[linux-lvm] half my space lost



Hi,

I'm using LVM 1.0.7 on Linux 2.4.22 (Mandrake 9.2).
I'm triyng to setup a VG build on RAID 1 partitions.
When the parition is added to the VG, half of it space mysteriously disapear.

for example:

my RAID 1 partitions are /dev/md/7 and /dev/md/8 and are about 128Mb size.

[root fw root]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/md/7"                               is in no VG
[125.38 MB]
pvscan -- inactive PV "/dev/md/8"                               is in no VG
[125.38 MB]
pvscan -- ACTIVE   PV "/dev/ide/host0/bus1/target0/lun0/part13" of VG "lvm1" [17
GB / 16.97 GB free]
pvscan -- total: 3 [17.28 GB] / in use: 1 [17.04 GB] / in no VG: 2 [250.75 MB]

I create one VG using one of the RAID 1 partitions:

[root fw root]# vgcreate secured /dev/md/7
vgcreate -- INFO: using default physical extent size 32 MB
vgcreate -- INFO: maximum logical volume size is 2 Terabyte
vgcreate -- doing automatic backup of volume group "secured"
vgcreate -- volume group "secured" successfully created and activated

The size of the partition get shrink by half:

[root fw root]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/md/7"                               of VG "secured"
[64 MB / 64 MB free]
pvscan -- inactive PV "/dev/md/8"                               is in no VG
[125.38 MB]
pvscan -- ACTIVE   PV "/dev/ide/host0/bus1/target0/lun0/part13" of VG "lvm1"
[17 GB / 16.97 GB fr
pvscan -- total: 3 [17.28 GB] / in use: 2 [17.16 GB] / in no VG: 1 [125.38 MB]

Is this a known/solved problem?
Did I made a mistake?

Thanks in advance for your help.
Regards.
