Greetings Had some system issues and decided in the process of trying to repair things that I would rather use my SSD (/dev/sdd) for my operating system disk with the goal of improving performance. Up to this time the raid-10 array had been working as expected so there are/were no complaints nor issues. I don't know if many or any of you have installed your operating system on an SSD but this proves to be quite an interesting adventure, especially when its a UEFI system. Have finally gotten things so there is some semblance of order and wanted to start some items that had be left idle as I spent time trying to effect my system installation. It was at this point that I noticed that my Raid-10 array would not mount (in the past a simple click on the left hand column icon for the array would prompt a request for the root password to effect access (after booting only) and then access would be available until a subsequent reboot required the process to be repeated. At present I am not able to access the array. Details of commands tried are included in the following (which includes all of the necessary background data, I hope (please advise if more information is needed)). I chose not to attempt any --force actions without first asking for advice on this list. TIA for your assistance.
