lvcreate error: volume group is active in Shared Mode

[Roy Tamburri]

Hello,

Trying to create new lvol and am getting the following message on a 2 node cluster:

lvcreate: The volume group "/dev/vgsg1" is active in Shared Mode.
Cannot perform configuration change.

Any help would be appreciated.

Thanks,
Roy

Shalom Roy,

vgchange -s n

You may need to shut down packages in order to do this kind of LVM work.

Hi,

The volume group activated in sared mode you can not do any logical volume activities. You need to disale shared mode to perform this.

Best of luck

you have VG activated on more than one node.
you need to go on other nodes, take DB/apps down on other host, do vgchange on VG in question, make it unshared, make is non cluster aware, do vgchange -a n, export from other nodes..

Come on this node, do it unshared, not cluster aware, vgchange -a n, vgchange -a y..
Create lvols.. then again work in reverse.. make it cluster aware, shared on node u working on, export and create map, copy map to other nodes, with help of previous disk files and these map files import VG back,
Hope this helps
Prashant
