Hi all CernVM-FS has a version for macOS, installation and configuration seem to work, but you will not generate tasks for macOS ? the app is not "portable" ? Other question : on a linux debian Virtual Machine (AWS) I could not do the setup of CernVM-FS, : installation and setup seemed OK (explanations from the CernVM-FS page) but then at the "probe" step of the explanation topic here I only get errors. Thanks. |

For my linux VM issue : in default.local I have this CVMFS_REPOSITORIES=atlas.cern.ch,atlas-condb.cern.ch,grid.cern.ch,cernvm-prod.cern.ch,sft.cern.ch,alice.cern.ch CVMFS_QUOTA_LIMIT=4096 CVMFS_CACHE_BASE=/scratch/cvmfs CVMFS_HTTP_PROXY=DIRECT but then cvmfs_config probe Is it because "you cannot run a VM in a VM" ? |

Is it because "you cannot run a VM in a VM" ? This shouldn't be necessary. Just run a linux VM directly on the host. What could be an issue: - Do you use bridged or NAT network? - Did you set your firewall accordingly? - Did you check the VM's automounter setup? (see: https://cvmfs.readthedocs.io/en/stable/cpt-quickstart.html) |

I don't know much about all this, I use a small "preinstalled" linux VM from a cloud provider (OVH) but I don't really know how to check and/or "configure" any of these... However with your comment I realized that maybe I had missed some steps and I ran again cvmfs_config setup sed -i 's%#+dir:/etc/auto.master.d%+dir:/etc/auto.master.d%' /etc/auto.master systemctl restart autofs and after that the probe was a success, all OK ! So I gave it a try again with another task <core_client_version>7.6.33</core_client_version> I also tried this : cvmfs_config chksetup It did that looping the same errors a number of times and stopped... I also tried this from the doc you mention : mkdir -p /mnt/cvmfs I think all this is way too "raw" for me and my beta testing will end here :) |

Did you configure/restart the automounter service? See Jerome's post and https://cvmfs.readthedocs.io/en/stable/cpt-quickstart.html. In addition: You may unhide your computers on the web preferences page to make debugging easier. |

With a little help from my friends I was able to make it work in my Linux VPS. One of l'AF member wrote a Linux Debian memo (Debian 9 Stretch) and it worked for me, I think some steps were missing in the provided instructions here (and cvmfs website) : 1. CVMFS Installation su (switch to root superuser) (*) wget https://ecsft.cern.ch/dist/cvmfs/cvmfs-release/cvmfs-release-latest_all.deb dpkg -i cvmfs-release-latest_all.deb rm -f cvmfs-release-latest_all.deb apt update apt install cvmfs 2. Various setups (superuser also) wget https://lhcathomedev.cern.ch/lhcathome-dev/download/default.local -O /etc/cvmfs/default.local mkdir -p /etc/auto.master.d/ echo "/cvmfs /etc/auto.cvmfs" > /etc/auto.master.d/cvmfs.autofs systemctl restart autofs cvmfs_config probe echo "kernel.unprivileged_userns_clone = 1" >> /etc/sysctl.conf sysctl -p gpasswd -a boinc cvmfs 3. Restart BOINC client systemctl restart boinc-client I got 12 tasks successfully calculated since yesterday evening. Big thanks to ElGrande (one of) our Linux guru :) Considering all the setup and the difficulty to make this application work, this is frankly not a beta, it is an alpha app !! (*) I was not able to do this, my password would always fail and I know it is the right password, so I prefixed all the above commands with "sudo" and then it worked |
