Re: [HTCondor-users] Jobs that require root permissions

[Brian Bockelman <bbockelm@xxxxxxxxxxx>]

Hi Michael,

Can you give a few more of the lines around the one you reference?

In particular, I'm curious about which part of the job lifetime this is triggered on.

Hi,

is it possible to use condor to run jobs that require root permissions to run (completely). I have the case where I need a special user to run some adminstrative functionality that requires root permissions on exec hosts. The jobs execute these pieces via sudo. The machines are configured to accept a specific set of sudo command's from that users. In general this works fine. However sometimes such jobs get suspend -- and I don't know why.

In such cases the startlog would say something like this

03/18/13 16:38:08 Directory::setOwnerPriv(): NOT changing priv state to owner of /var/lib/condor/execute/dir_29073/buildbase/29106/proc/2568/task/2580/fdinfo" (0.0), that's root!

which refers to a bind-mount /proc inside a chroot.

Is there a way to make this work reliably?

Thanks,

Michael
