BTRFS Datastore

5 posts in this topic Last Reply

Recommended Posts

I recently attached a new SSD as a VM datastore, and will be using similar base OS for these. At work we use a SAN that deduplicates the base OS files, and saves us a ton of space. I know BTRFS supports some deduplication and compression, is this something I can do while using it in unRAID? This is an unassigned device, not part of the array or a cache drive.

Compression can be enable, AFAIK btrfs deduplication is disable in the kernel, it's still considered experimental, also from what I understand it currently doesn't work together with compression, you can use one or de other.

How can I enable BTRFS compression?

 

I am new to unRAID and do not see any place to set mount options.

I've got a backup mirror of my Steam game library that seems to be an ideal use case for compression.

 

Curious did anyone try @johnnie.black's suggestion? If so how's it working for you? What's the performance impact?
