Actualization 2018-02-12 11 AM: AFS is working properly again
An AFS server crash occurred this weekend, also causing unexpected problems in the vicious part of the AFS subsystem. As a result of these failures, some volumes are not available on AFS (and also SW modules are not available) and can not be logged on to some computational nodes and frontends. We're working on the repair.
We apologize for any inconvenience caused.
