O seguinte me confunde:
[root@mrak ~]# mdadm --examine --scan
ARRAY /dev/md/0 metadata=1.2 UUID=d3f800db:26de8691:dc0caf45:0f75028b name=mrak.dex.internal:0
ARRAY /dev/md/0 metadata=1.2 UUID=1870fd84:2234e3d4:580f7634:b0b621e7 name=mrak.dex.internal:0
Este array é RAID10, compreendendo 4 discos Seagate Momentus XT 750GB. O UUID do RAID ativo é d3f800db: 26de8691: dc0caf45: 0f75028b. Alguém pode me explicar por que estou recebendo a segunda linha ARRAY?
Além disso, por que eu não vejo / dev / sdb1, / dev / sde1 e / dev / sde1? Essas são todas partições usadas para construir o array, que são do tipo "Autodetect do Linux Raid".
Se obtiver detalhes de / dev / md / 0, obtenho:
[root@mrak ~]# mdadm --detail /dev/md/0
