Hi,
It appeared that CVMFS clients on v2.0.18 couldn't pick the CERN replica with the recommended setting. Therefore a safer solution is to use
CVMFS_SERVER_URL=[log in to unmask]" target="_blank">http://cvmfs-stratum-one.cern.ch:8000/opt/@[log in to unmask]
for non-LHC CVMFS (*.gridpp.ac.uk) repositories, whilst the RAL Stratum-1 is unavailable.
Regards,
Catalin

Subject: CVMFS access for small VOs
Hi,
This is not something meant as a contingency plan for the current problem with the Stratum-1 service at RAL, but it is a good opportunity to announce non-LHC VOs which are making use of CVMFS (mice, na62 and hone) that CERN is mirroring their repositories, therefore could sysadmins at sites supporting these VOs make the following changes please (see also https://www.gridpp.ac.uk/wiki/RALnonLHCCVMFS#CVMFS_Stratum_0_for_non_LHC_VOs)
In /etc/cvmfs/domain.d/gridpp.ac.uk.conf file
CVMFS_SERVER_URL="[log in to unmask];http://cvmfs-stratum-one.cern.ch:8000/opt/@[log in to unmask]" target="_blank">http://cernvmfs.gridpp.rl.ac.uk:8000/opt/@[log in to unmask];http://cvmfs-stratum-one.cern.ch:8000/opt/@[log in to unmask]"
This will ensure that CERN replica will be accessed by the squids if the RAL replica is not available.
This information was meant to be advertised in few days after some further testing at RAL, but I believe this is no more necessary.

Subject: Problem on CVMFS Stratum 1 server at RAL. Update.
Hi,
The problem looks like a hardware problem on the backend storage for our Stratum 1.
We have turned off http on the Stratum 1 machine. This should cause a failover to alternatives - apart from for those small VOs for which there isn't one.
More details to follow.
Gareth
