Hi,
I did a command-line upgrade of a RHL73 server to Centos 5. It was a bit rocky road, but in the end it was successful.
There's one thing that bugged me. I'm using software RAID1 consisting of /dev/hd{a,c}. No LVM or anything fancy, a number of /dev/mdX partitions, including the root (+/boot).
I'd have preferred to continue using lilo as it works more easily with RAID1 root/boot setups. The deployment guide for Centos5 claims to support RAID1 boot partitions (RHEL4 didn't, and provided a pointer a site in UK which no longer works for more info), it's not clear how exactly a redundant boot block configuraton is achieved with that -- so that if you remove the primary drive, it'll still boot.
Anyone have pointers for this?
[I've gone through a number of sites with various hacks how to install grub on both disks, but I'm not quite sure which ones are valid, and whether those are needed anymore]
This has been touched on several times in the CentOS mailings. Did you also search CentOS? If not, ISTR that there are answers there. For grub, of course. <snip>
