I am trying to setup cluster test environment
mainly for the GFS. The application that will be supported likes to take control
of CPU thread and is not clusterable in terms of process sharing, however it
does talk to SAN where GFS comes in. This is not something we did before so
reading manuals and this email list is our primary source of information. I have
few simple/ or not so simple questions, and would be grateful for any pointers
in the right direction.
Going through documentation, it appears that after
fencing is setup, one would need to allocate resources to support cluster. Is
this only for High Availability Cluster or any cluster, meaning - if I am only
to test GFS do I need to allocate resources in order to launch
I know that GFS service must be launched on a cluster.
Once fencing is configured, what are the steps required to deploy GFS, and any
potential 'bumps' to watch out for?
Some questions regarding fencing:
We are using HP DL385s as the test model. After
researching possible fencing devices we decided to try HP ILO and SCSI fencing
before testing HBA switch fencing. For HP ILO fencing - each of the nodes has HP
ILO name, but I am not sure what goes into hostname - is it the name of the
node, or the IP address of HP ILO?
There isn't a lot of information about SCSI fencing, I
would appreciate any pointers for/against SCSI fencing.
