Hi, I have a CentOS 4.1 (with a two hdds RAID 1 using mdadm) running
some database system.... I connected a DLT device on its SCSI interface
(/dev/nst0) in order to make some external backup..... I dump several
filesystems (/, /boot /usr /var /home and others)....so and when I try
to dump manualy for expmple /boot I get this:

[root at Server ~]# dump -0vuf /dev/nst0 /boot
  DUMP: Date of this level 0 dump: Thu Sep 13 16:00:02 2007
  DUMP: Dumping /dev/md0 (/boot) to /dev/nst0

  DUMP: Date of this level 0 dump: Thu Sep 13 16:00:02 2007
  DUMP: Date this dump completed:  Thu Sep 13 16:00:06 2007
  DUMP: Average transfer rate: 1427 kB/s
  DUMP: DUMP IS DONE

So, I think I have some problem with dump and some other ACls  (maybe
selinux).... but the fact is that I can't restore nothing because it
seems to be dumping only / filesystem (/dev/md0).. all other filesystems
are not in the tape device....I disabled selinux on this server and
nothing... I always received this error when dumping (ACLs in inode
won't be dumped)

Please, I'm now looking in google but I'd like to hear your opinion
about this error...

Is the DLT devide broken?
Am I making somethig wrong with the command dump?


thanks in advance
Israel
