Python modules for Ceph iSCSI gateway configuration management
Python package providing the modules used to handle the configuration of an iSCSI gateway, backed by Ceph RBD. The RPM installs configuration management logic (ceph_iscsi_config modules), an rbd-target-gw systemd service, and a CLI-based management tool 'gwcli', replacing the 'targetcli' tool. The configuration management modules may be are consumed by custom Ansible playbooks and the rbd-target-gw daemon. The rbd-target-gw service is responsible for startup and shutdown actions, replacing the 'target' service used in standalone LIO implementations. In addition, rbd-target-gw also provides a REST API utilized by the Ceph dashboard and gwcli tool, and a prometheus exporter for gateway LIO performance statistics, supporting monitoring and visualisation tools like Grafana.

A daemon that handles the userspace side of the LIO TCM-User backstore
A daemon that handles the userspace side of the LIO TCM-User backstore. LIO is the SCSI target in the Linux kernel. It is entirely kernel code, and allows exported SCSI logical units (LUNs) to be backed by regular files or block devices. But, if we want to get fancier with the capabilities of the device we're emulating, the kernel is not necessarily the right place. While there are userspace libraries for compression, encryption, and clustered storage solutions like Ceph or Gluster, these are not accessible from the kernel. The TCMU userspace-passthrough backstore allows a userspace process to handle requests to a LUN. But since the kernel-user interface that TCMU provides must be fast and flexible, it is complex enough that we'd like to avoid each userspace handler having to write boilerplate code. tcmu-runner handles the messy details of the TCMU interface -- UIO, netlink, pthreads, and DBus -- and exports a more friendly C plugin module API. Modules using this API are called "TCMU handlers". Handler authors can write code just to handle the SCSI commands as desired, and can also link with whatever userspace libraries they like.
