How to finish expanding a zfs filesystem?

UNIX for Beginners Q & A
1

I have a esxi 6.7 server running a Solaris 10 x86 vm (actually a bunch of them). The VM uses zfs for the pools (of course). I expand the underlying ESX logical disk, for example from 50GB to 100gb, then I set autoexpand=on <pool> that belongs to the esx logical disk.

what am i missing to finalize the expansion of the filesystem?
zpool list <pool> shows the expanded size of the disk, but the when mounted, the zfs filesystem is not expanded.
Do I need to set the reservation size for the filesystem? Right now, by default there is no reservations on the filesystem.

Can you show output of :

zpool list <zpool in question>
zfs list 
zfs get refquota,quota,refreservation,reservation <zfs file systems from list> # to check if reservations  or quotas are made.

Possibly you will need to increase the reservations and/or quota of the underlaying zfs filesystem to use the new space.

Now that you mentioned quota, i did go back and check the original expansion and found I did have to set a quota for the full amount.
