Hi,
I am using mandrake 10.2 , and have installed
1)device-mapper.1.01.05.tgz
2)LVM2.2.01.15.tgz
and have untar the patches in "/usr/src/linux-2.6.11-6mdk"
I have succesfully created physical volume using : pvcreate
then created volume group using : vgcreate
[root localhost ~]# vgdisplay
--- Volume group ---
VG Name volume1
System ID
Format &n!
bsp;
lvm2
Metadata Areas 2
Metadata Sequence No 1
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 0
Open LV 0
Max PV 0
Cur PV 2
Act
PV 2
VG Size 6.35 GB
PE Size 4.00 MB
Total PE 1626
Alloc PE / Size 0 / 0
Free PE / Size 1626 / 6.35 GB
VG UUID zZO4ie-mfY7-st4p-G6ah-tnyf-S5Nt-7AWkzu
but while creating logical volumes from volume group i get following messages :
[root localhost ~]# lvcreate -L1500 -nshash volume1
/proc/misc: No entry for device-mapper found
Is device-map!
