Freshly installed OMV4 on USB stick; Added 2 drives after initial setup (3 total data hard drives installed) .All drives show up in "Disks" but only one of the new drives shows up in "file systems"
All drives are formatted as Ext4."
Create" gives me the option to format the drive, but as I have data on it I don't want to do this.
There are/is 2 TB of data on the 5TB drive,if I have to I suppose I could transfer the data off, then format then transfer the data back on, but I would rather not do this if I can avoid it.
Any help will be greatly appreciated.
I am running the latest stable release .. 4.1.19
hdd shows in disks but not in file systems

Have you used other filesystems on these drives before?
Like ZFS? -
yes , i used freenas with zfs for a few months, transferred the data off of them , wiped them then formatted to Ext 4 and reinstalled data. Why? does zfs leave something behind even though I wiped the disks?

Did you make a quick or a secure wipe? If the drive was used for ZFS earlier a secure wipe is the better choice.
Please look at this thread here: Raid management don't show all the drives -
Quick wipe, So i will transfer the data off and do a secure wipe thanks

Already done?

What is the easier way? I think a complete secure wipe is not absolutely essential. It should be sufficient enough to clear all old partition information with e.g. gparted or a similar tool, isn´t it? This should have the same effect.

Might be an option to use wipefs.
With wipefs -n you can see which signatures are on the drive. Then you can delete the signature which is causing the issue.Search the forum for wipefs -n /dev/sd

wipefs -n /dev/sd

Already transferred data and am wiping now.
I ran wipefs -n /dev/sdb on my data drive that is working and my output is:root@openmediavault:~# wipefs -n /dev/sdb

Does this indicate that there are still some zfs files on my disk?

No it indicates there is a residual zfs signature on the disk, quick wipe removes the one at the beginning but not the one at the end, that is why @macom suggested you run that.
Is there an easier way to remove the signature, yes, have a look here and here

With this signature OMV detects that this a member of a ZFS vdev. Therefore it is not shown under file systems. After removing this signature it should be shown again.
