Hello,
we want to use our Red Hat Enterprise ES 3.0 with lvm as a file server.
The server is connected to a IBM Fast T 900 via qlogic2200 Fiber Channel.
On the FastT I have created a partition with 295 GB.
Fdisk shows this partition as /dev/sda1 with 292,5 GB:
Output of fdisk:
fdisk -l
Platte /dev/sda: 292.5 GByte, 292555849728 Byte
255 Köpfe, 63 Sektoren/Spuren, 35567 Zylinder
Einheiten = Zylinder von 16065 * 512 = 8225280 Bytes
Gerät boot. Anfang Ende Blöcke Id Dateisystemtyp
/dev/sda1 1 35567 285691896 8e Linux LVM
[root at fastlinux lvmgui-0.4]# pvcreate /dev/sda1
pvcreate -- physical volume "/dev/sda1" successfully created
[root at fastlinux lvmgui-0.4]# vgcreate -s 8M vg_daten /dev/sda1
vgcreate -- INFO: maximum logical volume size is 511.98 Gigabyte

I have a volume group with maximum 511.98 Gigabyte and want to create a
logical volume with 292 GB (greater than 266 GB), but lvcreate allow only
34873 extents (= 266 BG).
Where is the resulotion?
Thanks
Andreas
