Hi,

I have a script which does daily back up.

/**********************************

#!/bin/sh
DEVICE="sda1 sda3 sdb1 sdb2 sda5"
if ( ! mt -f /dev/st0 rewind)  then
      echo "No tape in drive" && exit 1
fi

for item in $DEVICE; do
      mount /dev/$item -o remount,ro
      dump -0auqb 64 -f /dev/st0 /dev/$item
      mount /dev/$item -o remount,rw
done

**********************************/

It failed and gave me the following error for one of the file system.

Error message
==========

DUMP: cannot rewrite /etc/dumpdates: Read only file system
DUMP: Entire dump is aborted.
mount: /var is busy.


Can somebody please tell me what cause this error and how should i rectify it. Shall i again run the back and see whether i am getting the error or what. Any help would be highly appreciated.

Thanks in the anticipation that I will get some useful hint to solve the above problem.

Cheers!!

You script is invoking dump with the "u" option, whcih says to update the file /etc/dumpdates,. But you've re-mounted / as readonly so that update will fail.

You can either not mount / as readonly or remove the "u" option from the dump command.

Hi,

Thanks a lot for replying and explaining me about the possible cause of error.
I have made the changes like, removed -u option from the back up script so that it won't write anything now and kept the mouting of the file systems in the read mode only.

I hope tonight it will run properly.

Thanks !
Cheers
