[rhn-users] Software RAID 1 recovery - Primary/master dead

[Jesse Espinoza]

Problem solved.

 

Just in case anyone ever runs into the same problem. I found the following
RAID How to that got me going:

http://www.tldp.org/HOWTO/Software-RAID-HOWTO.html 

 

Section 7.3 allowed be to make secondary drive bootable. The 'device'
command like the notes state failed on RHEL ES3 but the root and setup
commands worked followed by a reboot. Then the system started normally.

 

grub
grub>root (hd0,0)       
grub>setup (hd0)
grub>reboot

Folks,

 

I need some assistance getting our secondary/slave drive to mount and
startup. It's originally setup with RAID 1 configuration running Red Hat
Enterprise 3 ES. Both drives are IDE configured as md0=/boot md1=swap and
md2=/.

 

We had a power outage that killed our master drive, it doesn't boot or
startup. Our slave drive seems to be ok, so we made it the master drive. Now
all I get on the secondary drive when it boots up is a grub configuration.

 

I've searched everywhere on how-to recover when losing the master drive but
found very little help. It seems like I need to re-configure the mbr record
for the secondary drive. Could anyone point me to the right direction?

 

Thanks, 

 

Jesse
