I want to create a LVM partition using the parted command. So far I did:

# set up the partition table
parted /dev/sda mklabel msdos

#/dev/sda1 (boot) :
parted /dev/sda mkpart primary ext2 1MiB 513MiB

#/dev/sda2 (LVM) :
parted /dev/sda mkpart extended 513MiB 100%

# set up partitions' flags
parted /dev/sda set 1 boot on
parted /dev/sda set 2 lvm on

But I get a "W95 Ext'd (LBA)" partition (type f), see fdisk -l output. I would like a "Linux LVM" partition (type 8e).

How can I force the partition ID using the parted command? .

The type on an extended partition MUST be 0F. You can't directly use the extended partition as an LVM PV. Instead, you need to make an extended partition, then make a logical partition inside the extended partition. The parted manual has an example of how to make a logical partition. (Note: logical partitions are not to be confused with logical volumes.)

Extended and logical partitions were created to hack around MS-DOS's limit of 4 partitions per disk, which is why this is so painful.
