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

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.

I'm currently in the process of implementing high availability of our
condor queue. I've setup SPOOL to point to a shared space, ad
described in 3.10.1 of the condor manual.
However, this shared space is ONLY writable and readable by the condor
user - this is a current limitation of the way we're creatinig and
sharing a common mount between the machines which will run the shedd.

Currently, things seem to be running ok. I've switched one machine
over to the new configuration and it locks the spool and manages the
queue without problems - other machines will be switched over during

However, i'm seeing the following error messages in my Shedlog. I
assume this has to do with the limitations of our mount. I'm wondering
if this is a serious problem which will bite us later on? As I
mentioned, at the moment, things seem to be running fine.
