Hi,
For this data challenge, LHCb is trying to use the Tape REST API to recall files from tape at IN2P3.
I'm currently in a situation where all the LHCb staging pool are full with pinned files eve…

Hi,
Lately, we have put the IN2P3 storage (dCache 9.2.6) under a lot of stress, leading to some instabilities. In practice, some `xroot` upload attempts from jobs running on worker nodes ended up h…
