It would require additional concern to keep up, as any time that RedHat/CentOS release an update, then it would have to be updated too.
For our purposes, we did recently build the most recent net-snmp rpms and instructions on how to catch up to whatever current centsos is if the archive is too old. https://hpc.lenovo.com/users/documentation/xcataddingsnmp.html From: Vinícius Ferrão via xCAT-user <xcat-user@lists.sourceforge.net> Sent: Saturday, September 12, 2020 8:11 PM To: xCAT Users Mailing list <xcat-user@lists.sourceforge.net> Cc: Vinícius Ferrão <fer...@versatushpc.com.br> Subject: Re: [xcat-user] [External] Re: Issues with net-snmp on new CentOS 8 system and xCAT 2.16 install Hi Jarrod, so what you’re saying is that net-snmp-perl should now be shipped by the xCAT team instead of relying on the distribution repositories? This would be a permanent solution, right?

So net-snmp-libs cannot be upgraded if net-snmp-perl is installed and you don't also have an upgrade for net-snmp-perl. So it requires an effort to continuously stay on top of net-snmp and build all the rpms so we are at or ahead of the updates. For Lenovo, our approach has been to remove the hard requirement on net-snmp-perl, so that all of xCAT (with the exception of switch based discovery) will work if skipping the net-snmp mess. Of course switch based discovery is popular, for those people the choices are: -Blocking updates to net-snmp*/installing net-snmp without the update repositories enabled -Waiting for xCAT repository to catch up -Building net-snmp* rpms from source to force include the perl support (https://git.centos.org/rpms/net-snmp/tree/c8) -Using confluent for switch based discovery and then feed the macs to xCAT ________________________________ From: Jean-Baptiste Denis <jbde...@pasteur.fr<mailto:jbde...@pasteur.fr>> Sent: Tuesday, September 8, 2020 3:02 AM To: xcat-user@lists.sourceforge.net<mailto:xcat-user@lists.sourceforge.net> <xcat-user@lists.sourceforge.net<mailto:xcat-user@lists.sourceforge.net>> Subject: [External] Re: [xcat-user] Issues with net-snmp on new CentOS 8 system and xCAT 2.16 install > Using the Continous Release repository lead to things like this… Your answer makes me think I was lucky at the time I've installed it, which is not a good situation. I'll try to go back to this problem in the next days. Jean-Baptiste On 9/8/20 1:31 AM, Vinícius Ferrão via xCAT-user wrote: > Thanks Jean, this appears to be a 4 months old bug.
