Re: [Condor-users] Multiple submit hosts

[Mag Gam <magawake@xxxxxxxxx>]

Thanks for the response.

I don't have a shared filesystem. Is it possible to have multiple
instances of quill running? I already have quill running on my central
manager.
Basically, if my Central manager host gets too busy crashes we still
want to be able to view the jobs from other hosts.

I setup a collector on my other host but when I run condor_q i see no
jobs there. However on my primary CM I see the correct results.
