FLASHFS(4)                 Kernel Interfaces Manual                 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  mk‐
       flashfs(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.
