Hi All , I need to setup HA clustering using redhat cluster suite on two nodes , primary concern being high availability . Before trying it on production , I am trying to configure the setup on two desktop machines . For storage , I am creating a partition and sharing the partition as a iscsi target on a third machine . Would like to know what are the options for fencing available at the node level . I tried going through the conga interface for creating a shared fence device , I could see one option is using GNBD . virtual machine fencing is there in the list but that is for xen based HA cluster . scsi fencing is there , but as far as what I understand it does not support iscsi target as of now. Manual fencing is also there , and I am planning to use that , but would like to know is there any other options are available for fencing at node level ?
SCSI fencing will work with iscsi if the iscsi target is SPC-3 compliant. The target must also support the preempt-and-abort SCSI subcommand. It really depends on what iscsi target you are using. I've used fence_scsi with iscsi a few times and it has worked, but I know that some iscsi targets have problems.
