+====4K sectors====
+For each device which will be made a part of the pool, a gnop "chained" device needs to be created, and then those devices need to be added to a pool:
+  gnop create -S 4096 /dev/da0
+  gnop create -S 4096 /dev/da1
+  zpool create data mirror /dev/da0.nop /dev/da1.nop
+This will create the "data" pool with the *.nop devices, making ZFS think the drives have 4K physical sectors. Next, the pool needs to be exported and the gnop devices removed:
+  zpool export data
+  gnop destroy /dev/da0.nop /dev/da1.nop
+Next, the pool can be imported from the "raw" devices:
+  zpool import data
+You can check the configuration of the pool by using the "zdb" command on the pool:
+  zdb -C data | grep ashift
+The ashift should be "12" for 4K alignment. This works because ZFS writes the ashift value in its metadata.

 Alternatively, you can have portupgrade prompt you before upgrading each port with this:
   portupgrade -ai
+or
+  In short, for upgrade just go to where you had installed plex (chroot, jail, jail in chroot...) and upgrade SW
+  pkg upgrade
 Afterwards, your ports, including Plex, should be up to date.

 I run the commands as root, so su preceding the following or log into the jail as root.

 Of course after it starts and you verify it runs properly you can remove the old folders and the tar/extracted copies. Now you are on the latest build with out having to wait for the plugin to be updated.
