add disk and logical volume to VG owned by a package

[huongbuixuan]

Hi all.
How can I add disk and logical volume to VG owned by package while pacakge is running. I can add it for primary node, but don't know how to add for adoptive node (while package is running)

Thank

Hi
You can add it without any pb.
On primary node:
vgextend/lvextend or lvcreate.
then:
vgexport -p -m mapfile vg
Cp on secondary node the mapfile
and then:
vgexport vg
mkdir /dev/vg
mknod /dev/vg/group c 64 0xXX0000
vgimport -m mapfile vg disk_liste.

The vgimport command don't activate the vg, so there is no risk to activate on both system.
That's all.

Hi,

You just have to vgexport -p your volume on the primary node to get a map file, then vgexport it on the secondary node and reimport it using the mapfile.

Don't forget to adjust also the control files with the new lv if it needs to be mounted and unmounted.

Regards,

Jean-Louis.

This and other LVM tasks related to ServiceGuard packages are discussed in step-by-step thoroughness in technical documents.

There are two documents to walk through the processes you need to perform:

These and over a hundred others are already available in the technical knowledge database to answer the most common questions about ServiceGuard

Hello,

Great documents provided by Stephen.

As an add-on, those and the other MCSG documents can be accessed in the Technical Knowledge Base by using the keywords "uxsg" or "umcsg".

If you know how to add it on the primary node , then all you have to do is export that vg form the primary node into a map file in shareable and priview mode . Then copy the map file onto the adoptive node and vgimport that vg there . Thats all you need to do . And also make sure that on both the nodes your package conf files and package control files are in sync .
