I'm considering running a mailing list program over two (possibly
more) servers by putting its databases on an NFS mounted directory and
mounting it on the secondary (and n-th) servers. The reason for this is
so that I don't have to have copies of the same DB's everywhere, just in
one central location.
However, I was warned that I may run into file locking problems and
that the NFS implementation needed to be really good at locking between
nodes.
I know from experience that the program itself will create locks
every time you tell it to do something, but those locks live for a short
period of time (a few seconds at most, unless it hits an error, in which
case the lock will live for whatever part of that hour before a crontask
nukes it).
Does anyone here have experience in setting programs up to run over
NFS, specifically dealing with file locking?
