I am not 100% sure what is the appropriate forum, so I decided to post in Town Square.
I have been told that the Cardiff’s stashcache server is slow, making jobs to stay idle for long period of times.
I don’t have experience with stashcache, so I am not sure how it works. First, is the client supposed to detect slow transfers and automatically switch to another server? Or the server is picked by GeoIP and sticks to that decision?
Would changing the setup in repository /cvmfs/config-egi.egi.eu help with this issue?
Current setup is like this:
[root@lcg2400 ~]# grep -r gravity /cvmfs/config-egi.egi.eu/etc/cvmfs/* /cvmfs/config-egi.egi.eu/etc/cvmfs/config.d/ligo.osgstorage.org.conf:CVMFS_EXTERNAL_URL="$CVMFS_EXTERNAL_URL;https://fiona.uvalight.net:8444//user/ligo/;https://stashcache.gravity.cf.ac.uk:8444//user/ligo/;https://xcache.cr.cnaf.infn.it:8443//user/ligo/;https://xcachevirgo.pic.es:8443//user/ligo/" /cvmfs/config-egi.egi.eu/etc/cvmfs/domain.d/osgstorage.org.conf:CVMFS_EXTERNAL_URL="$CVMFS_EXTERNAL_URL;http://fiona.uvalight.net:8000/;http://stashcache.gravity.cf.ac.uk:8000/;http://xcache.cr.cnaf.infn.it:8000/;http://xcachevirgo.pic.es:8000/"
Would changing the order and moving Cardiff to the end of the list help?
Or this is something that can only be fixed at the site?
Thanks a lot in advance.
