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. |
