Invalid CRL: The available CRL has expired

Full message

One of the possible GridFTP error messages looks like this:

Diagnosis

Some certificate revocation lists (CRL) in *.r0 files are outdated on the GridFTP server or the client. The CRL files are located in the $X509_CERT_DIR directory or /etc/grid-security/certificates by default.

Solution

Make sure that the following cron entry exists on the server:

/etc/cron.d/fetch-crl

Check /var/log/fetch-crl-cron.log for errors. A non-relocated client installation also should have that cron job. A relocated (tar ball) UI or WN may have a cron job whose name or location cannot be predicted. For example, for the AFS UI at CERN the cron job is run from an "acrontab" owned by the service admin account.
