Hi,
I have set up raid1 for my system. I have a seperate hard disk for
root and boot, and two hds attached to promise ultra 66 - /dev/hde and
/dev/hdg. Their partitions are fd (raid autodetect)
on issuing mkraid, I get
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/hde1, 13312120kB, raid superblock at 13312000kB
disk 1: /dev/hdg1, 13312120kB, raid superblock at 13312000kB
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
Unfortunately there is nothing in syslog. My /proc/mdstat is
Personalities : [3 raid1]
read_ahead not set
md0 : inactive
md1 : inactive
md2 : inactive
md3 : inactive
On startup, I get
/dev/md0 invalid argument, /dev/md0 is not a RAID0 or LINEAR array.
I tried the following two raidtabs - both gave the same message. I've
attached my dmesg at the end.
Many thanks for any help
Dave
