Hi
I have a QNAP TS-859 Pro+ whose status is unmounted. It was working reasonably well until recently – even after I had to change one of the 3.0TB drives with a suitable replacement. However, now it is showing as in a unmounted state. I read your article How to Fix Unmounted Raid but could not discern whether your instructions would be suitable for my model which has eight drives on a raid 5 setup. Any help would be appreciated.
Regards
David Crook

Else, probably you can solve this with this document;
