Am reasamblat aria ca /dev/md0 . La inceput nu a vrut sa adauge si
/dev/sda1 , cu --readd nu a vrut cu --add l-a adaugat si acum ii face
rebuilding
[root@datavault ~]# mdadm /dev/md0 --add /dev/sda1
mdadm: added /dev/sda1
[root@datavault ~]# mdadm -D /dev/md0

La serverul meu de fisiere de acasa mi-a picat sursa . Pana sa ma
prind ca e sursa de vina , facea probleme cand erau toate hdd
alimentate , s-a dus si centos 6.9 care dadea kernel panic not
tainted. Cu ocazia asta am reinstalat cu un centos 7.4
treaba e ca acum raid-ul fost /dev/md127 a devenit inactiv :

la examinare pe fiecare disc in parte datele par a fi ok dar aria nu
pleaca din cauza testelor facute . Trebuie sa recreez aria sau se
poate reporni ?
