New filesystem, created files are owned by root

[Joshua M. Miller]

Hello!

I have an interesting problem. I am running HP-UX 11.0 and I have just created a new VG with a single LV and a vxfs filesystem on that LV. The funny thing is, whenever the DBA runs a backup script as the sybase user, the backup is created as a file owned by root on this new filesystem.

There are no su or sudo commands in this backup script, it simply runs some isql and compress commands.

Also, I can 'su - sybase' and create files that are properly owned by sybase, so I dont understand what's going on here.

Why would the files be created with root ownership and how can I fix this?

TIA,
Joshua M. Miller

Hi Joshua,

Have you tried running the script with a -x option to aid debugging. YOu maybe able to see where/when this change of ownership is occuring.

Thanks, Berd.

I will try that shortly when the DBA stops all of the processes that I have started through my testing.

I have verified that it's not the filesystem doing the permission change, I redirected the script output to another volume and received the same result as before: the files are owned by root:sys.

[Berd]

Are you able to post the output from when script is run with -x ?

Hi,

check, if the file creating program - or one of its child programs - has owner root and s-Bit set!

I will run with -x shortly and report results. Still waiting on the DBA.

It turns out that the permission issue was caused by the Sybase backup server running as root.

Thank you Berd and Peter for your responses, especially the '-x' tip Berd!
