LVM certainly gives you lots of flexibility afterwards, however, that a straight partition won't have. > > And that brings up your original question.

However, it is quite a bit easier to backup your data, reformat, and restore. And it is likely to be faster; the only advantage to the LVM method is that you can do it with the system on-line. The LVM method would require two pvmoves. > > To see part of the details of what this would look like, see: http://fedorasolved.org/Members/zcat/shrink-lvm-for-new-partition > > Especially if you're not extremely familiar with the operation of LVM in this scenario. I have done similar, where I migrated the / filesystem from a single disk to a RAID6 set without data loss and while the system was live, but it required a lot of thought, careful planning, and lots of reading beforehand to make sure I wasn't missing something obvious. > > You could use a similar procedure to convert your disk to not using LVM (short version: reduce the LVM size, make a new partition large enough to contain all the data, clone the filesystem to the new partition, blow away LVM, make a new swap partition, resize the main data partition with gparted, all from a LiveCD of course), but, there again, backup/reformat/restore is probably quicker, and it is the only option if you have less than 50% free. > > It will be nice when gparted and similar tools get full LVM support; and, for all I know, some commercial tool out there has it already. > > Thank you very much for this.
