EXT4SRV(4) EXT4SRV(4)
NAME
ext4srv - ext4 file system
SYNOPSIS
ext4srv [ -Ss ] [ -f file ] [ -g groupfile ] [ -n srvname ]
[ -r (2|3|4) ] [ -b blksize ] [ -I inodesize ] [ -L label ]
DESCRIPTION
Ext4srv is a file server that interprets the Linux Second,
Third and Fourth Extended File Systems. A single instance
of ext4srv can provide access to multiple ext2, ext3 and
ext4 partitions simultaneously.
Ext4srv posts a file descriptor named srvname (default ext4)
in the /srv directory. To access an ext4 file system on a
device, use mount with the spec argument (see bind(1)) the
name of the file holding the raw ext4 file system, typically
the disk or partition. If spec is undefined in the mount,
ext4srv will use file as the default name for the device
holding the file system.
Normally ext4srv creates a pipe to act as the communications
channel between itself and its clients. The -s flag
instructs ext4srv to use its standard input and output
instead. This flag also prevents the creation of an
explicit service file in /srv.
By default, ext4srv will try to parse and use /etc/group
file for permission checks, if available on the mounted
filesystem. The optional -g flag specifies Unix-format
group file that gives the mapping between the numeric user-
and group-ID numbers in the Extended file system and the
strings reported by Plan 9 status inquiries. The file is
assumed to reside on the filesystem where ext4srv executable
is running, not the one to be mounted.
With -S option the filesystem can be mounted in "root" mode,
allowing full access, regardless of permissions.
With -r option the filesystem will be reamed - the old data
erased and the file reformatted as specified. An optional
label can be specified with -L, block size (default is 4096
bytes) with -b and inode size (default is 256 bytes) with
-I.
