We are planning to serve web pages in a failsafe manner using
geographically separated web servers, distributed director,
and AFS.
This is going to require that we run a "vos release" on a periodic,
automated basis.
* if the read/write version of a volume has not changed since
the last release, will "vos release" no-op, or will it try to
synchronize anyway.
* would it make sense to attempt to determine whether a volume
has changed before doing a release? --I don't have a very good
sense for how resource expensive "vos release" is.
if it would be a good idea to only release when necessary, is there
a more efficient way to discover whether a read/write volume has
changed since the last release other than comparing the mtimes
of all directories in the volumes?
Is anyone else doing this sort of thing?
