Expand a Zpool
Block storage volumes are very useful, they give me an easy way of getting ZFS on Ubuntu virtual servers or getting extra storage on FreeBSD. Just attach a volume and create a zpool.
Today one of my volumes ran out of space. So I logged in to my cloud provider and expanded it. Then to expand the zpool I ran the following command
# zpool online -e ZPOOL_NAME DEVICE zpool online -e tank da1
