if we would like to set a swap file through: dd if=/dev/zero of=/swapfile1 bs=<int number (kb)> count=<bs*int number>
Why do you create a swap file via dd from /dev/zero? Wouldn't be better to create a "hole file" via truncate(2)? Holes don't occupy any space in a file managed by reiser4 cryptcompress plugin.
we should consider bs (block size) equal to cluster size's plugin value? (4k, 8k, 16k, 32k or 64k)
Not necessarily. Clusters are logical blocks in a file which are compressed independently. If file size is not a multiple of cluster size, then file's tail will be compressed unless it is not smaller than cplug->min_size_deflate(). Edward.
