*** Do this on UGB (NSF) ***

0. stop samba and NFS

1. rsync data to uga (nsb)
 root@nsf:~$ rsync -avh --progress --delete /export/ug/ root@nsb:/export/ugb/

2. umount /export/ug  umount /export/ug1
3. recreate vdisks
	x) PATH=$PATH:/opt/dell/srvadmin/bin
	
	a) check controller's disks 
		omreport storage pdisk controller=0 | grep -E '^(ID|Status|Capacity|Sector Size|Bus|Power|Media)'
	
	b) delete old vdisk
		omreport storage vdisk controller=0 | grep -E '^(ID|Name)'
		omconfig storage vdisk action=deletevdisk controller=0 vdisk=six
		
	b) create disks
		omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:6 writepolicy=fwb name=disk06
		
		root@nsf:/$ omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:2 writepolicy=fwb name=disk01
		Command successful!
		root@nsf:/$ omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:3 writepolicy=fwb name=disk02
		Command successful!
		root@nsf:/$ omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:4 writepolicy=fwb name=disk03
		Command successful!
		root@nsf:/$ omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:5 writepolicy=fwb name=disk04
		Command successful!
		root@nsf:/$ omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:6 writepolicy=fwb name=disk05
		Command successful!
		root@nsf:/$ omconfig storage controller controller=0 action=createvdisk raid=r0 size=max pdisk=0:1:7 writepolicy=fwb name=disk06
		Command successful!

		
		fdisk each disk,
		u
		2048 start 
		sdc sdd
		sde sdf
		sdg sdh
		
4. create zfs pool. 3x mirrors
	zpool create -f ugb mirror /dev/disk/by-id... ... mirror ... ... mirror ... ...
	
	`zpool status` should look like:
	    uga                                               ONLINE       0     0     0
          mirror-0                                        ONLINE       0     0     0
            scsi-36848f690ec946a001f4604200a61a9c4-part1  ONLINE       0     0     0
            scsi-36848f690ec946a001f46042f0b49a2bb-part1  ONLINE       0     0     0
          mirror-1                                        ONLINE       0     0     0
            scsi-36848f690ec946a001f4604460ca4d664-part1  ONLINE       0     0     0
            scsi-36848f690ec946a001f46043c0c144593-part1  ONLINE       0     0     0
          mirror-2                                        ONLINE       0     0     0
            scsi-36848f690ec946a001f4604520d5ff888-part1  ONLINE       0     0     0
            scsi-36848f690ec946a001f46045c0df837ce-part1  ONLINE       0     0     0

			
5. create the pool with the compress option
	zfs create -o compress=lz4 ugb/ugb
	
	zfs set mountpoint=/export ugb
	zfs set compression=lz4 ugb
	zfs set exec=off ugb


5. zfs import from uga(nsb) to ugb(nfs)

	uga (nsb)# zfs snapshot -r uga/ugb@transfer
	uga (nsb)# zfs send -R uga/ugb@transfer | ssh ugb (nsf) "zfs recv -vFd ugb"
	
	
	rename ugb/ugb to ugb/ug
	
	enable sharenfs, otherwise nested mounts don't work (WTF?)
	zfs set sharenfs=on ugb
	
	
6. Ensure zfs gets mounted properly on reboot
