Re: replace x86 with x64 system and reuse existing LVM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I've done this now and the procedure is fairly easy and very safe. I did a 
test run with VMs first, of course.

You don't need to vgchange/vgexport etc. These changes do not carry over, 
anyway. A new system will find all volumes and make them active. But this 
doesn't matter.

For a kickstart installation you simply change the previously used disk 
config lines a bit, like this:

partition /boot --fstype ext3 --onpart=sda1
partition pv.2 --onpart=sda2
volgroup dom0 --noformat pv.2
logvol swap --name=swap --vgname=dom0 --noformat
logvol / --fstype ext3 --name=root --vgname=dom0 --useexisting

This reuses sda1 for /boot, sda2 for the volume group, an lv swap for swap 
without a reformat and an lv root for /, reformatting it. For an 
installation on real partitions only you use only the --onpart command.

Hope this helps someone in the future.
