Yeah well, do make sure you have backups. I've been using btrfs for a couple years now on several systems, and while it mostly works well and is very cool, it has eaten my data a few times. Even recent versions. :) What's funny is that the one box where I did expect trouble, a Wikimedia server used in production with a btrfs file system spanning 48 separate hard drives, worked great under load for 2 years. -- Mark Bergsma <[email protected]> Lead Operations Architect Wikimedia Foundation _______________________________________________ Labs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/labs-l
