/etc/lvmtab differences in a MC SG cluster

[Avinash20]

Please execute vgexport first

We need to remove the vg from lvmtab and again add it

[Avinash20]

On Passive node

# vgexport /dev/vg_foo
# mkdir /dev/vg_foo
# mknod /dev/vg_foo/group c 64 0x0X0000
>> "0x0X0000" This is a minor number and should be same as that on the other node
You could find the minor on active node via
ll /dev/vg_foo/group
check for value 0x0X0000 << Here X is a numeric value
# vgimport -s -m /tmp/vgXX.map vgXX
# strings /etc/lvmtab

Hi Mate,

Did you forget to assign points to this post :)

Hi Marco,

Are you still facing some other issue.
If not, please assign the point.

Sorry, I was busy. I need to research this:

root@[foo]/etc> vgimport -s -m /tmp/vg_bar.map vg_bar
Warning: Logical Volume number "7" found on physical volume not found in "/tmp/vg_bar.map".

LVOL7 exists on the active node currently and is valid.

strings /etc/lvmtab is giving me one extra disk for vg_bar which I'll also need to research.

Hi,

Check
# strings /tmp/vg_bar.map

Check if this contains lvol7
Compare /tmp/vg_bar.map on both the nodes
