CVMFS Sync Meeting

Thursday 5 Nov 2026, 11:00 → 12:30 Europe/Zurich

31/2-028 (CERN)

Participants: Fabrizio Furano, Georgios Christodoulis, Hugo

 

Bug in the fuse module: Valentin is taking care. Some mods required about the failover through proxies. Mod not generic enough to be incorporated, maybe just a suggestion to that site.
https://github.com/cvmfs/cvmfs/issues/4445
Georgios: this is very site-specific

Fab: how to enforce that e.g. lhcb does not go to the generic proxy? Enforcing is difficult, the client config is just a default.

Low hit ratios is an issue in the proxies and in the S1

Maybe we can improve the way the first dns alias is handled. The client in the case of errors should retry another host in the first alias (which has 3-5 hosts) rather than going to the second alias, which is in general the generic (overloaded) ca-proxy.

Discussed a bit the elastic gateway architecture.
