Linux RAID help
Rick Getchell
I recently inherited a Linux server (RedHat 6.2, i386) that I know very
little about. Just today our UPS died and took down the whole farm with it,
including this unfamiliar server. When power was restored, this server began
to boot and failed when attempting to start RAID devices.
I have hardware RAID on some machines here and software RAID on some Sun
servers, but I've never done RAID in linux before, so I'm hoping someone can
give me a jumpstart. Meanwhile, I'll be poking around in the startup scripts
looking for something that starts RAID, then I hope to find out exactly how
RAID is supposed to work on this machine. Any suggestions would be
appreciated.
Here's what I see on the monitor at boot:
Welcome to Red Hat...; Press 'I'... interactive... yada...
Mounting proc filesystem [ OK ]
Configuring kernel parameters [ OK ]
Setting clock... [ OK ]
Activating swap partitions [ OK ]
Setting hostname... [ OK ]
Checking root filesystem [ OK ]
/dev/sda1: clean, 8439/193920 files, 27638/387560 blocks [ OK ]
Remounting root filesystem in read-write mode [ OK ]
Finding module dependencies [ OK ]
Starting up RAID devices: /dev/md0: Invalid argument
/dev/md0 in not a RAID0 or LINEAR array!
md0 md1 md2
*** Ann error occurred during the RAID startup
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D for normal startup):
