This repository contains the source for the OpenStack Manila Data snap.
The manila-data daemon is part of OpenStack Manila (https://docs.openstack.org/manila/latest/), the Shared Filesystems service. It handles data-intensive operations such as:
The snap packages the upstream manila-data binary together with Ceph (ceph-common) and NFS support, manages its configuration files via Jinja2 templating, and runs the service as a strictly-confined snap daemon.
This snap is designed to be used with a deployed OpenStack control plane such as delivered by Sunbeam (https://canonical-openstack.readthedocs-hosted.com/en/latest/how-to/features/shared-filesystem/).
Getting Started
Installation
Install the snap from the Snap Store:
sudo snap install manila-data
Required configuration
The service will not start until the database and message queue connections are provided:
sudo snap set manila-data \
database.url=mysql+pymysql://manila:password@10.152.183.210/manila
sudo snap set manila-data \
rabbitmq.url=rabbit://manila:supersecure@10.152.183.212:5672/openstack
Once both values are set the configure hook will render the configuration files and start (or restart) the manila-data daemon automatically.
Verifying the service
sudo snap services manila-data
Logs are written to syslog. You can also inspect the snap-specific log:
sudo snap logs manila-data
Configuration Reference
All options are set with snap set manila-data <key>=<value> and read with snap get manila-data <key>.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snapd can be installed from Manjaro’s Add/Remove Software application (Pamac), found in the launch menu. From the application, search for snapd, select the result, and click Apply.
Alternatively, snapd can be installed from the command line:
sudo pacman -S snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install manila-data, simply use the following command:
sudo snap install manila-data
Browse and find snaps from the convenience of your desktop using the snap store snap.
