[linux-lvm] LVM2 Error

[Adam O'Shay]

Greetings,

I am attempting my first usage of the LVM, on a fresh install of Fedora Core 
2 --> kernel: 2.6.5-1.358.

I have the following rpm installed for LVM: lvm2-2.00.15-2

I have used: pvcreate /dev/hdb and pvcreate /dev/hdc

then I entered: vgcreate vg1 /dev/hdb /dev/hdc ---> output was: "Volume 
group "vg1" successfully
created"

vgdisplay outputs:

module: dm_mod is present...i've been told that is important.

Now here is where the problems start:

root at server :] lvcreate -l 500 vg1 -n samba
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'vg1-samba'.
Failed to activate new LV.


But when i type: lvdisplay I get the following:


--- Logical volume ---
LV Name /dev/vg1/samba
VG Name vg1
LV UUID TTLXfg-dVXq-NmIP-kUKg-sZUw-46fr-nZCCOF
LV Write Access read/write
LV Status available
# open 0
LV Size 1.95 GB
Current LE 500
Segments 1
Allocation next free (default)
Read ahead sectors 0
Block device 253:0


so if the LV is ACTIVE, why do the errors occur??



This one really has me stumped...any help is greatly appreciated!!!!!!
