Now with LVM, what do I do?
Pretty much exactly the same, if that's what you want. LVM is just a
layer of indirection that you place on top of *only* those partitions
you want LVM to control. It lets you create multiple "virtual"
partitions each of which includes one or more physical partitions. In
the minimal case, you can partition exactly as you would without LVM,
but make each of the Mageia partitions an LV formatted as ext4 (or
whatever) rather than a physical ext4.
The difference is that later on if you need to expand one of these 1-1
LVM partitions, all you do is create another physical partition
*somewhere* - either on that physical disk or another you add - and tell
LVM to make that new physical partition part of the LV you want to
expand. The original physical partition on which you based the LVM
stays exactly where it is without change, and the Logical Volume just
magically increases in size by the size of the new physical partition
you added.
Using LVM for some or all of Mageia has no effect on your ability to use
standard partitioning for other partitions on these disks.
It occurs to me that LVM (which I have only tested a long time ago)
would play nicely on a large disk with a gpt partition table.
Just divide the disk into a lot of reasonably-sized partitions (the
limit for a default gpt table is 128 (primary) partitions, and let LVM
combine them as appropriate, being dynamically reassociable as needed.
Then if you want to do a clean install of a new Mageia (or other)
release, could you just reformat the partitions you want (excluding
/home and whatever other partitions you want to keep), without problem
with LVM ?
If so, that would be nice.
The trick of course would be to ensure that you assign directories to
partitions in an appropriate manner.
some random thoughts ... :)
