i have run into a situation where lvm2 does not behave the same as lvm1.
basically i want to be able to create a vg with the same name as an
exported vg.
in lvm1 (v1.0.3) is was able to export the vg and create a vg with the
same name on a different pv. the original "vgturner4" was on /dev/hda6.
# vgchange -a n vgturner4
# vgexport vgturner4
# pvcreate -ff /dev/hda7
# vgcreate vgturner4 /dev/hda7
in lvm2 (v2.00.07) it complained that there was already a vg with that
name. the original vg was on /dev/sdc.
# vgchange -a n vg1
# vgexport vg1
# pvcreate -ff /dev/sda
# vgcreate vg1 /dev/sda
A volume group called 'vg1' already exists.
a "vgscan" in lvm1 returns:
# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "vg0"
vgscan -- found active volume group "vgturner4"
vgscan -- found active volume group "vg0m"
vgscan -- found exported volume group "vgturner4PV_EXP"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
groups
a "vgscan" in lvm2 returns:
# vgscan
Reading all physical volumes. This may take a while...
Found exported volume group "vg1" using metadata type lvm2
i notice that the exported vg in lvm1 is actually renamed but in lvm2 it
retains its original name. any ideas on how to accomplish what i want to
do in lvm2?
