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. make-bcache(8)
