[Linux-cluster] Antwort: Re: clvmd does not create vgs

[Michael]

Hi,

vgchange -ay didnt help. Here is the output from pvs on both nodes 

[root at node1 ~]# pvs
  PV                      VG              Fmt  Attr PSize   PFree
  /dev/VolGroup00/storage storage_cluster lvm2 a-     1,14T 1,14T
  /dev/sda2               VolGroup00      lvm2 a-   557,62G    0 
  /dev/sdb1               VolGroup00      lvm2 a-     1,09T    0 

[root at node2 ~]# pvs
  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 

/dev/VolGroup00/storage is my drdb device. I created it on different vg.

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 me
