criar raid5 via software usando mdadm
Olá a todos,
Estou com problemas ao criar o raid5 usando mdadm, consigo criar
sincroniza direitinho, formato com reiserfs, monto e faço gravações
porém quando dou um boot, dá um erro de superblock not found do reiserfs
e só pressonando CTRL+D para passar e o raid não é montado.
Segue o que fiz após montar as partiçoes do tipo de raid autodetect (FD)
comando para criar
mdadm --create /dev/md0 --chunk 64 --level 5 --raid-devices 3
--spare-devices 0 /dev/hdb1 /dev/hdc1 /dev/hdd1
mdadm: /dev/hdb1 appears to be part of a raid array:
level=5 devices=3 ctime=Mon Jul 18 18:59:38 2005
mdadm: /dev/hdc1 appears to be part of a raid array:
level=5 devices=3 ctime=Mon Jul 18 18:59:38 2005
mdadm: /dev/hdd1 appears to be part of a raid array:
level=5 devices=3 ctime=Mon Jul 18 18:59:38 2005
Continue creating array? y
mdadm: array /dev/md0 started.
