NAME
mkclicfs - Create Clic File

SYNOPSIS

mkclicfs [-d] [-p pagesize] [-b blocksize] [-c compression] [-l logfile] [-n cores] infile outfile

DESCRIPTION

The infile is a loop image (so far only tested with ext3) that is assumed to use pages of pagesize. The outfile is the Compressed Loop Image Container (Clic), it will contain X parts with blocksize. mkclicfs automatically discards duplicated pages, unless -d is given.

The default for the pagesize is 4096, the default for ext3

The blocksize defines how many pages are grouped together before compression. The default is 32, it is a good balance between overhead and compression ratio.

The compression preset defines on how slow it is or how good it compresses. Compare with xz presets. -c 0 is fast and -c 9 is (very) slow - but the compression rate varies a lot - of course depending on the data. Preset 6 is the default.

The logfile is the logfile that is generated from clicfs -l, clicfs will output the access pattern and mkclicfs will reorder the blocks so they are in order.

The number of cores is by default taken from the system. Sometimes it´s wise to not all of them though.
