Un RAID1 s-a spart, unul dintre device-uri a fost "removed" automat, nu stiu
din ce motive, nu cred ca e hardware, dar am dat un badblocks pe el si
ruleaza acum.
Cum bag inapoi device-ul in RAID1? Am incercat asa:
mdadm /dev/md1 --add /dev/hdg2
Dar mi-l face "spare", iar ala "removed" nu dispare de acolo.
Nu am mai avut nevoie de mdadm pana acum si nu prea e momentul sa bulesc ceva.
Multumesc anticipat pentru ajutor.
Asa arata:
mdadm --detail /dev/md1

in mod normal dupa mdadm -a /dev/hdg2 ar trebui ca la --detail sa obtii
cam asa ceva (testat acum 30 de sec):[EMAIL PROTECTED] ~]# mdadm /dev/md0 -f

mdadm: set /dev/hdj1 faulty in /dev/md0

Cheia e acel " State : clean, degraded, recovering " care dispare dupa
ce mirrorul se reface.
