### Add readahead feature
volume readahead

option page-size 1MB # unit in bytes
option page-count 2 # cache per file = (page-count x page-size)
subvolumes dht
end-volume
### Add IO-Cache feature
volume iocache
type performance/io-cache
option page-size 256KB
option page-count 2
subvolumes readahead
end-volume
### Add writeback feature
volume writeback
type performance/write-behind
option block-size 1MB
option cache-size 2MB
option flush-behind off
subvolumes iocache
end-volume
The "option flush-behind off" is the reason ?
