Answer 1

31 seconds of video - out of sync in the raid.
Press Ctrl-C at about this boot location, there will be a raid adapter menu, see what's going on there in more detail.
Theoretically, he himself should be synchronized as a result. Somewhere there in the menu should be shown the percentage of synchronization. Probably at you a mirror from two disks.
True, usually the disks are still available, although they work more slowly and there is no fault tolerance.
If you do not know what raid and raid adapters are, then it is better to call a specialist.

Answer 2

Did he always catch an overhit with you, or only after the light had started to cut?
