CernmVM-FS Stratum 0 for non-LHC VOs
Note (4 Nov 2014): This page is now obsolete. Please check [1].
RAL Tier-1 is currently hosting CernVM-FS Stratum-0 repositories for several non-LHC VOs.
The Stratum-0 v2.1 repositories are replicated by the dedicated EGI CernVM-FS Stratum-1 server located at RAL.
Setting up a site to access small VOs CernVM-FS repositories located at RAL
Assuming that your site is already supporting CernVM-FS (client v2.1.X) for LHC VOs, these are the configurations needed to access the na62, mice, hone, wenmr, phys-ibergrid, hyperk, t2k, glast, cernatschool, biomed, snoplus and pheno CernVM-FS areas.
On each worker node create the /etc/cvmfs/domain.d/gridpp.ac.uk.conf file
[root@lcg0999 ~]# cat /etc/cvmfs/domain.d/gridpp.ac.uk.conf CVMFS_PUBLIC_KEY=/etc/cvmfs/keys/gridpp.ac.uk.pub CVMFS_SERVER_URL="http://cvmfs-egi.gridpp.rl.ac.uk:8000/cvmfs/@org@.gridpp.ac.uk;http://cvmfs01.nikhef.nl/cvmfs/@org@.gridpp.ac.uk"
Note 1: If you're using puppet module to configure the CernVM-FS clients, then it is not possible to define 'gridpp.ac.uk' CernVM-FS domain for the time being. Only solution is configuration per VO. The table below shows the current status at UK sites.
| Site | gridpp.ac.uk domain | per VO configuration |
|---|---|---|
| RAL Tier-1 | yes | |
| RALPP | yes | |
| ICL | yes | |
| LIV | ||
| QMUL | yes(?) | |
| OX | yes | |
| GLA | yes | |
| SHEF | yes | |
| MANC | yes | |
| DUR | yes |
In addition, also in /etc/cvmfs/default.local you must specify the names of your local site squids (regardless CernVM-FS client version):
CVMFS_HTTP_PROXY="http://first.squid.domain:3128;http://second.squid.domain:3128"
We use a single pair of masterkeys (private and public) to sign all cvmfs stratum-0 repositories and the public key is needed for authentication at cvmfs client level.
[root@lcg1060 ~]# cat /etc/cvmfs/keys/gridpp.ac.uk.pub -----BEGIN PUBLIC KEY----- MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAp7C4KDvOIEVJepuAHjxE EES1sDdohz0hiU6uvSqxVYjKVR4Y4/0I/D/zLijQI+MHR7859RN0/6fsZ3b3At3l UbvNfqq6DN1zVjjd0xagC6SMBhSfj/iQKQSsG8MXSyiNmM8YalVHJSPqoova6CPE EgLEjnHKTNEogTNjKBwbP2ELPLkfVoNoxxrXPSox7aln8JdgyZzZlBwm98gnFa1v JTVAl0HQnUJ6cjMwO31wIGVMdvZ+P962t+2bPGfOCm6Ly6BusXcLoIIeez5SBerB aHz//NSTZDbHVNPEqpoo1AQVVOo4XJmqo64jBa3G4Dr0zSda1bkZMVhsyUtjhfEB DwIDAQAB -----END PUBLIC KEY-----
A RPM installing the public key and the gridpp.ac.uk.conf file is available and can be provided on request (catalin.condurache@stfc.ac.uk)
The last requirement is that the site local squid(s) are configured to use the stratum-1 server at RAL.
Also do not forget to define the following environment variables:
- for mice users/jobs
VO_MICE_SW_DIR=/cvmfs/mice.gridpp.ac.uk
- for na62 users/jobs
VO_NA62_VO_GRIDPP_AC_UK_SW_DIR=/cvmfs/na62.gridpp.ac.uk
- for hone users/jobs
VO_HONE_SW_DIR=/cvmfs/hone.gridpp.ac.uk

- for phys.vo.ibergrid.eu users/jobs
