Isn't that what http://www.ovirt.org/wiki/Features/AdvancedNfsOptions
all about ?
Y.
Reading that, looks like it's geared toward I/O timeouts, but could
certainly be used for the other options. I wasn't aware of the feature
previously.
My point was simply that we shouldn't be use edit/persist long term for
issues like this. There needs to be either a bug or feature filed so
that we solve it long term.
