# mklogfs(8)

create a LogFS filesystem.

## NAME

**mklogfs** - create a LogFS filesystem.

## SYNOPSIS

**mklogfs** \[*OPTIONS*\] *DEVICE*

## DESCRIPTION

LogFS is a scalable flash filesystem. It is aimed to replace JFFS2 for most uses, but focuses more on large devices. JFFS2 works well enough on small devices, it just gets slow and uses up too much memory on larger ones.

## OPTIONS

- \-c, --compress

  turn compression on.

- \-h, --help

  display help.

- \-s, --segshift

  segment shift in bits.

- \-w, --writeshift

  write shift in bits.

- \--demo-mode

  skip bad block scan; don't erase device.

- \--non-interactive

  turn off safety question before writing.

Segment size and write size are powers of two. To specify them, the appropriate power is specified with the "-s" or "-w" options, instead of the actual size. E.g. "mklogfs -w8" will set a writesize of 256 Bytes (2^8).
