Hi All
I am try to create the Lvm over drbd , which is over LVM
to be more clear
Expected Occurs
lv | /dev/vg2/lv2 | /dev/dm-0/lv2
vg | /dev/vg2 | /dev/dm-0
pvcreate
drbd | /dev/drbd0 | /dev/drbd0
lv | /dev/vg1/lv1 | /dev/vg1/lv1
vg | /dev/vg1 | /dev/vg1
phys. vol | /dev/sda | /dev/sda
here when i tried to create the phisical volume over DRBD
Before pvcreate
# pvs
PV VG Fmt Attr PSize PFree
/dev/sda7 vg1 lvm2 a- 9.02G 8.02G
# pvcreate /dev/drbd0
Physical volume "/dev/drbd0" successfully created
but physical volume drbd0 is not shown in the PVS, but a new pv is there ie
dm-0
# pvs
PV VG Fmt Attr PSize PFree
/dev/dm-0 lvm2 -- 895.81M 895.81M
/dev/sda7 vg1 lvm2 a- 9.02G 8.02G
if try to create a vg on drbd0 its shows error, so i create on dm-0
# vgcreate vg2 /dev/dm-0
Volume group "vg2" successfully created
# lvcreate -n lv2 -L500M /dev/vg2
device-mapper: reload ioctl failed: Invalid argument
Failed to activate new LV.
# lvs
LV VG Attr LSize Origin Snap% Move Log Copy%
lv1 vg1 -wi-ao 1.00G
lv2 vg2 -wi-d- 500.00M
here the lv2 is not able to access, it shows the devic does not exist
so please help me in finding the solution for this problem,
is it possible to create lvm over drbd , which is over lvm
