Title:     mdadm, raid 1
Date:      Thu May  5 23:09:50 2011

Da se zaziva beze ztrat opravit raid1 tak, aby se mi po restartu sam nahodil?
Mam dve zrcadla, root fs na md0 ( / ) a md1 ( /DATA ). Md1 jsem delal rucne 
znovu pres 
# mdadm --create /dev/md1  --level=1 -n 2 /dev/sda3 /dev/sdb3

Vsechny oddlily jsou fd Linux raid autodetect.

Pole funguje, ale po restartu se nenahodi a musim dat rucne mdadm --assemble 
....

Co mi chybi? nejaky persistent superblock? 


Diky.
