    mkfs.btrfs

    
    
    

    SYNOPSIS

           mkfs.btrfs  [ -A alloc-start ] [ -b byte-count ] [  -d data-profile ] [
           -l leafsize ] [  -L label ] [  -m metadata profile ] [  -n nodesize ] [
           -s sectorsize ] [  -h ] [  -V ]  device [  device ... ]
    
    
    

    DESCRIPTION

           mkfs.btrfs  is  used  to  create an btrfs filesystem (usually in a disk
           partition, or an array of disk partitions).  device is the special file
           corresponding  to  the  device  (e.g /dev/sdXX ).  If multiple  devices
           are specified, btrfs is created spanning across the specified  devices.
    
    
    

    OPTIONS

           -A, --alloc-start offset
                  Specify  the  offset  from  the start of the device to start the
                  btrfs filesystem. The default value is zero, or the start of the
                  device.
    
           -b, --byte-count size
                  Specify  the size of the resultant filesystem. If this option is
                  not used, mkfs.btrfs uses all  the  available  storage  for  the
                  filesystem.
    
           -d, --data type
                  Specify  how  the data must be spanned across the devices speci-
                  fied. Valid values are raid0, raid1, raid10 or single.
    
           -l, --leafsize size
                  Specify the leaf size, the least data item in which btrfs stores
                  data. The default value is the page size.
    
           -L, --label name
                  Specify a label for the filesystem.
    
           -m, --metadata profile
                  Specify  how  metadata must be spanned across the devices speci-
                  fied. Valid values are raid0, raid1, raid10 or single.
    
           -n, --nodesize size
                  Specify the nodesize. By default the value is set to  the  page-
                  size.
    
           -s, --sectorsize size
                  Specify the sectorsize, the minimum block allocation.
    
           -V, --version
                  Print the mkfs.btrfs version and exit.
    
    
    

    AVAILABILITY

           mkfs.btrfs  is  part  of  btrfs-progs.  Btrfs  is currently under heavy
           development, and not suitable for any uses other than benchmarking  and
           review.   Please  refer  to the btrfs wiki http://btrfs.wiki.kernel.org
           for further details.
