Re: [ceph-users] Automated Failover of CephFS Clients

2018-02-20 Thread John Petrini 
I just wanted to add that even if you only provide one monitor IP the
client will learn about the other monitors on mount so failover will still
work. This only presents a problem when you try to remount or reboot a
client while the monitor it's using is unavailable.

Thanks for the hint Linh. I had neglected to read up on mount.fuse.ceph here: 
http://docs.ceph.com/docs/master/man/8/mount.fuse.ceph/<http://docs.ceph.com/docs/master/man/8/mount.fuse.ceph/>

I am trying this right now.

Thanks again.
