Missing existing partitions

So figured i would share this experiences
I had updated from OMV 2.x to OMV 4.x via a fresh install.
OMV 2 was able see some existing partitions, but in OMV 4 the partitions where not being seen. After digging into things (and remember from way back) those partitions that were missing where from Hard drives that were part of an old zfs pool. I was able to confirm this by running "lsblk -f" where the FSTYPE indicated it was a member of a zfs pool. Luckily some of the disk i had in my NAS were never part of a pool so I mounted the old zfs pool disk via "mount -t xfs /dev/sdX1 /mnt/sdx1" then moved data off of said drives and ran "wipefs --all /dev/sdX" to remove the FSTYPE and created a new partitions.
