Reinstall - RAID still there, but can't access volume?????

So, my OMV install has been working for around 2 years, and suddenly stopped updating etc.
I decided this weekend to reinstall both of a my OMV's (I have 2), first one went well and is now operational, reinstalling was easy.
Second one however has now decided not to play ball

First, the system can see the RAID array (4x 2TB discs)
File system shows 2.9TiB out of 5.37TiB used, all good so far
I create a shared folder and then a share in SMB...................folder is shared but nothing is in it

Help is required and appreciated

Strange, individual shared folders are there now.
Problem solved
