It looks there is something I didn't catch from your messages, among them I think I missed the DRBD thing.
The /dev/VolGroup00/storage are physical devices (pv's) ?
Strange naming as it confuses me to have a VG (VolGroup00) name in it, I tend to read this naming as being a LV (storage being a LV in VG VolGroup00...).
Anyway, if possible to have such names for PV's, are you saying that they are different physical devices on each nodes, the one on node1 being the source device of your DRBD setup and the one on node2 being the destination of your DRBD setup ?
I don't know much DRBD to help you, but were you expecting DRBD to create the VG storage automatically on the destination PV on node2 ?

Hi,
vgchange -ay didnt help. Here is the output from pvs on both nodes
[root@node1 ~]# pvs/dev/VolGroup00/storage storage_cluster lvm2 a- 1,14T 1,14T
PV VG Fmt Attr PSize PFree[root@node2 ~]# pvs
/dev/sda2 VolGroup00 lvm2 a- 557,62G 0
/dev/sdb1 VolGroup00 lvm2 a- 1,09T 0/dev/VolGroup00/storage is my drdb device. I created it on different vg.
PV VG Fmt Attr PSize PFree
/dev/VolGroup00/storage lvm2 -- 1,14T 1,14T
/dev/sda2 VolGroup00 lvm2 a- 557,62G 0
/dev/sdb1 VolGroup00 lvm2 a- 1,09T 0

Betreff: Re: [Linux-cluster] Antwort: Re: clvmd does not create vgs
Hi,On node1, you created the pv /dev/drbd/by-res/repdata (pvcreate) and added it to VG storage_cluster (vgcreate ....).On node2, as long as the device /dev/drbd/by-res/repdata is accessible, a simple vgscan would discover the newly created pv and vg.If there was a locking issue, it would complain on node2 that it couldn't activate any LV from storage_cluster.Can you post the output of pvs on node2 ?This is how it works for meBrem2010/3/8 Bernd Giese <bernd.giese@xxxxxxxxxxxxxxxxxx>

Re: clvmd does not create vgs
have you tried to pvscan/vgscan on node2 after creation on node1 ?
