Question about cluster lock

[R.O.]

Hello,

I have vgexported a VG belonging a cluster; in that VG was the cluster lock. Now, this disk has been used for create another VG. If I re-create the original VG with the original cluster lock disk, and put the cluster mark with "vgchange -c y", and activate it with "vgchange -a e",,will this procedure work??

Regards,

The cluster lock structure is not the same as the cluster identification bits stored in the LVM VGDA when you create a VG and use 'vgchange -c y ' to set the cluster ID and activation mode.

Inb order to initialize the cluster lock structure, contact the support center and request the 'cminitlock' command to re-initiate the lock structure. The command can be used while the cluster is running.

Or you can re-create your cluster by re-running a cmquerycl on your ascii file - it will pick the preferred disk for a cluster lock for you.

Then re-apply the cluster config with a cmapplyconf.

As Geoff had said,

You need to recreate your cluster config. In order to do so, you need to bring down the cluster, modify your cluster config file, then re-compile it.

We have had a few Service Guard TOC's after not having our cluster lock volume group not being set up properly. Really recommend you taking care of it as soon as possible.
