Topic: problem booting from second raid mirror drive

[knaidoo]

Hi all,

I am trying to boot from my second mirror drive..I followed Darrel May's raid recovery howto and have raid working when I boot from primary drive but get the following error when I try to boot from second drive.  I changed the second drive from hdb to hda (slave to master) but when I boot I get LIL- and the system stalls.

Here is my info:

LILO version 21.4-4

Descriptor table couldn't be read (disk geometry mismatch?)

Here's a list of LILO errors & possible fixes:

Thanks Nick!  I solved the LIL_ problem by reinstalling Lilo:

"Reinstall LILO with /sbin/lilo. Tip:/sbin/lilo can provide a detailed log if you enhance verbosity and redirect the output to appropriate log files. To do so, proceed like this:
          /sbin/lilo -v -v -v >/boot/lilo.log 2>/boot/lilo.logerr  "

Now I can mirror my disks to my hearts content!
