Description Marc Methot 2018-11-17 22:20:33 UTC

It would be requested to have the option to modify the 'nfs_mount_options' in the [libvirt] section of the nova.conf during the overcloud deployment.

~~~
[libvirt]
# Mount options passed to the NFS client. See section of the nfs man page
# for details.
#
# Mount options controls the way the filesystem is mounted and how the
# NFS client behaves when accessing files on this mount point.
#
# Possible values:
#
# * Any string representing mount options separated by commas.
# * Example string: vers=3,lookupcache=pos
#  (string value)
#nfs_mount_options=<None>
~~~

I could not find this parameter within THT or the openstack-puppet modules.


Cheers,
Marc Methot

Director manages the nfs mount. Example config in environments/storage/nova-nfs.yaml

Comment 2 Ollie Walsh 2018-11-23 11:58:30 UTC

ah, missing some relevant info in the description... this is boot from volume with NFS backed cinder volumes.

Comment 6 Matthew Booth 2018-11-23 16:39:49 UTC

Note that's there's a facility for cinder to pass mount options to nova via 'options' in connection_info. We'd have to ask the cinder folks how that's used in practise.

Comment 7 Matthew Booth 2019-05-23 12:42:05 UTC

This appears to have landed on master.

Verified


(undercloud) [stack@undercloud-0 ~]$ cat virt/extra_templates.yaml 
parameter_defaults:
  ComputeExtraConfig:
    nova::compute::libvirt::nfs_mount_options: "vers=3,lookupcache=pos"




[heat-admin@compute-0 ~]$ sudo crudini --get /var/lib/config-data/puppet-generated/nova_libvirt/etc/nova/nova.conf libvirt nfs_mount_options
vers=3,lookupcache=pos

[heat-admin@compute-1 ~]$ sudo crudini --get /var/lib/config-data/puppet-generated/nova_libvirt/etc/nova/nova.conf libvirt nfs_mount_options
vers=3,lookupcache=pos
