Thanks for the reply Ryan,
I'll have to look further into how locking is setup on our NetApp FAS 3070.
We were also considering using GFS to handle the locking, have you heard
anything about users having multiple svn compute nodes connecting to a repo
on GFS and using distributed lock manager?
I saw that some people were using svnsync and writethrough proxying. I was
concerned about the read-only copies keeping up during nightly builds when
our developers will often go through thousands of commits. I'll have to look
into the documentation for svnsync a little closer.
