NAME

fdmkfs− construct a filesystem on the fast-disk

SYNOPSIS

fdmkfs [ −s nblocks ] [ −f nflist ] part

DESCRIPTION

Fdmkfs constructs an empty Fast-Disk filesystem within the partition part (for example, /dev/rmx0b). 

If present, the −s option instructs fdmkfs to create a filesystem containing nblocks blocks of 4096 bytes each.  In the absence of this option, fdmkfs queries the kernel device driver for the capacity of the partition and sets filesystem size to occupy the entire partition. 

The −f option, if present, instructs fdmkfs to make the freelist be nflist blocks long; if omitted, the freelist will be two blocks long.  A longer freelist permits more fragmentation before compacting is necessary, at the expense of more overhead in managing the longer list.  The default value of two blocks (1022 fragments) is usually adequate.
