6.5. Disabling the Cluster Software
It may become necessary to temporarily disable the cluster software on a cluster member. For example, if a cluster member experiences a hardware failure, you may want to reboot that member, but prevent it from rejoining the cluster to perform maintenance on the system.
Use the
/sbin/chkconfig command to stop the member from joining the cluster at boot-up as follows:
#chkconfig --level 2345 rgmanager off#chkconfig --level 2345 gfs off#chkconfig --level 2345 clvmd off#chkconfig --level 2345 fenced off#chkconfig --level 2345 lock_gulmd off#chkconfig --level 2345 cman off#chkconfig --level 2345 ccsd off
Once the problems with the disabled cluster member have been resolved, use the following commands to allow the member to rejoin the cluster:
#chkconfig --level 2345 rgmanager on#chkconfig --level 2345 gfs on#chkconfig --level 2345 clvmd on#chkconfig --level 2345 fenced on#chkconfig --level 2345 lock_gulmd on#chkconfig --level 2345 cman on#chkconfig --level 2345 ccsd on
You can then reboot the member for the changes to take effect or run the following commands in the order shown to restart cluster software:
service ccsd startservice cman start(orservice lock_gulmd startfor GULM clusters)service fenced start(DLM clusters only)service clvmd start, if CLVM has been used to create clustered volumesservice gfs start, if you are using Red Hat GFSservice rgmanager start, if the cluster is running high-availability services (rgmanager)
