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 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  utiliza-
              tion,  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.

                                                                                   make-bcache(8)
