[Gluster-users] [GlusterFS 3.2] Information about hard link

[Julien Groselle]

Thank you !

For the first point, about hard link, great !
I can resume my rebalancing peacefully.

About the mount point in /etc, i will change the "working-directory", and
let's go ;)

For information, my reason was :
* when you are doing a 'rebalance': a mount point will be there during the
time of 'rebalance' (as long as the rebalance is running), and should be on
just the machine issuing the 'rebalance' and should be automatically
unmounted.

Thank you again for the answer time !

Regards,
Julien Groselle.
