Hi everyone,
I have a shared storage device that my 2-node cluster can see
(/dev/storage on both nodes). I wanted to set up a GFS system on the
shared storage, but I am having problems getting both nodes to recognise a
clustered volume group. To set up the clustered volume group I have used
one of the cluster nodes (let's call it node 1).
First, I created a physical volume on my storage device
pvcreate /dev/storage
Then I created a clustered volume group
vgcreate -c y storage_vg /dev/storage
However, when I run
vgchange -aly
on the other cluster node (node 2) I get an error stating that node 2
can't find a volume group with the correct UUID. If I run vgscan and then
vgchange -aly the error goes away, but node 2 still can't see storage_vg.
I have also tried using conga without any success.
Can anyone help? Please let me know if you need more info.
Thanks, Mike
