Hi Tzach, Thank you for getting back! I tested it again with CinderNfsMountOptions: 'rw,sync,nosharecache' in Queens, but still to no avail.
I also noticed that the file /etc/cinder/nfs_shares does not exist on any controller, although in cinder.conf it has "#nfs_shares_config = /etc/cinder/nfs_shares". I am not sure if this is normal for using NFS with the containerized cinder service.
