flyride Posted September 28, 2021 Share #1 Posted September 28, 2021 (edited) Redpill devs might want to consider one of the below listed models for support in order to enable this very useful and new feature.

ThorGroup Posted October 8, 2021 Share #2 Posted October 8, 2021 Sadly this "requires at least one btrfs volume that only consists of synology SSDs" - there's probably a reason for that. Quote Link to comment Share on other sites More sharing options...
flyride Posted October 8, 2021 Author Share #3 Posted October 8, 2021 (edited) I'm sure that is to sell those silly overpriced branded SSDs and nothing else. Even if Syno tests for a device model or serial range, this should be defeatable much like the NVMe patch approach. Please consider a platform like this, with full RAIDF1 and decent CPU support.

Rhubarb Posted October 14, 2021 Share #4 Posted October 14, 2021 (edited) No way I'll be upgrading to the specified models - but deduplication of my btrfs volume (8x16TB SHR2) is something I've been looking for for years. Just need to upgrade to 7.0.1 and resolve the dedupe implementation, I guess! Edited October 14, 2021 by Rhubarb Quote Link to comment Share on other sites More sharing options...
Aigor Posted October 19, 2021 Share #5 Posted October 19, 2021 You can compile deduplication program for btrfs https://github.com/markfasheh/duperemove Quote Link to comment Share on other sites More sharing options...

Main priority at present is upgrading my xPenology based platform (Kaby Lake, Xeon E31240v6, 32GB ECC, SAS controller, to DSM7. I'm getting old and not as agile (physically & mentally), to deal with multiple issues concurrently. 2 Quote Link to comment Share on other sites More sharing options...
