.SH DESCRIPTION
|
||||
\fBreiserfstune\fR is used for tuning the ReiserFS
|
||||
journal. It can change two parameters (journal size and maximum
|
||||
transaction size), and it can move the journal's location to a new specified
|
||||
block device. (The old ReiserFS's journal may be
|
||||
kept unused, or discarded at the user's option.) Note: At the time of
|
||||
writing this feature was implemented for a special release of
|
||||
ReiserFS, and was not expected to be put into the mainstream kernel
|
||||
until approximately Linux 2.5. This means that if you have the stock
|
||||
kernel you must apply a special patch. Without this patch the kernel
|
||||
will refuse to mount the newly modified file system. We will charge
|
||||
$25 to explain this to you if you ask us why it doesn't work.
|
||||
.PP
|
||||
Perhaps the most interesting application of this code is to put the
|
||||
journal on a solid state disk.
|
||||
.TP
|
||||
\fIdevice
|
||||
is the special file corresponding to the newly specified block device (e.g
|
||||
/dev/hdXX for IDE disk partition or /dev/sdXX for the SCSI disk partition).
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
\fB-j\fR | \fB--journal-device\fR \fIFILE
|
||||
\fIFILE\fR is the file name of the block device the file system has
|
||||
the current journal (the one prior to running reiserfstune) on. This option is required when the journal is
|
||||
already on a separate device from the main data device (although it
|
||||
can be avoided with \fB--no-journal-available\fR). If you don't
|
||||
specify journal device by this option, reiserfstune suppose that
|
||||
journal is on main device.
|
||||
.TP
|
||||
\fB--no-journal-available
|
||||
allows \fBreiserfstune\fR to continue when the current journal's block
|
||||
device is no longer available. This might happen if a disk goes bad
|
||||
and you remove it (and run fsck).
|
||||
.TP
|
||||
\fB--journal-new-device \fIFILE
|
||||
\fIFILE\fR is the file name of the block device which will contain the
|
||||
new journal for the file system. If you don't specify this,
|
||||
reiserfstune supposes that journal device remains the same.
|
||||
.TP
|
||||
\fB \-s\fR | \fB\--journal-new-size \fIN
|
||||
\fIN\fR is the size parameter for the new journal. When journal is to
|
||||
be on a separate device - its size defaults to number of blocks that
|
||||
device has. When journal is to be on the same device as the filesytem - its size defaults
|
||||
to amount of blocks allocated for journal by \fImkreiserfs\fR when it
|
||||
created the filesystem. Minimum is 513 for
|
||||
both cases.
|
||||
.TP
|
||||
\fB \-o\fR | \fB\--journal-new-offset \fIN
|
||||
\fIN\fR is an offset in blocks where journal will starts from when journal is to
|
||||
be on a separate device. Default is 0. Has no effect when journal is
|
||||
to be on the same device as the filesystem. Most users have no need
|
||||
to use this feature. It can be used when you want the journals from
|
||||
multiple filesystems to reside on the same device, and you don't want
|
||||
to or cannot partition that device.
|
||||
.TP
|
||||
\fB \-t\fR | \fB\--maximal-transaction-size \fIN
|
||||
\fI\fR is the maximum transaction size parameter for the new
|
||||
journal. The default, and max possible, value is 1024 blocks. It
|
||||
should be less than half the size of the journal. If specifed
|
||||
incorrectly, it will be adjusted.
|
||||
.TP
|
||||
\fB\-f\fR | \fB--force\fR
|
||||
Normally \fBreiserfstune\fR will refuse to change a journal of a
|
||||
file system that was created before this journal relocation code. This
|
||||
is because if you change the journal, you cannot go back (without special
|
||||
option \fB--make-journal-standard\fR) to an old kernel that lacks this feature and be able to use your filesytem. This option forces it to do that. Specified more
|
||||
than once it allows to avoid asking for confirmation.
|
||||
.TP
|
||||
\fB--make-journal-standard\fR
|
||||
As it was mentioned above, if your file system has non-standard journal,
|
||||
it can not be mounted on the kernel without journal relocation
|
||||
code. The thing can be changed, the only condition is that there is reserved
|
||||
area on main device of the standard journal size 8193 blocks (it will be so for
|
||||
instance if you convert standard journal to non-standard). Just
|
||||
specify this option when you relocate journal back, or without relocation
|
||||
if you already have it on main device.
|
||||
.TP
|
||||
\fB-u\fR | \fB--uuid \fIUUID\fR
|
||||
Set the universally unique identifier (\fB UUID \fR) of the filesystem to
|
||||
\fIUUID\fR (see also \fBuuidgen(8)\fR). The format of the UUID is a
|
||||
series of hex digits separated by hypthens, like this:
|
||||

|

\fB-l\fR | \fB--label \fILABEL\fR
|

Set the volume label of the filesystem. \fILABEL\fR can be at most 16
|

characters long; if it is longer than 16 characters, reiserfstune will truncate it.
|
||||
.SH POSSIBLE SCENARIOS OF USING REISERFSTUNE:
|
||||
1. You have ReiserFS on /dev/hda1, and you wish to have
|
||||
it working with its journal on the device /dev/journal
|
||||
.nf
|
||||
.IP
|
||||
boot kernel patched with special "relocatable journal support" patch
|
||||
reiserfstune /dev/hda1 --journal-new-device /dev/journal -f
|
||||
mount /dev/hda1 and use.
|
||||
You would like to change max transaction size to 512 blocks
|
||||
reiserfstune -t 512 /dev/hda1
|
||||
You would like to use your file system on another kernel that doesn't
|
||||
contain relocatable journal support.
|
||||
umount /dev/hda1
|
||||
reiserfstune /dev/hda1 -j /dev/journal --journal-new-device /dev/hda1 --make-journal-standard
|
||||
mount /dev/hda1 and use.
|
||||
.LP
|
||||
2. You would like to have ReiserFS on /dev/hda1 and to be able to
|
||||
switch between different journals including journal located on the
|
||||
device containing the filesystem.
|
||||
.nf
|
||||
.IP
|
||||
boot kernel patched with special "relocatable journal support" patch
|
||||
mkreiserfs /dev/hda1
|
||||
you got solid state disk (perhaps /dev/sda, they typically look like scsi disks)
|
||||
reiserfstune --journal-new-device /dev/sda1 -f /dev/hda1
|
||||
Your scsi device dies, it is three in the morning, you have an extra IDE device
|
||||
lying around
|
||||
reiserfsck --no-journal-available /dev/hda1
|
||||
or
|
||||
reiserfsck --rebuild-tree --no-journal-available /dev/hda1
|
||||
reiserfstune --no-journal-available --journal-new-device /dev/hda1 /dev/hda1
|
||||
using /dev/hda1 under patched kernel
