[Marcin Wicinski]

cluster is up or down ?

[Meirone Luca]

cluster is up!
when I execute "vgchange -a n vgname" in output I read

[Marcin Wicinski]

you have to halt node2

# cmhaltpkg package1
# cmhaltpkg package2
.
.
# cmhaltnode node2

package1, 2 ... - packages running on node2

and now try to deactivate vg

# vgchange -a n vgname

Hi,

In fact you can desactivate a vg even ifhis part of a cluster.
Did you check if you don't have any hardware problem with the vgapp's disk(s) ?
Try diskinfo, and ioscan on your disks.

I have ever seen like this before.
Have you tried this ?

# fuser /dev/vgapp/*

It will shows you the PIDs that are using /dev/vgapp.
To kill them, use a option "-k" or use kill command.
And try deactivate again.
