- Fix csum_block_size > 0 unusable with atomic writes in the new store
(almost all atomic write requests generated invalid checksums with csum_block_size > 0)
- Fix monitor sometimes randomly failing to optimize PGs with the "problem is
infeasible or unbounded" message due to not waiting to read full stdout of lp_solve
- Remove reshard_abort optimisation to fix chunked resharding introduced in 3.0.2 possibly
corrupting in-memory OSD state when handling multiple rapid PG count change requests
- Fix removed inodes not disappearing from OSD statistics in the new store, leading to
bloating of the statistics with old inodes
- Increase test coverage for the new store and fix several minor bugs:
- Enabling/disabling of used_for_app was recalculating inode space statistics incorrectly
- Fix object metadata validation on OSD startup rejecting some correct sequences of entries,
possibly leading to OSD being unable to start
- Fix PG activation with EC failing in rare cases with EBUSY when requesting to commit an
already committed write
- Fix a theoretically possible metadata writeback issue on ENOSPC during commit
- Fix monitor failing to optimize PGs in presence of a host with name convertible to
js Number (like 04e278988710) :D
- Fix vitastor-cli dd sometimes (rarely) truncating the image when writing to stdout
- Fix a theoretically possible client connection object leak when io_uring is full
- Fix a leak of RDMA-CM connection objects
- Fix crashes with data_block_size < 32KB (useless setup, but anyway) (#113)

# Dockerized Installation
|
|
|
|
Vitastor may be installed in Docker/Podman. In such setups etcd, monitors and OSD
|
|
all run in containers, but everything else looks as close as possible to a usual
|
|
setup with packages:
|
|
- host network is used
|
|
- auto-start is implemented through udev and systemd
|
|
- logs are written to journald (not docker json log files)
|
|
- command-line wrapper scripts are installed to the host system to call vitastor-disk,
|
|
vitastor-cli and others through the container
|
|
|
|
Such installations may be useful when it's impossible or inconvenient to install
|
|
Vitastor from packages, for example, in exotic Linux distributions.
|
|
|
|
If you don't want just a simple containerized installation, you can also take a look
|
|
at Vitastor Kubernetes operator: https://github.com/Antilles7227/vitastor-operator
|
|
|
|
## Installing Containers
|
|
|
|
The instruction is very simple.
|
|
|
|
1. Download a Docker image of the desired version: \
|
|
`docker pull vitalif/vitastor:v3.0.3`
|
|
2. Install scripts to the host system: \
|
|
`docker run --rm -it -v /etc:/host-etc -v /usr/bin:/host-bin vitalif/vitastor:v3.0.3 install.sh`
|
|
3. Reload udev rules: \
|
|
`udevadm control --reload-rules`
|
|
|
|
And you can return to [Quick Start](../intro/quickstart.en.md).
|
|
|
|
## Upgrading Containers
|
|
|
|
First make sure to check the topic [Upgrading Vitastor](../usage/admin.en.md#upgrading-vitastor)
|
|
to figure out if you need any additional steps.
|
|
|
|
Then, to upgrade a containerized installation, you just need to change the `VITASTOR_VERSION`
|
|
option in `/etc/vitastor/docker.conf` and restart all Vitastor services:
|
|
|
|
`systemctl restart vitastor.target`
|
|
|
|
## QEMU
|
|
|
|
Vitastor Docker image also contains QEMU, qemu-img and qemu-storage-daemon built with Vitastor support.
|
|
|
|
However, running QEMU in Docker is harder to setup and it depends on the used virtualization UI
|
|
(OpenNebula, Proxmox and so on). Some of them also required patched Libvirt.
|
|
|
|
That's why containerized installation of Vitastor doesn't contain a ready-made QEMU setup and it's
|
|
recommended to install QEMU from packages or build it manually.
|
|
|
|
## fio
|
|
|
|
Vitastor Docker image also contains fio and installs a wrapper called `vitastor-fio` to use it from
|
|
the host system.
