Dear Friendly Helpful GridPP-Storage folk, Bristol lcgse01 dmlite-with-hdfs was setup by Dr K using puppet modules. We thought IPv6 was all setup+working on lcgse01 & its HeavyLifter gridftp node io-37-02.acrc.bris.ac.uk (which we call io02). It turns out to our dismay that when from an IPv6 node (eg at CERN, or an IPv6 storage node), lcgse01 is instructed to do a transfer, it hands the request off to IPv4-named io02, not IPv6, see ggus ticket 131613. Thus IPv6 gridftp does not work at Bristol. Dr K is a WiseGuy & might be able to dig thru the puppet stuff (me not v familiar with puppet, or dmlite) but he's unfunded & REAL busy with other. Can anyone out in GRIDPP-STORAGE advise where on the SE lcgse01 might a change be hand-done to make IPv6 gridftp work = in lcgse01 handing off to IPv6-addressed io02? We actually do run puppet fairly frequently on both & wouldn't want our change to be undone.... where in a puppet module on our puppet master we might find the config for gridftp where we need to change it ? If someone's going to ask "what version of dpm puppet module are you using", oi, me not know; might it be /etc/puppetlabs/code/environments/production/modules/dmlite/pkg/lcgdm-dmlite-0.5.5 ???? As for other versions, dpm-1.9.2 dmlite-plugins-hdfs-0.7.8-1.20170221.1131rc globus-gridftp-server-12.4-1 lcgse01 is 6-OS, io02 is 7-OS Note that ggus ticket 131613 says IPv6 xrootd works at Bristol! Again it was in a puppet module - Dr K (nor me!) not know where the config is, but it works (we're glad!). Very grateful for advice!
