I renamed my HD's, Now Receive Errors - how to clean up old File Systems & Shares

So this is basically a fresh install of OMV. I did a few config changes, then decided I wanted to rename my HD's. I used Gparted to rename my drives, then when I rebooted the system, I noticed an unusual loading/error screen at the beginning about the drives. It booted up anyway, but no I have unnecessary info, I want to keep the system as clean as I can and do not want to start building junk files. examples below of what I want to remove

File System area - Media1 & Tatoonie were previously sdb1 & sdc1
(I found "dev disk by label (xxx)" in the /srv/ area when I ssh in, is it as simple as deleting those as root?)

Shared Folder area - Delete is greyed out

I also think my merge/union of the two new renamed drives failed - https://imgur.com/a/NijEX

How can I fix all of this?

Ok, Want to confirm before I make big changes to config.xml.... Can I delete this entire block?:

<mntent>
        <uuid>dd2736f6-9f3b-4944-84a6-44305cfbdf8b</uuid>
        <fsname>/dev/disk/by-label/tatooine</fsname>
        <dir>/srv/dev-disk-by-label-tatooine</dir>
        <type>ext4</type>
        <opts>defaults,nofail,user_xattr,noexec,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0,acl</opts>
        <freq>0</freq>
        <passno>2</passno>
        <hidden>0</hidden>
      </mntent>

I put my big boy pants on (and was impatient, not fully live anyway) and followed thru with what I said above. Additionally, I also had to find the uuid and remove them from the <sharedfolder> area.

Thanks! I have cleaned out the unnecessary clutter. Settings changes continue!
