[Linux-cluster] What is the proper way to grow LVM/GFS volumes

[Gary Romo]

So what causes clvmd to work this way in the first place?  Why can't it
play nice?

This was great help - I rebooted the nodes one by one, and afterwards
lvextend command worked. I will try to reproduce the errors and see if
killing clvmd does the trick.

   I have also encountered this problem several times, and although this
   list seems to recommend running clvmd -R it has in fact never helped the
   situation (I'm running centos 5.2). The only way I can solve this
   problem is by rebooting all nodes in the cluster and then extending the
   lv.

  We have seen this too, but do not go the route of rebooting.  The nice
  thing about clvmd is that it's not required for the cluster to continue
  running once up and established.  It's purpose is to communicate LVM
  metadata changes to all nodes in the cluster.  So you can simply kill -9
  the clvmd process on all nodes then run service clvmd start. This will
  get clvmd back up and allow pv/vg/lv commmands to complete correctly.
