  • 1.  Can I configure two LSF community editions in same network ... ?

    Posted Mon April 24, 2023 10:46 AM



    We are evalutating the Community Edition to introduce LSF.
    Due to the limitations of the Community Edition, I'm going to try configuring 2 LSF cluster.

    One is 1 master and 7 servers.
    The other is 1 master and 4 servers.
    We're going to run them completely separate.

    Is this possible?
    I have an ongoing issue with LSF.

    "User Permission denied?"
    I can't put a job in the LSF after these errors.


    All servers has same log in sbatchd.
    authCmdRequest: ns_getHostNameBySockaddr_(192.168.130.102:38960) failed, errmsg: Name or service not known.

    Exiting LSF results in the following error

    LSF shutdown log

    Q1. Can I run two Community Editions at the same time?
    Q2. Is there a problem with using a DNS server?

    Best Regards

    Q1. Can I run two Community Editions at the same time?
    It should work.  You can't use the same host (or hosts) in two different clusters unless you use a different set of LSF ports for each cluster. 
    Q2. Is there a problem with using a DNS server?
    Yes, DNS will work with LSF.   You do have to setup DNS configuration with both a) host to IP address and b) reserve lookup from IP to host name.  Can you confirm  nslookup works from host name to IP address and reserve lookup (i.e. from IP address to host name)?

    Thanks John Welch.

    Your are right comment.

    I have same result.
    I changed lsf configuration without dns(using hosts files).
    It works find.

    Maybe, I have some problem in DNS configuration.
    I will check it.

    Thanks again for the comment.
