The NFS "nosharecache" patch in F7 is broken

2007-08-21 Thread Chuck Ebbert
If people try mounting several exports from the same filesystem, it fails
with confusing error messages if the mount options are different for some
of the mount points. Adding "nosharecache" to the mount options fixes that,
but people with working setups suddenly find they need this new option to
use a setup that used to work without it. Should we just revert that patch?

Adding steved to cc (I don't think he's on the list).

Can't it be made to automatically set the nosharecache flag if it's needed?

Thats been the million dollar question lately... there has been quite a
bit of complaints about this patch... but note the check does do some
correct sanity checking so the changes it point would be a good
thing to do

But with that said, I would if making it a warning first, giving
people time to clean up their setups and then making it an
error later on...

thats is an idea that has been kicked around but it turns out it
becomes very messy very quickly...

Thats been the million dollar question lately... there has been quite a
bit of complaints about this patch... but note the check does do some
correct sanity checking so the changes it point would be a good
