NAME

       make-bcache - create a cache device

SYNOPSIS

       make-bcache [ -U UUID ] [ -b bucket-size ] device

OPTIONS

       -C     Create a cache

       -B     Create a backing device (kernel functionality not yet implemented)

       -U UUID
              Create a cache device with the specified UUID

       -b bucket-size
              Specifies  the bucket size. Allocation is done in terms of buckets, and cache hits are counted per
              bucket; thus a  smaller  bucket  size  will  give  better  cache  utilization,  but  poorer  write
              performance. The bucket size is intended to be equal to the size of your SSD's erase blocks, which
              seems to be 128k-512k for most SSDs. Must be  a  power  of  two;  accepts  human  readable  units.
              Defaults to 128k.
