Re: Automated Failover of CephFS Clients

[Paul Kunicki <pkunicki@xxxxxxxxxxxxxx>]

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/

I am trying this right now. 

Thanks again.

Why are you mounting with a single monitor? What is your mount command or /etc/fstab? Ceph-fuse should use the available mons you have on the client's /etc/ceph/ceph.conf. 

e.g our /etc/fstab entry:

none    /home   fuse.ceph       _netdev,ceph.id=myclusterid,ceph.client_mountpoint=/home,nonempty,defaults  0       0

Subject: Automated Failover of CephFS Clients

 

We currently have multiple CephFS fuse clients mounting the same filesystem from a single monitor even though our cluster has several monitors. I would like to automate the fail over from one monitor to another. Is this possible and where should I bee looking for guidance on accomplishing this in production? I would like to avoid involving NFS if possible and Pacemaker seems to be overkill but we can go that route if that is what is in fact needed?

We are currently at 12.2.2 on Centos 7.4.

Thanks.
