Hi,
try running vgmknodes and/or vgchange -a y volgrp0 and try again.
Alternatively try mkfs /dev/mapper/volume1
Cheers,
Pierre

Hi,
Fedora Core release 4 (Stentz)
I am trying to have a play around with LVM and have hit a snag when I came to formatting the LV.
I have a fresh install on a single 18GB disk. The root (/dev/hda1) partition is 6.1G, and there is
about 300MB swap. That leaves about 12GB spare on hda3. I created hda3 and set the partition
type 8e. I created the PV:
--- Physical volume ---
PV Name /dev/hda3
VG Name volgrp0
PV Size 12.48 GB / not usable 0
Allocatable yes
PE Size (KByte) 4096
Total PE 3196
Free PE 1660
Allocated PE 1536
PV UUID ttjcMK-tNnb-59xe-qGtl-7oAn-XGMT-eBvRky
Created a volume group with hda3 in:
--- Volume group ---
VG Name volgrp0
System ID
Format lvm2
Metadata Areas 1
Metadata Sequence No 6
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 1
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size 12.48 GB
PE Size 4.00 MB
Total PE 3196
Alloc PE / Size 1536 / 6.00 GB
Free PE / Size 1660 / 6.48 GB
VG UUID JK7RNE-DHM2-KNtf-Scua-jOs5-5x11-396xaY
and then a 6GB logical volume:
LV Name /dev/volgrp0/volume1
VG Name volgrp0
LV UUID msRAz9-8A4e-dWGO-C9JG-c08Z-R1xG-iYUWoe
LV Write Access read/write
LV Status available
# open 0
LV Size 6.00 GB
Current LE 1536
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:0
However I can not format '/dev/volgrp0/volume1', I get Permission denied.
>mkfs -t ext3 /dev/volgrp0/volume1
Could not stat /dev/volgrp0/volume1 --- Permission denied.
I notice the VG status is resizable, should that be available? When I try and change it, it reports
that it's already available.
Finding all volume groups
Finding volume group "volgrp0"
1 logical volume(s) in volume group "volgrp0" already active
Found volume group "volgrp0"
Activated logical volumes in volume group "volgrp0"
1 logical volume(s) in volume group "volgrp0" now active
Am I missing something?
TIA. Dp.
