I will look into it.. I also went to the sistina page and read that I need to execute some script called devmap_mknod.sh. I can't seem to locate these scripts. I already have lvm and lvm2 installed. and it seems when I run dmsetup, it tells me it can't locate /dev/mapper/control. (Me thinks it needs the devmap_mknod.sh file) > I did install FC1 with Software Raid 5 and LVM on top of it, but doing so on less >than three physical disks results to up to 5 times slower transfer (because of the >raid).

With >ext3 it worked, but fsck.ext3 had a lot of work to do (the partition was ~50G full). >I hope one day online resize will work with bouth and reiserfs will get more stable >with acl and SELinux support. > http://www.aplawrence.com/Linux/lvm.html > ps: putting the /boot partiton ouside the LVM worked fine for me. Actually for me, this is a notebook and I just want some simple things. I heard of Lvm and I want to make it such tat it's less painful for me to move/resize partitions around whenever one gets full. I don't want to keep running qt_parted and having to reboot the machine and what not. Esp if it's my root partition and then grub's gonna complain. :-(
