How to save data on RAID 10 array after something happened to OS (RAID 10 wasn't used like OS)
SITUATION
I have a machine that works on Ubuntu Server 16.04. I managed disk space in the following way:
And then, created two RAID 0 arrays this way:
After installation I added 6 more disks and created RAID 10 with 2 copies (near location).
PROBLEM
One time I made a lot of changes in settings. After that I rebooted the server and I got the following error:
So, something happened to the RAID array that was used for swap. And, that means that Ubuntu can't boot.
But I want to save data that was on the RAID 10 made of 6 disks.
QUESTIONS
Is it possible to fix that error with the swap?
If no, is it possible to just install OS again but use the data that is being stored on RAID 10 array? If yes, then how to do that?
