I'm trying to initisalise my raid array with mkraid /dev/md0, and heres what i get:
| Code: | cdimage root # mkraid --really-force /dev/md0
DESTROYING the contents of /dev/md0 in 5 seconds, Ctrl-C if unsure!
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sda2, 1961680kB, raid superblock at 1961600kB
disk 1: /dev/sdb1, 2061469kB, raid superblock at 2061376kB
disk 2: /dev/sdc1, 2061469kB, raid superblock at 2061376kB
disk 3: /dev/sdb1, 2061469kB, raid superblock at 2061376kB
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
cdimage root # cat /proc/mdstat
Personalities :
read_ahead not set
md0 : inactive scsi/host1/bus0/target2/lun0/part1[2] scsi/host1/bus0/target1/lun0/part1[1] scsi/host1/bus0/target0/lun0/part2[0]

Depends on which log package you are using. With the "original" syslog, it is at /var/log/messages. I think all of the logs are in /var/log -- kernel messages should show up with dmesg, of course. |

1. Post to the correct forum (Installation in this case)
2. Try Ctrl-Alt-F<1-4>. One of them is the syslog. |
