This will surely help a good number of new btrfs users who have the good sense to watch this mailing list. Your exposition on the balance command helped to clarify in my mind exactly why someone might want to use the usage= filter with a given figure (it looked like black magic to me before, and its usefulness still wasn't completely clear to me after reading the wiki). You had a lot of practical advice for making and maintaining a new btrfs filesystem. I run a btrfs as my root as well, created under kernel 3.2 and purring right along while I've since moved the kernel to 3.9. I recently updated the userspace tools to 3.12 (from the distro-provided 0.19+something), so I'll be sure to move the kernel up to 3.12 as well before trying anything complex. Thanks for the effort. -Andrew ----- On 2014-Mar-22 03:28, Duncan wrote:> Jon Nelson posted on Fri, 21 Mar 2014 19:00:51 -0500 as excerpted: > -----(snip)----- > Meanwhile, I strongly urge you to read up on the btrfs wiki.
