I'm not planning to run my whole system on btrfs just yet - but I was keen to start running one or two test filesystems on a server that I currently have running Debian squeeze. Everything else on the server has to remain as-is if possible. Thanks for the feedback - I will start looking into the newer kernels and see if I can use one of them with squeeze, or maybe I will just set up a VM for btrfs One thing I've already noticed in 2.6.39 (and both versions of the tools) is that df results are misleading. E.g. if I run regular df (not btrfs fi df), I am seeing the same amount of available space for all filesystems. Is there currently a way to see space used by each subvolume and snapshot and which kernel and tools versions might be needed?
