Re: Raid 1 + lilo
Earlier in this thread, there was a question of how hardware RAID would
handle the failure of a drive on reboot. While at LinuxWorld I asked the
Intel team how their controller would handle it.
The answer was that the card would note the disk failure, notify you
of the problem, rebuild the array once you replaced the bad drive and
then the system would boot. Of course if you had a hot swap on line the
rebuild would be automatic.
It sounds like, for high availability with no hot swap, that software
RAID with LILO on both drives could be a better choice. Your system
would come back, although crippled, faster and be running while
rebuilding the array.
Seems from the discussions there is no "right" answer to which is
better. A lot of factors weigh in such as availability of a hot swap,
cost, availability vs. data integrity, etc.
