I'm getting ready to upgrade a file server from RedHat 8, to RHEL 3.
The home and data disks are on an external RAID array, and they are on
an LVM (1.0.3) managed file system.
I don't have much experience with LVM so I'm a bit nervous about the
upgrade. I've read the LVM-Howto, but there is not much advice on OS
upgrades. Probably everything will go ok, but if I should lose the LVM
information, I'm asking what I need to know ahead of time, to recover
it.
vgdisplay -v shows two volumes /dev/sda and /dev/sdb on the array. I
think it's 2 volumes because of a maximum number of disks limit. The
two volumes are part of a single volume group, and a single logical
volume on top of that.
Should I vgexport before doing the upgrade? Any other hints would be
appreciated.
Thanks,
