Yes; this is mostly a user-interface issue. The current parted UI is not great in that it prompts for all sorts of irrelevant information when you are creating a partition on a label format that does not support or use that information. For e.g., this is what you'll see creating a partition on a GPT volume: (parted) mklabel gpt (parted) mkpart Partition type? [primary]? File system type? [ext2]? Start? 0 End? 100M (parted) p Disk geometry for /dev/mapper/t0-l0: 0.000-152.000 megabytes Disk label type: gpt Minor Start End Filesystem Name Flags 1 0.017 100.000 The whole primary/extended/logical distinction only matters for the MSDOS partition table format and the 2nd question (file system type) assumes that you want to put a file system on the device when you actually want to make it an LVM PV. > and what if i create an ext3 partition as a container for an lvm-PV - > am i required to set that lvm flag thingy within the partition table ? > or whatfor is that flag then ? Setting the LVM flag is the right thing to do; it will set the partition's UUID to be the LVM GPT UUID. This is a bit like the MSDOS type codes but for the GPT format. It shouldn't cause any problem to set this but, a bit like the MSDOS partition codes it's mainly documentation as few tools actually check GPT UUIDs (although looking at the anaconda sources it does appear to check/set this flag on the GPT volumes it creates and interprets).
