How to expand zpool?

[eastatom]

OS: FreeNAS-9.10.1-U4 (ec9a7d3)


I want to extend da1's data6t zfs volume.

The total capacity of ESXi is 8T, and the capacity allocated by freebsd-zfs is now 6.0T.

Gpart show - free - I want to extend 1.8T capacity to data6t.

I wonder how.

Please give zfs related command.

Hey mate,
Are you using RDMs or Hardware RAID?
If you are (which is sure at some point), please be advised that currently you are running your pool inside a FreeNAS VM without any redundancy and without following the virtualisation Best practices (link below).
That means that you almost certainly will have issues at some point, going from complete dataloss to uncorrectable filecorruption............

Good luck

I wonder how.

Simple. You don't.

ZFS does not like disks that mysteriously change size. The only way to expand a pool (without adding vdevs, of course) is to replace drives with larger ones. No clones, expanding drives or assorted bad ideas.
