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.

fs_quota
FS_QUOTA(1) AFS Command Reference FS_QUOTA(1)
NAME
fs_quota - Displays the quota used in the volume containing a directory or file
SYNOPSIS
fs quota [-path <dir/file path>+] [-help]
fs q [-p <dir/file path>+] [-h]
DESCRIPTION
The fs quota command displays the percent of quota consumed in the volume that contains each specified directory or file.
To display more detailed information about the volume and the partition it resides on, use the fs examine and fs listquota commands.
To set volume quota, use the fs setquota or fs setvol command.
CAUTIONS
Currently, the maximum size of a volume is 2 terabytes (2^31 bytes).
OPTIONS
-path <dir/file path>
Names each file or directory for which to display the quota consumed in its parent volume. Partial pathnames are interpreted relative
to the current working directory, which is also the default value if this argument is omitted.
-help
Prints the online help for this command. All other valid options are ignored.
OUTPUT
The output reports the percent of volume quota used, in the following format:
<percent>% of quota used.
EXAMPLES
The following command lists the percent quota used of the volume housing the current working directory:
% fs quota
17% of quota used.
The following command lists the percent quota used of both the volume housing the current working directory's parent directory and the
volume housing the directory /afs/abc.com/usr/smith:
% fs quota -path .. /afs/abc.com/usr/smith
43% of quota used.
92% of quota used.
PRIVILEGE REQUIRED
The issuer must have the "r" (read) permission on the ACL of the root directory of the volume that houses the file or directory named by
the -path argument, and "l" (list) permission on the ACL of each directory that precedes it in the pathname.
