ReadyNAS NV+ Stuck on Booting

Hi

Well after a brief pause to get the right cables etc to arrive so I could get the 4 drives in to another Ubuntu server everything's looking promising... although puzzling :-)

So I now have the existing 4 drive array mounted under standard Ubuntu.  No drive errors that I can see.

(command line walk through and details below)

So The drives look ok. Mount ok.  I'm still none the wiser about why the redynas wont go past " Checking FS ..."

Dare I ask; "Next suggestion?"

Mark

For the benefit of furture visitors and diagnostics sake;

OS is Ubuntu Workstation v16.10

SDA = Existing Boot drive

SDB to SDE = Drives 1 (left) to 4 (right) from ReadyNAS NV+

From root / sudo user;

# apt-get install fuseext2 lvm2 smart

**** reboot ****

**** check the smart status again, previously was via USB not direct attach ***

*** All looks ok there, lets see what the partitions look like ***
