I'm wondering if brick shouldn't use those mount options if they are defined ?

[username@hostname cinder]$ cat cinder.conf  | grep mount_options
#backup_mount_options = <None>
backup_mount_options=vers=4.0,rw,sync,nosharecache,context=system_u:object_r:cinder_var_lib_t:s0
#nfs_mount_options = <None>
#nas_mount_options = <None>
#vzstorage_mount_options = <None>
#zfssa_nfs_mount_options =
nfs_mount_options=vers=4.0,rw,sync,nosharecache,context=system_u:object_r:cinder_var_lib_t:s0

os-brick is a library that is used by several services, e.g. nova-compute, that won't have access to cinder.conf.

I think what we need is an RFE that allows cinder to somehow "pass" NFS options to os-brick whenever clients (nova-compute, glance-api, cinder-backup) need to connect to a volume. This is a good topic for the cinder squad to discuss.

Hi,

Are there any plan to implement this feature? Just to have an update after +1y.
