make-bcache(8)make-bcache(8)NAMEmake-bcache - create a cache device
SYNOPSISmake-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
Spcifies 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.
Defaults to 128k.
