problem with dd command or maybe AFS problem
Hi, folks.

Sorry for bothering, but maybe someone could help me please.

The problem is the following:
there is some script that copies files from local file system to AFS. The copying is performed with dd command.
The script copies data into some AFS volumes.
The problem appeared with one volume.

Before I thought (and I could see it is so) that if we copy some file into AFS, and quota can be exceeded, dd fails (dd: write error: Disk quota exceeded), but this copied data (any part of it) will not be kept in AFS.
That is if "fs q" showed 80% used before dd, it shows 80% used after failure of dd.

In my case:
before dd we had 95%used, one file (about 40MB) is copied, dd failed, I receive only "afs: failed to store file (over quota)", and "fs q" shows 100% used.
And I see that part of the copied file data is kept on AFS.
The problem is this script is called in other script, and that wrapper script cannot complete in such case.

I'm sorry, maybe I explained it too mazy.

Thanks in advance.

AFS(5)								AFS File Reference							    AFS(5)

NAME

       afs - Introduction to AFS files

DESCRIPTION

       A number of files must reside on the local disk of AFS server and client machines. They belong to the following general categories:

       o   Configuration files define configuration parameters for specific server and kernel processes such as the Backup System Tape Coordinator
	   or the Cache Manager.

       o   Administrative files list information used in administration of server machines, such as a list of privileged users or server
	   encryption keys.

       o   Cache-related files contain cached data or information about cached data, on client machines.

       o   Log files contain tracing messages about the operation of a specific process.

       o   Database files contain database records used to administer the AFS cell.

       o   Controller files control the behavior of a process.

       o   Volume header files represent AFS volumes on server partitions.

       For a description of the format and contents of each file, see its reference page.

       Note for Windows users: Some files described in this document possibly do not exist on machines that run a Windows operating system. Also,
       Windows uses a backslash ("") rather than a forward slash ("/") to separate the elements in a pathname.
