Steps

• added virtual disks
• created fielsystems Gh1-Gh4 and mounted
• create iAmGh shares for all drives
• create oc- folders on Data  (admin, mdean, sdean, bobncarol, marma, tmp)
• moved all oc- folders to each Gh drive (to create possible landing zones)
• removed ownCloud samba share
• added samba shares for all oc-xxxx shares
• added Gh1-Gh4 to Greyhole pools
• modified mount_shares_locally to support www-data on oc-xxxx shares
• create link from the data share points to the same Gh1 share points
• added users for mdean, sdean, and bobncarol
• logged into owncloud with each user (creates owncloud folder)
• copied owncloud folder to Gh1 folders
• cp -Rp admin /media/06334345-6048-40aa-a206-ce471316d173/oc-admin
• Replaced orig folders with links to samba mounts
• rm -R marma/
• ln -s /mnt/samba/oc-mdean mdean
• mdean -> /mnt/samba/oc-mdean
• reboot
• added omv user back in and gave rights to all oc-xxx folders

ownCloud working (sortof)

data shares are links to the gh_ versions

You are mounting the CIFS share as root (because you used sudo), so you cannot write as normal user. If your Linux Distribution and its kernel are recent enough that you could mount the network share as a normal user (but under a folder that the user own), you will have the proper credentials to write file (e.g. mount the shared folder somewhere under your home directory, like for instance $HOME/netshare/. Obviously, you would need to create the folder before mounting it).

An alternative is to specify the user and group ID that the mounted network share should used, this would allow that particular user and potentially group to write to the share. Add the following options to your mount: uid=<user>,gid=<group> and replace <user> and <group> respectively by your own user and default group.

sudo mount -t cifs -o username=${USER},password=${PASSWORD},uid=<user>,gid=<group> //server-address/folder /mount/path/on/ubuntu

Can I move a single disk from one esxi to another esxi server?

Assuming that ESXi isn't installed on the disk in question, then yes, you should be able to simply install the disk in the new server. If you don't see it immediately, you may need to go to the Configuration tab for the host and choose "rescan" or "Add Storage". Of course, whatever you do, don't format the existing storage again, or you'll lose the data on it. You will probably have to browse the datastore and add the VMs you want to inventory, but it should be a pretty painless process.

System is setup using OMV  and Gh with 3 Gh drives.
Gh1 300Gig, Gh1 200Gig and Gh1 200Gig,
A Small 10 Gig filesystem with a single share called Data is used for the smb shares.

Soft links (ln -s) point to the Gh landing zones on Gh1 (Movies, Music, Photos,...)

ln -s /media/uuid(Gh)/Movies  /media/uuid(Data share)/Movies

ln -s /media/uuid(Gh)/Music  /media/uuid(Data share)/Music

ln -s /media/uuid(Gh)/Photos /media/uuid(Data share)/Photos

Test1) Remove Gh2 and see what happens...

[Seagate Barracuda ST2000DM001] NFS/NFS_3-000002.vmdk

can't be moved because it is inclued in snapshots (crap)

moved it to another Vitural Device Node (SCSI (0:9))

Everything worked fine... OMV moved it to /dev/sde1

Veeam Backup whole system

Restore to new location

remove snapshots of restored VM
