kcusage - volume groups

Jeff Smee — Thu, 27 Aug 2009 12:29:00 GMT

When I run kcusage on one node on my cluster with not all VGs active.
I get: vgdisplay: Volume group cannot be activated... volume group cannot be displayed.

This normal for kcusage? Why would it need to look at the VGs for kcusage?

Shalom,

In a cluster on the passive node, shared volume groups can not be active, because they are activated on the active node.

I'm aware of that.
But why would kcusage need to activate them?

is this 11.23 or 11.31?

I wonder if it uses it when checking the current usage of the maxvgs kernel parm

Try

kcusage maxvgs

and then another on something thats nothing to do with volume groups like:

kcusage shmseg

Do you get the "vgdisplay" message for both attempts?

Even
kcusage nproc
complains about the non active VGs.

FYI: 11.23

Seems I am at least part right - see here:

The fix seesm to be to install the latest version of KernelConfig product (B.11.23.24) Unfortunately the link takes you only to the version for 11iv3, so youy may need to hunt this product down on an up-to-date core OS DVD

Thanks all.
Looks like the mystery is solved.
Some older version of kcusage had this "bug"

Hi Jeff:

A way of saying "thanks" for the efforts of the folks that responded is to assign points. These act as bread crumbs for future strollers to find solutions to their problems:
