I downloaded joyent's smartOS vmware image and got that running. Now I would like to increase the size of /opt because they were pretty stingy with it in the vm.

In the vm's settings, I expanded the disk to 35Gb. But I don't know how to grow the zfs volume from inside smartos.

If this is not possible, is it possible to create new smartos zones on disks other than the /opt filesystem?

Check, that you have backup (not zfs @snapshot).

Then you need to expand disk label via interactive format util.

If you have already done this, then you could expand ZFS pool.

How to expand ZFS pool.

get pool name

# zpool list

get all possible settings for pool

# zpool get all PoolName
....
PoolName  autoexpand     off                         default
....

set autoexpand option to 'on'

# zpool set autoexpand=on PoolName

ZFS pool will grow at this moment, you will see it in

# zpool list

To see size of opt dataset you may use command

# zfs list

If opt will not grow, then check its quota and edit it via set:

# zfs get quota

Return option to previous state

# zpool set autoexpand=off PoolName

    My answer is based on my experience with SPARC Solaris with ZFS and searching some base information about smartos on their site smartos.org (i found info about `format` on it). So i have not deal with smartos, but it should work i think. – Sasha Golikov Jun 07 '18 at 07:07
