Live ZFS resizing inside VMWare should be possible, but there are several steps:
– First you should resize your virtual disk in VMWare configuration. Recomendation is all virtual disks to be similar size for best performance in VMWare.
– Ideally VMWare should notify guest OS that resize happened. You should be able to see that with `diskinfo -v /dev/daX` command. If it didn’t happen – you’ll probably need to reboot at this point.

The new space will appear visible after partition 3 on each disk.
– Next you should resize your partition with `gpart resize …`. Hope it is the past one, otherwise this problem may have no easy solution. It should be doable for mounted filesystem. In my example commands are:
gpart resize -i 3 da0
gpart resize -i 3 da1
gpart resize -i 3 da2
– Next you should make ZFS to resize with `zpool online -e …`.
See output of `zpool status` command:
root@:~ # zpool status
pool: zroot
state: ONLINE
scan: scrub repaired 0 in 1h6m with 0 errors on Fri May 18 19:56:44 2018
config:NAME STATE READ WRITE CKSUM
zroot ONLINE 0 0 0
gpt/zfs0 ONLINE 0 0 0
gpt/zfs1 ONLINE 0 0 0
gpt/zfs2 ONLINE 0 0 0errors: No known data errors
So in the example you must execute following commands:
zpool online -e zroot gpt/zfs0
zpool online -e zroot gpt/zfs1
zpool online -e zroot gpt/zfs2
It’s good to execute `zpool scrub zroot`.
