My Gitea Backup & Restore Scripts
#!/bin/bash
# `gitea dump` doesn't currently back up LFS data as well, only git repos
# It primarily backs up the SQL DB, and also the config / logs
# We'll backup like this:
# * "gitea dump" to backup the DB and config etc
# * tar / bzip all the repos since they will be skipped
# * Not rotated because git data is immutable (normally) so has all data
# * rsync LFS data directly from /volume/docker/gitea/git/lfs
# * No need for rotation since all files are immutable

Consumer-grade GPU passthrough in an OpenStack system (NVIDIA GPUs)

Consumer-grade GPUs in an OpenStack system (NVIDIA GPUs)

Assumptions

This assumes you have GTX980 cards in your system (PCI id 10de:13c0 & 10de:0fbb per card). Just add more IDs for other cards in order to make this more generic. This also assumes nova uses qemu-kvm as the virtualization hypervisor (qemu-system-x86_64). This seems to be the default on OpenStack Newton when installed using openstack-ansible.

We assume OpenStack Newton is pre-installed and that we are working on a Nova compute node. This has been tested on an Ubuntu 16.04 system where I installed OpenStack AIO version 14.0.0 (different from the git tag used in the instructions!): http://docs.openstack.org/developer/openstack-ansible/developer-docs/quickstart-aio.html

Prepare the system for GPU passthrough (set up IOMMU/vfio/...)

Note: This is heavily based on information from https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Enabling_IOMMU adapted for Ubuntu 16.04
