Sure. You'll need (IIRC) a /boot partition on one disk, so put it on the 2.5 GB disk. You'll then have the option to set up your disks in linear append mode (largest possible partitions on all disks: 2.5+1+1=4.5 GB volume) or striped, which will require physical volumes of the same size and offers some performance benefit (equal size partitions: 1+1+1=3GB volume) or striped with parity, in which case you can lose one of the disks, and not lose any data (1+1+1parity=2 GB volume) > 1) Take out the failing drive and install the new drives. > 2) Install RH7.0 and use LVM to set up the disks (not sure how to do > that yet) > 3) After install completes add old hard drive as fourth drive. > 4) Mount old hard drive and "cp -a" the whole drive over the top of the > new drives that have LVM. That will probably work, if you have exactly the same set of packages installed on both the new and old installs... otherwise the rpm database won't be correct after the copy, and the upgrade may not work properly. > 5) Remove old drive and put CDROM back in. > 6) Boot on new drives containing all the old information. > 7) Upgrade to RH7.2 or 7.3. It would probably be easier to install 7.3 on the clean disks, and copy the data files to the new installation, but your plan could work. -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
