Question re: re-establishment of a raid-10 array

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

Dee
