Hi all,
i am new on btrfs, i am testing KVM on btrfs (host: kernel x86-64 3.5.3), the performance is reasonable.
I have two question on defrag, can someone help me?
1. According to btrfs wiki, defragment a COW file will produce two unrelated files.
Does it apply to the "autodefrag" mount option?
2. Is there any command for the fragmentation status of a file/dir ? e.g. fragment size, number of fragments.
