Date: Sun, 02 Mar 2014 12:00:51 +0100 Message-ID: <2507621.pWqlrcrh1e@fnix> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Sender: linux-btrfs-owner@vger.kernel.org List-ID: Hello, I tried to use "bedup" BTRFS offline deduplication tool on several BTRFS machines, with mixed results : 1/ Crashes with messages stating "programming error", sqlite objects must be used inside of the thread that created them, blah-blah... 2/ Crashes stating that some file/objects miss a "live" attribute (?) 3/ bedup eating all my system RAM, then swap over 7GB until the system trashes itself. Wel, besides that and restarting over and over, I could deduplicate some files and gain some noticeable space, but it looks extremely bugged and unreliable. I tried to email the maintainer with details, twice, thru 2 different channels, got no anwser... And it looks like the GIT has not evolved since August, 2013. So my questions are : - Is "bedup" maintained or abandoned ? - Is it supposed to be usable ? - Should I use it ? - Is there a risk that it causes data loss or corruption ? TIA. Kind regards. -- Swâmi Petaramesh http://petaramesh.org PGP 9076E32E
