Hi Joep,

well, what Patrick meant is, that your system (forget that USB drive in
this moment) already has a VG called VolGroup00 on your internal disk.
The modern FC distros use it as default (i think, i'm using SuSE ;-) ).
Before messing up more using fdisk, just provide us with the output of a
vgdisplay -a ;-) get an impression of the 'disaster' :-).

Btw. the volume group your wanted to create has the name VG0, not
VolGroup00 ;-) ..

Ciao

Klaus & Pattrick,
I'm sorry I asked the wrong question (stupid me!). I interpreted the output of vgcreate wrongly. Yes, Klaus, the VolGroup00 was automatically created by FC when I did an upgrade. The correct question is that VG01 (the name I gave it) occupies 232.88 Gb although I had asked for 250 Gb. Where are the 17.2 GB and can I add


when u buy the disk, vendor count it as 250GB or 250 * 1000 * 1000 *
1000 bytes.

when LVM count it, it is 250 * 1000 * 1000 * 1000 / 1024 / 1024/ 1024 =
232.83GB.

check online, many discussion about this 1024 and 1000 issue.


them to VG01.
When I look with fdisk it says that no information is available for /dev/sda1 and "invalid flag 0x0000 of partition table 4 will be corrected by w(rite)". I assume that all problems have arisen due to the fact that I did a pvcreate on a disk which has a W95 FAT32 partition ( of 250 Gb). I assume the best way is to delete the partition completely and create a new partition (with parted or fdisk?) or are there better methods? Do I have to remove VG01 first?
Please, be lenient to me for these basic questions.
Joep

Ah, Ming,
Thanks! That solves it!.
So I don't have to remove the already created pv. Only fdisk complains because when I do an "fdisk /dev/sda" it sees it still as a FAT32 partition but when I do an "fdisk /dev/sda1" it correctly sees it as a partition which is virtually free but with the invalid flag in partition table 4. As I use it as a backup disk I don't have to boot from it but is a logical volume bootable? One last question: Why can't I use "pvcreate /dev/sda" but have to use "pvcreate /dev/sda1" (as the LV HOW-TO stated the former).
Hope you can help me out with this as well.
Joep
