it works just fine. RHEL Cluster with two common raw devices for the quorum, I didn't bother setting up GFS at the end, since it was not important. I was very disappointed from the RH cluster manager though. all it does it move a list of services without dependency on eachother. it's quite a lot but it's missing some needed features, like defining a logical link or block - service A and B must migrate to new nodes together, but not to one that already runs service C for instance. nope, I can only define to which nodes each service migrates and that's it. For instance, y client wanted a very simple case where three machines run two services. if any of the three machines fails, the other two take over the two services that need to run, but I can't have both services migrating to the same node, and now I cannot prevent this using this tool, I'll have to make funny improvizations in the startup files to get it to "fail" for the cluster manager and force it to migrate it further to another node if this one is busy. this is an ugly kludge, and the only "right" solutiong, per RHEL, is to have 4 rather than 3 machines, each pair takes care of one service and that it. rediculous :-( -- Pop Psychologist Ira Abramov http://ira.abramov.org/email/ ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
