Additionally I noticed that the generated corosync config is not valid, as there is no interface section:

Subject: Re: nfs-ganesha HA with arbiter volume
To: Jiffin Tony Thottan <jthottan@xxxxxxxxxx>

Could you point me to the latest documentation? I've been struggling to find something up-to-date. I believe I have all the prerequisites:

- shared storage volume exists and is mounted

- all nodes in hosts files

- Gluster-NFS disabled

- corosync, pacemaker and nfs-ganesha rpm's installed

Anything I missed?

Everything has been installed by RPM so is in the default locations:

/usr/libexec/ganesha/ganesha-ha.sh

/etc/ganesha/ganesha.conf (empty)

/etc/ganesha/ganesha-ha.conf

Looks fine for me.

After I started the pcsd service manually, nfs-ganesha could be enabled successfully, but there was no virtual IP present on the interfaces and looking at the system log, I noticed corosync failed to start:

As far as what I understand from the logs, it called setup_cluser()[calls `ganesha-ha.sh` script ] but script failed.
Can u please provide following details :
-Location of ganesha.sh file??
-Location of ganesha-ha.conf, ganesha.conf files ?


And also can u cross check whether all the prerequisites before HA setup satisfied ?

Hi Tiemen,

One of the pre-requisites before setting up nfs-ganesha HA is to create and mount shared_storage volume. Use below CLI for that

"gluster volume set all cluster.enable-shared-storage enable"

It shall create the volume and mount in all the nodes (including the arbiter node). Note this volume shall be mounted on all the nodes of the gluster storage pool (though in this case it may not be part of nfs-ganesha cluster).

So instead of manually creating those directory paths, please use above CLI and try re-configuring the setup.

Thanks,
Soumya

    Please send the /etc/ganesha/ganesha-ha.conf file you're using.

    Probably you have included the arbiter in your HA config; that would be
    a mistake.
