Hi, I have two hard disks:- ata1 - master = IBM 30Gig ATA100 (/dev/hda) ata2 - slave = IBM 30Gig ATA100 (/dev/hdb) Any ideas how I can software mirror these and use ReiserFS as a disk format? SuSE has to be bootable off either of the disks *and* if one drive blows up, I need to be able to swap it out with another one and rebuild the mirror pretty quickish. I dont need to hot-swap - powering down is fine. Can someone give us an idea where to start please! Cheers, - Chris.
Hi ! you could try using ReiserFS+LVM

Since I am lazy, I would just rsync them, after first partitioning the second drive of course. Then a crontab `rsync -a --delete /a /b` --for each partition--, as often as you wish, with a low priority nice value maybe, if needed. Switch drives and reboot. There are probably better ways ...

First off, don't use master and slave.... put the second drive on the secondary IDE channel as another master. You'll likely have better performance and no issues with detecting failures. If you are installing 7.3, it gives you the option of setting up the raid during the install. If you want both disks bootable, you have to play a few games with lilo to tell it that each disk is a boot device and re-run lilo for each. - Herman Chris.Smith@raytheon.co.uk wrote:
