diskover is an open source file system crawler and disk space usage software that uses Elasticsearch to index and manage data across heterogeneous storage systems. Using diskover, you are able to more effectively search and organize files and system administrators are able to manage storage infrastructure, efficiently provision storage, monitor and report on storage use, and effectively make decisions about new infrastructure purchases.

As the amount of file data generated by business' continues to expand, the stress on expensive storage infrastructure, users and system administrators, and IT budgets continues to grow.

Using diskover, users can identify old and unused files and give better insights into data change, file duplication and wasted space. diskover supports crawling local file-systems or over NFS/SMB. Amazon S3 inventory files are also supported.

diskover is written and maintained by Chris Park (shirosai) and runs on Linux and OS X/macOS using Python 2/3.

This is the first tool I've found that can index 7m files/2m directories in under 20 min

$ git clone https://github.com/shirosaidev/diskover.git
$ cd diskover

Download latest version

Install Python dependencies using pip.

$ pip install -r requirements.txt

Copy diskover config diskover.cfg.sample to diskover.cfg and edit for your environment.

Start diskover worker bots (a good number might be cores x 2) with:

$ cd /path/with/diskover
$ python diskover_worker_bot.py

Worker bots can be added during a crawl to help with the queue. To run a worker bot in burst mode (quit after all jobs done), use the -b flag. If the queue is empty these bots will die, so use rq info or rq-dashboard to see if they are running.

To start up multiple bots, run:

$ cd /path/with/diskover
$ sh diskover-bot-launcher.sh

By default, this will start up 8 bots. See -h for cli options including changing the number of bots to start. Bots can be run on the same host as the diskover.py crawler or multiple hosts in the network as long as they have the same nfs/cifs mountpoint as rootdir (-d path) and can connect to ES and Redis (see wiki for more info).

Start diskover main job dispatcher and file tree crawler with (using adaptive batch size and optimize index cli flags):

$ python /path/to/diskover.py -d /rootpath/you/want/to/crawl -i diskover-indexname -a -O

Defaults for crawl with no flags is to index from . (current directory) and files >0 Bytes and 0 days modified time. Empty files and directores are skipped (unless you use -s 0 and -e flags). Max crawl depth is 100 and max depth for dir size calculations is 100 by default. Use -h to see cli options.

Crawl down to maximum tree depth of 3 and only calculate dir size/items to level 3:

$ python diskover.py -i diskover-indexname -a -d /rootpath/to/crawl -M 3 -c 3

Only index files which are >90 days modified time and >1 KB filesize:

$ python diskover.py -i diskover-indexname -a -d /rootpath/to/crawl -m 90 -s 1024

Import Amazon S3 Inventory file(s) (gzipped csv) with:

$ python /path/to/diskover.py -i diskover_s3-indexname --s3 /dir/inventoryfile1.csv.gz

Becoming a Patron gets you access to the OVA files running the latest version of diskover/diskover-web. Fastest way to get up and running diskover. Check out the Patreon page to learn more about how to get access to the OVA downloads.

You can set up diskover and diskover-web in docker, there are a few choices for easily running diskover in docker using pre-built images/compose files.

diskover-web has Dockerfile with instructions for docker-compose.
