FLASHFS(4) FLASHFS(4)
NAME
flashfs - journalling file system for flash memory
SYNOPSIS
aux/flashfs [ -Dr ] [ -n nsect ] [ -z sectsize ] [ -f file ]
[ -m mountpoint ]
DESCRIPTION
Flashfs interprets the journal-based file system created by
mkflashfs(8) and stored in file (default /dev/flash/fs) so
that it can be mounted into a Plan 9 file system. Flashfs
is typically used to create a stand alone file system from a
small persistent storage device, such as an erasable flash
memory. It does not authenticate its clients and assumes
each group has a single member with the same name.
The -s option causes flashfs to post its channel on
#s/flashfs. Flashfs mounts itself on mountpoint (default
/n/brzr). The -D option turns on 9P debugging output. The
-r option makes the file system read-only.
The files and directory structure are divided into sectsize
(default 4096) byte blocks. Larger blocks make large files
more compact but take longer to access. Supplying the -n
option forces file to contain exactly nsect sectors.
