I get the following message after doing mkraid /dev/md0
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sda1, 24066kB, raid superblock at 24000kB
/dev/sda1 is mounted
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
I am a little confused about how to set up raid1.
I want to mirror /dev/sda to /dev/sdb (two 9 gig SCSI disks)
The example says to have raidtab say /dev/sda1 and /dev/sdb1
Does this mirror the whole disk, or just the partitions?
Should /dev/sdb already have partitions or should it just be a raw disk?
Does /dev/sdb need to be in fstab?
Lost in Linux,
