Is writing a null gpt sufficient? Hi Gene, You can ignore them, or not, as you like. If you want, you could overwrite them with zeros or a pattern of your choice; I would not bother. Logical volume creation and mkfs operations on the logical volume(s) will replace them.

(For instance, if I remember right, the entire logical volume would, in this case, wind up on the first-named physical volume vgcreate command.) The man pages for lvm and its subcommands offer a lot of options for things like storage allocation between/among multiple physical volumes that make up a volume group, the size of allocation units, such things as RAID level, and a large number of other properties. You probably know what you want, and from what I've seen on this list seem quite able to fish it up out of the man pages, some of which have usefully suggestive examples. >> >> OTOH, I would recommend ZFS for this based on experience with LVM and ZFS in both commercial (e. g., HP-UX and SolaRIS) and Linux environments. Both have learning curves that I would judge comparable, both are flexible and fairly easy to manage, and both are or can be highly resilient. On the whole, though, I prefer ZFS. >> >> Regards, >> Tom Dial >> >>>> >>> >>> How about to use debian-installer: burn the dvd image of Bookworm 12.2, put into the DVD drive then reboot the system.
