Thank you for your fast reply. Anyway, I really would like to use mirroring. Does anyone have suggestion in this topic? I don´t insist on LVM. I keep on searching different sites as well and I have found this idea, see below. Does it make sense? Please don´t forget I want to do it for root, boot, and swap too. What´s wrong with that? I think this is a very important feature that should be supported somehow without purchasing hardware. Regards, Ferenc Csuk

- create a md0 RAID1 device with your 2 disks (mirror, no use of LVM) - set the parttion ID to RAID autodetect (0xfd) - edit /etc/raidtab (see RAID Howto) - mkraid /dev/md0 - install LVM utilities (0.9.1beta3) - pvcreate /dev/md0 - vgcreate -n BGNAME /dev/md0 - lvcreate <some logical volume>

I just joined this mailing list, because I couldn´t find the solution for my problem.

I want to use LVM for the entire content of my SCSI disks in order to be able to do mirroring for the root, boot and swap partiotions too. (Simply I want to make sure that in case of hardisk failure I can replace with a good one, and reboot).

I installed Suse Linux 6.4 using 3 partition and then I followed the the instruction written in Chapter 19(converting root filesystem to LVM) of

I managed to complete until point 11 however, when I rebooted the system I got this error message:

VFS: Cannot open root device 3a:01 Unable to mount root fs on 3a:01

I don´t know where I made the mistake?

My questions:

1., Has anyone followed this instruction and finished succesfully? 2., Maybe I am on the wrong way, so could you recommend another solution for the above mentioned issue?

Mirroring? LVM will only supports RAID-0 (striping). I can't help you from experience since my / (root), /boot and swap partitions aren't part of the LVM - seems the safest option to me anyway. If I screw something up I can always boot linux init=/bin/sh rw and then do a /sbin/vgchange -a y.
