https://discuss.linuxcontainers.org/t/how-to-resize-zfs-used-in-lxd/1333/9

Expand disk in Vsphere or qemu-img then

echo 1 | sudo tee /sys/class/block/sdb/device/rescan
sudo partprobe -s
sudo partprobe -s
sudo systemctl restart zed
sudo journalctl -f
zpool list
# it seems it does auto online resize these days

Older

echo 1 | sudo tee /sys/class/block/sdb/device/rescan

sudo partprobe -s
lsblk
zpool list
sudo zpool online -e <POOL NAME> <DEVICE NAME>
# zpool online -e mypoolname sdb
zpool list

# Note:
# partprobe - command to inform the OS of partition table changes

If you want autoexpand enabled

zpool get autoexpand zfspv-pool
zpool set autoexpand=on zfspv-pool

Other options that will probably work but test first

parted /dev/sdb rm 9
parted /dev/sdb resizepart 1 100%

Trash notes

echo 1 | sudo tee /sys/class/block/sdb/device/rescan
zpool get autoexpand zfspv-pool

sudo partprobe -s
sudo parted /dev/sdb rm 9
sudo parted /dev/sdb resizepart 1 100%
zpool status -v
sudo zpool online -e zfspv-pool sdb
