[gpfsug-discuss] 4.2 installer

Have you got a half updated system maybe?

You cant have:
libcap-ng-0.7.3-5.el7.i686 != libcap-ng-0.7.5-4.el7.x86_64

I.e. 0.7.3-5 and 0.7.5-4

I cant check right now, but are ibm shipping libcap-Ng as part of their package?

any help here?
~]# yum -d0 -e0 -y install spectrum-scale-object-4.2.0-0
Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:

         1. You have an upgrade for libcap-ng which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of libcap-ng of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude libcap-ng.otherarch ... this should give you an error
            message showing the root cause of the problem.

         2. You have multiple architectures of libcap-ng installed, but
            yum can only see an upgrade for one of those architectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.

         3. You have duplicate versions of libcap-ng installed already.
            You can use "yum check" to get yum show these errors.

       ...you can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).

       Protected multilib versions: libcap-ng-0.7.3-5.el7.i686 != libcap-ng-0.7.5-4.el7.x86_64

My first suggestion is: Don’t deploy the CES nodes manually – way to many package dependencies. Get those setup right and the installer does a good job.

If you go through and define your cluster nodes to the installer, you can do a GPFS upgrade that way. I’ve run into some issues, especially with clone OS versions of RedHat. (ie, CentOS) It doesn’t give you a whole lot of control over what it does – give it a ty and it may work well for you. But run it in a test cluster first or on a limited set of nodes.

We have multiple clusters with thousands of nsd's surely there is an
upgrade path.  Are you all saying just continue to manually update nsd
servers and manage them as we did previously.  Is the installer not
needed if there are current setups.  Just deploy CES manually?
