Welcome to the Reiser4 Wiki, the Wiki for users and developers of the ReiserFS and Reiser4 filesystems.

For now, most of the documentation is just a snapshot of the old Namesys site (archive.org, 2007-09-29).

There was also a Reiser4 Wiki (archive.org, 2007-07-06) once on pub.namesys.com.

=== DESCRIPTION ===
N is block size in bytes. It may only be set to a power of 2 within the 512-8192 interval.
+
 
-h | --hash HASH
+
<tt>mkreiserfs</tt> creates a ReiserFS filesystem on a device (usually a disk partition).
HASH specifies which hash function will sort the names in the directories. Choose from r5, rupasov, or tea. r5 is the default one.
+
 
--format FORMAT
+
''device'' is the special file corresponding to a device or to a partition (e.g /dev/hdXX for an IDE disk partition or /dev/sdXX for a SCSI disk partition).
FORMAT specifies the format for the new filsystem. Choose format 3.5 or 3.6. If none is specified mkreiserfs will create format 3.6 if running kernel is 2.4 or higher, and format 3.5 if kernel 2.2 is running, and will refuse creation under all other kernels.
+
 
-u | --uuid UUID
+
''filesystem-size'' is the size in blocks of the filesystem. If omitted,  
Sets the Universally Unique IDentifier of the filesystem to UUID (see also uuidgen(8)). The format of the UUID is a series of hex digits separated by hypthens, e.g.: "c1b9d5a2-f162-11cf-9ece-0020afc76f16". If the option is skipped, mkreiserfs will by default generate a new UUID.
+
<tt>mkreiserfs</tt> will automatically set it.
-l | --label LABEL
+
 
Sets the volume label of the filesystem. LABEL can at most be 16 characters long; if it is longer than 16 characters, mkreiserfs will truncate it.
+
=== OPTIONS ===
-q | --quiet
+
 
Sets mkreiserfs to work quietly without producing messages, progress or questions. It is useful, but only for use by end users, if you run mkreiserfs in a script.
+
  -b | --block-size N
-j | --journal-device FILE
+
  N is block size in bytes. It may only be set to a power of 2 within  
FILE is the name of the block device on which is to be places the filesystem journal.
+
  the 512-8192 interval.
-o | --journal-offset N
+
 
N is the offset where the journal starts when it is to be on a separate device. Default is 0. N has no effect when the journal is to be on the host device.
+
  -h | --hash HASH
-s | --journal-size N
+
  HASH specifies which hash function will sort the names in the directories.
N is the size of the journal in blocks. When the journal is to be on a separate device, its size defaults to the number of blocks that the device has. When journal is to be on the host device, its size defaults to 8193 and the maximal possible size is 32749 (for blocksize 4k). The minimum size is 513 blocks (whether the journal is on the host or on a separate device).
+
  Choose from r5, rupasov, or tea. r5 is the default one.
-t | --transaction-max-size N
+
 
N is the maximum transaction size parameter for the journal. The default, and max possible, value is 1024 blocks. It should be less than half the size of the journal. If specified incorrectly, it will automatically be adjusted.
+

[edit] SYNOPSIS

  mkreiserfs [ -dfV ]
             [ -b | --block-size N ]
             [ -h | --hash HASH ]
             [ -u | --uuid UUID ]
             [ -l | --label LABEL ]
             [ --format FORMAT ]

             [ -t | --transaction-max-size N ]
             [ -B | --badblocks file ] device [ filesystem-size ]

[edit] DESCRIPTION

mkreiserfs creates a ReiserFS filesystem on a device (usually a disk partition).

device is the special file corresponding to a device or to a partition (e.g /dev/hdXX for an IDE disk partition or /dev/sdXX for a SCSI disk partition).

filesystem-size is the size in blocks of the filesystem. If omitted, mkreiserfs will automatically set it.

[edit] OPTIONS

 -b | --block-size N
 N is block size in bytes. It may only be set to a power of 2 within 
 the 512-8192 interval.
 -h | --hash HASH
 HASH specifies which hash function will sort the names in the directories.
 Choose from r5, rupasov, or tea. r5 is the default one.
 --format FORMAT
 FORMAT specifies the format for the new filsystem. Choose format 3.5 
 or 3.6. If none is specified mkreiserfs will create format 3.6 if 
 running kernel is 2.4 or higher, and format 3.5 if kernel 2.2
 is running, and will refuse creation under all other kernels.
 -u | --uuid UUID
 Sets the Universally Unique IDentifier of the filesystem to UUID 
 (see also uuidgen(1)).
 The format of the UUID is a series of hex digits separated by hypthens, 
 e.g.: "c1b9d5a2-f162-11cf9ece-0020afc76f16". If the option is skipped, 
 mkreiserfs will by default generate a new UUID.
 -l | --label LABEL
 Sets the volume label of the filesystem. LABEL can at most be 16 
 characters long; if it is longer than 16 characters, mkreiserfs 
 will truncate it.
 -q | --quiet
 Sets mkreiserfs to work quietly without producing messages, progress 
 or questions. It is useful, but only for use by end users, if you 
 run mkreiserfs in a script.
 -j | --journal-device FILE
 FILE is the name of the block device on which is to be places the 
 filesystem journal.
 -o | --journal-offset N
 N is the offset where the journal starts when it is to be on a 
 separate device. Default is 0. N has no effect when the journal 
 is to be on the host device.
 -s | --journal-size N
 N is the size of the journal in blocks. When the journal is to be 
 on a separate device, its size defaults to the number of blocks that
 the device has. When journal is to be on the host device, its size 
 defaults to 8193 and the maximal possible size is 32749 (for blocksize
 4k). The minimum size is 513 blocks (whether the journal is on the
 host or on a separate device).
 -t | --transaction-max-size N
 N is the maximum transaction size parameter for the journal. The
 default, and max possible, value is 1024 blocks. It should be less 
 than half the size of the journal. If specified incorrectly, it will
 automatically be adjusted.
 -B | --badblocks file
 File is the file name of the file that contains the list of blocks to 
 be marked as bad on the filesystem. This list can be created by 
 badblocks -b block-size device.
 -f Forces mkreiserfs to continue even when the device is 
 the whole disk, looks mounted, or is not a block device. If -f 
 is specified more than once, it allows the user to avoid asking 
 for confirmation.
 -d Sets mkreiserfs to print debugging information during mkreiserfs.
 -V Prints the version and then exits.
