My 3 machines are identical.<br><br>Each machine exports a disk to the cluster via iscsi (it's to simulate a SAN on my test platform).<br>For the moment all is running : dlm + clvm (+ cmirror) + gfs2<br><br>I now want to add the fencing to my cluster (for the moment it's disabled in the cluster config). My problem is to choose the right fencing/stonith.<br><br>My questions :<br><br>- As I have a quorum , do I need fencing ?<br>- I can't use an ipmi/drac or so fencing agent, my cluster is on a very low-cost test platform it hasn't remote reboot/poweroff access.<br>- Maybe I could use the fence_scsi, but how to use it on 3 nodes ? Where should I place the fencing disk ? If the node exporting the disk fails, there is no more fencing.<br>- Any other advice will be helpful :)<br><br>Regards,<br><br>Nicolas.<br> </div></body></html>
