Hi all,

Though this may appear inappropriate here,it still is related to server (I think). I have a script kicked off by cron every night to make backups to Blu-ray. But for the past couple of days, I see the following error for the dvd+rw-format -b /dev/dvd command:

But when I run the command the next day (from the cron), it works without any problem. It looks like some sort of resource allocation problem (or is it not?) to me. But I tried going through /var/log/messages and dmesg. I am getting no clue out of them.

Has anybody got any idea how to start investigating things?

My platform is CentOS 5.5.

Thanks

Update on this. I tried moving the back up time (the disc writing time in effect) 30 mins later. It works now. But the question remains. Why it failed? How can I investigate why it failed?

Still looking for ideas.

Thanks

Bad news. It failed again with the same message. Still struggling to find what it is.

Any ideas people?

Thanks

Damn me. Here is excerpt from the actual code that does the backup script

I had two workspaces - a development space and a live space. What I usually do is develop the code in the development space, test it, commit to the repository and update the live workspace from the repository.

I have the BK_DATE_FILE variable declared in the ShellUtils.shl. In this case, I had done it only on the development workspace and not in the live one. So the shell script had a blank for BK_DATE_FILE. I now updated the live workspace and it works.

If somebody needs a better explanation, please let me know the exact thing you want to know; I shall try to answer as best as I can.

Thanks for your time.
