UPDATE:
I completely understand frustration, and you can't imagine how was I frustrated in a monring. Have no idea why I was given with some many challenges from beginning, but will try to stay professional and the update as following.
Currently machine is being restored on backup disk, once it is done I will bring it up on backup disks, they are slower, but should not be an impact for end user.
Meanwhile we will be back online, I will prepare spare disks in main array and will prepare system to boot there. And will swap later to production machine
The state we will restore will be time of crash, which is 8hours ago.
Thanks for the response, i guess its a hard time now, i just have one question because im not near to my mining stuff. Does it mean that the last 8 hours of mining are lost?
Stratums servers were offline, so you minings rigs either switched to another pools, or were just idling as mine (low electricty)
