Re: [Gluster-devel] Problem with samba/ctdb (clustered samba)

[Amar S. Tumballi]

Hi JR,

 As you said, two glusterfs exports (different process) would solve it. But
yes, its bit complex to maintain.

Meanwhile, if most part of your clients don't use locks, then posix-locks
will act as an dummy layer. It comes into act only when a fnctl()/flock()
calls are made. So, I think you can just use posix-locks translator in the
current glusterfsd process.

Regards,
Amar
