make-bcache(8)              System Manager's Manual             make-bcache(8)

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 imple-
              mented)

       -U UUID
              Create a cache device with the specified UUID

       -b bucket-size
              Specifies the bucket size. Allocation is done in terms of  buck-
              ets,  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.  De-
              faults to 128k.

                                                                make-bcache(8)
