Re: [Condor-users] condor q high availability problem

[Steven Timm <timm@xxxxxxxx>]

Hi James--if this works out for you, there are other people who
would be interested to know what type of shared disk space you
were using for the high-availability schedd.  If I remember correctly,
each of the cluster* directories in the schedd spool area is
supposed to be owned by the individual user who is
running the job, at least if you are in a unix uid/gid model where
every condor user is running as an independent uid.
