So we have about 1.3T of logs on toollabs. P628 lists the biggest offender. Almost 1T is just one log file, filled with php warnings and notices. There's a NFS backup going on, so we should clean these up after.
Actually, unlinking a file via NFS should not be any harder on the server than doing it directly - the real thing to watch out for is to make sure it is not currently opened by any process. Something that /can/ be done from the server which might be a better idea is to simply truncate the file.
