Hi all, This serie of patches adds a new command called "btrfs filesystem disk-usage". I added this command because it is not so easy to get the information about the disk usage from the command "fi df" and "fi show".
>From the man page (see 2nd patch): [...] The command btrfs filesystem disk-usage is used to query the status of the chunks, how many space on the disk(s) are used by the chunks, how many space are available in the chunks, and an estimation of the free space of the filesystem. [...] $ ./btrfs filesystem disk-usage --help usage: btrfs filesystem disk-usage [-d][-s][-k] <path> [<path>..] Show space usage information for a mount point(s). -k Set KB (1024 bytes) as unit -s Don't show the summary section -d Don't show the detail section $ ./btrfs filesystem disk-usage / Path: / Summary: Disk_size: 72.57GB Disk_allocated: 25.10GB Disk_unallocated: 47.48GB Logical_size: 23.06GB Used: 11.01GB Free_(Estimated): 55.66GB (Max: 59.52GB, Min: 35.78GB) Data_to_disk_ratio: 92 % Details: Chunk-type Mode Chunk-size Logical-size Used Data Single 21.01GB 21.01GB 10.34GB System DUP 80.00MB 40.00MB 4.00KB System Single 4.00MB 4.00MB 0.00 Metadata DUP 4.00GB 2.00GB 686.93MB Metadata Single 8.00MB 8.00MB 0.00 Where: Disk_size -> sum of sizes of teh disks Disk_allocated -> sum of chunk sizes Disk_unallocated -> Disk_size - Disk_allocated Logical_size -> sum of logical area sizes Used -> logical area used Free_(Estimated) -> on the basis of allocated chunk, an estrapolation of the free space Data_to_disk_ratio -> ration between the space occuped by a chunk and the real space available ( due to duplication and/or RAID level) Chunk-type -> kind of chunk Mode -> allocation policy of a chunk Chunk-size -> area of disk(s) occuped by the chunk (see it as raw space used) Logical-size -> logical area size of the chunk Used -> portion of the logical area used by the filesystem You can pull this change from http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git branch disk_free Comments are welcome.
