Hi, I started using btrfs yesterday and used the version that comes with 2.6.29-rc8. The main reason I wanted to try btrfs is that because I am running on SSD's and the normal wear leveling algorithm of this SSD (MTRON 7535) failed terribly with xfs. (SSD's wore out in 2 months) I have a 64GB ssd mounted with '-o noatime' and '-o ssd'. The load is MySQL with 300-400 inserts/sec 24/7 on a large database with a lot of indexes. Attached is the trace I got this morning. The system ran fine for about 16 hours :) -- Met vriendelijke groet, Tom van Klinken ISP Services BV http://www.isp-services.nl/contact
