Re: CephFS: mount fs - single posing of failure

[LOPEZ Jean-Charles <jelopez@xxxxxxxxxx>]

Hi Oscar,

the mount command accepts multiple MON addresses.

mount -t ceph monhost1,monhost2,monhost3:/ /mnt/foo

If not specified the port by default is 6789.

Hi,

In Ceph, by design there is no single point of failure I  terms of server roles, nevertheless, from the client point of view, it might exist.

In my environment:

Mon1: 192.168.100.101:6789

Mon2: 192.168.100.102:6789

Mon3: 192.168.100.103:6789

Client: 192.168.100.104

I have created a line in /etc/fstab referencing Mon1 but, of course, if Mon1 fails, the mount point gets stuck. 

I'd like to create a vip assigned to any host with tcp port 6789 UP and, in the client, mount the CephFS using that VIP.

Is there any way to achieve this? 

Thanks a lot in advance!
