 If a user hits one of these two limits he will be blocked from writing on the storage.

-As long as there is free space on $GLOBAL users can apply for more storage space via email to the service email address. The 'Fair use' policy introduced with the commissioning of VSC-3 is still valid, quotas are just to make sure, that no one interferes with the jobs of others. This is why quotas on $GLOBAL are currently not displayed by the Vergabeassistent. +As long as there is free space on ''$GLOBAL'' users can apply for more storage space via email to the service email address.

 The number of chunkfiles displayed can be up to 4 times higher than the actual amount of files stored on the filesystem. This is because big files will be stored distributed on up to 4 storage targets. The number of chunkfiles displayed can be up to 4 times higher than the actual amount of files stored on the filesystem.

 +In order for qutoa enforcement to work it is apparently necessary that user and group IDs are known on the storage servers. Therefore the ''/etc/nslcd.conf'' has to be proper and the service needs to be running.
