Доброго времени суток линуксоиды!
1. Развалился RAID0, причем при загрузке с LIVECD raid0 видится и прекрасно монтируется, только не монтируется в системе.
2. И раньше были названы по человечески md0, md1..
сейчас md122, md123...

что делать? получается его нет как девайса, виновата ли в этом конфигурация mdadm.conf хотя в нем было ранее вписано вместо md127 -> md5
