000GB Drive only shows 746GB

[George Wilson]

It looks like this disk has a Solaris VTOC on it so ZFS will only use 
the partition size that was manually created (or came shipped with the 
drive).

Can you try running 'zpool create <pool> <diskname_without_sliceinfo>'?

Example: zpool create test c4t0d0
