NAME

volume.reiser4 - the program for managing reiser4 logical volumes.

SYNOPSIS

volume.reiser4 [ options ] [ FILE ] [ MNT ]

DESCRIPTION

volume.reiser4 is a program to manage reiser4 logical (compound) volumes. It performs operations on logical volumes like adding[removing] a brick to[from] your volume, changing capacity of any brick of your volume, increasing current upper limit on total number of bricks in your volume. On-line options are applicable only to mounted volumes. Other options don’t have such restrictions. This program doesn’t create initial volume. Instead, it operates on bricks, which are formatted partitions. To create a brick use mkfs.reiser4(8) utility. For more details see logical volumes administration guide at Logical Volumes Administration

COMMON OPTIONS

-V, --version

prints program version

-?, -h, --help

prints program help

-y, --yes

assumes an answer ’yes’ to all questions

OFF-LINE OPTIONS

-g, --register DEV

-u, --unregister DEV

unregister a brick associated with device DEV in the system

-l, --list

print list of all bricks registered in the system

ON-LINE OPTIONS

-p, --print N

print information about a brick of serial number N in the volume mounted at MNT

-b, --balance

balance volume mounted at MNT

-z, --resize DEV

change data capacity of a brick associated with device DEV in the volume mounted at MNT. The actual capacity has to be defined by the option "-c (--capacity)"

-c, --capacity VALUE

define new data capacity VALUE for a device specified by option "-z (--resize)"

-a, --add DEV

add a brick associated with device DEV to the volume mounted at MNT

-x, --add-proxy

add a proxy brick associated with device DEV to the volume mounted at MNT

-r, --remove

remove a brick associated with device DEV from the volume mounted at MNT

-q, --scale N

increase 2^N times the upper limit for total number of bricks in the volume mounted at MNT

-m, --migrate

move all data blocks of regular FILE to a brick of serial number N

-i, --set-immobile

set "immobile" property to regular FILE

-e, --clear-immobile

clear "immobile" property of regular FILE

Examples:

To create a volume, choose volume ID and stripe size. Then create a first brick, that will be meta-data brick of your volume:

VOL_ID=`uuidgen`

STRIPE=256K

mkfs.reiser4 -U $VOL_ID -t $STRIPE /dev/sdb1

To add a data brick to your initial volume, bring the former "on-line" (that is, mount e.g. at /mnt). Then format some other block device (e.g. /dev/sdb2) with the same volume ID and stripe size. Finally, using option "-a", add it to the volume:

mount /dev/sdb1 /mnt

mkfs.reiser4 -a -U $VOL_ID -t $STRIPE /dev/sdb2

volume.reiser4 -a /dev/sdb2 /mnt

To remove a brick from logical volume mounted at /mnt simply specify the block device that the brick is associated with, using option "-r":

volume.reiser4 -r /dev/sdb2 /mnt
