oVirt storage balancer
This script takes all configured Storage Domains of oVirt and balances their disks under a defined threshold of occupation. You may exclude certain storage domains, focus it on a concrete data center, adjust the desired threshold and even apply a migration policy (only disks from machines that are up/down at that time, whatever VM's disks...).
This project uses ovirt-engine-sdk-python version 4.x.
Note: This is an unofficial oVirt-related project
Installation
virtualenv venv
. venv/bin/activate
pip install --install-option="--with-nss" pycurl
pip install -r requirements.txt
Note: In case you want to use python3
instead of python2
(which is by the way recommended), you can specify the -p python3
parameter to your virtualenv
command instead:
virtualenv -p python3 venv
Configuration
Copy the config.py.example
file as config.py
and adjust parameters to your needs. An explaination can be found inside the file comments.
Script invocation
# python storage_balancer.py -h
usage: storage_balancer.py [-h] [--one-run] [--daemon] [--show-occupation]
optional arguments:
-h, --help show this help message and exit
--one-run Just executes the balancer once (one step)
--daemon Executes balancer as daemon. By default.
--show-occupation Only shows current storage domain occupation, then
exits..
- If run without parameters, daemon mode will be invoked.
--one-run
and--show-occupation
are incompatible with--daemon
mode, and they have precedence over this latter.
Version
This is version 1.5.
