What should I use to configure a failover cluster under CentOS? Is there Red Hat Cluster Suite or something like that? Thank you in advance. -- Giuseppe Fuggiano

Hi list. I am dealing with DRBD (+GFS as its DLM). GFS configuration needs a CLVMD configuration. So, after syncronized my (two) /dev/drbd0 block devices, I start the clvmd service and try to create a clustered logical volume. I get this: On "alice": [root at alice ~]# pvcreate /dev/drbd0 Physical volume "/dev/drbd0" successfully created [root at alice ~]# vgcreate

How can I do this w/o restarting services or rebooting? Thanks! jlc
