DESCRIPTION

16       mkreiserfs  creates  a Linux ReiserFS filesystem on a device (usually a
17       disk partition).
18
19       device is the special file corresponding to a device or to a  partition
20              (e.g /dev/hdXX for an IDE disk partition or /dev/sdXX for a SCSI
21              disk partition).
22
23       filesystem-size
24              is the size in blocks of the filesystem. If omitted,  mkreiserfs
25              will automatically set it.
26

OPTIONS

28       -b | --block-size N
29              N  is  block  size  in bytes. It may only be set to a power of 2
30              within the 512-8192 interval.
31
32       -h | --hash HASH
33              HASH specifies which hash function will sort the  names  in  the
34              directories.  Choose from r5, rupasov, or tea. r5 is the default
35              one.
36
37       --format FORMAT
38              FORMAT specifies the format for the new filsystem. Choose format
39              3.5  or  3.6. If none is specified mkreiserfs will create format
40              3.6 if running kernel is 2.4 or higher, and format 3.5 if kernel
41              2.2  is  running,  and will refuse creation under all other ker‐
42              nels.
43
44       -u | --uuid UUID
45              Sets  the  Universally  Unique  IDentifier  of  the   filesystem
46              to   UUID  (see   also  uuidgen(8)).  The  format  of  the  UUID
47              is  a  series of   hex   digits  separated  by  hypthens,  e.g.:
48              "c1b9d5a2-f162-11cf-9ece-0020afc76f16".    If   the  option   is
49              skipped,  mkreiserfs  will by default generate a new UUID.
50
51       -l | --label LABEL
52              Sets  the  volume  label  of  the filesystem. LABEL can at  most
53              be  16  characters  long;  if  it  is longer than 16 characters,
54              mkreiserfs will truncate it.
55
56       -q | --quiet
57              Sets mkreiserfs to  work  quietly  without  producing  messages,
58              progress  or  questions.  It  is useful, but only for use by end
59              users, if you run mkreiserfs in a script.
60
61       -j | --journal-device FILE
62              FILE is the name of the block device on which is  to  be  places
63              the filesystem journal.
64
65       -o | --journal-offset N
66              N  is  the offset where the journal starts when it is to be on a
67              separate device. Default is 0. N has no effect when the  journal
68              is to be on the host device.
69
70       -s | --journal-size N
71              N  is  the size of the journal in blocks. When the journal is to
72              be on a separate device, its size  defaults  to  the  number  of
73              blocks  that  the device has.  When journal is to be on the host
74              device, its size defaults to 8193 and the maximal possible  size
75              is  32749  (for  blocksize  4k).  The minimum size is 513 blocks
76              (whether the journal is on the host or on a separate device).
77
78       -t | --transaction-max-size N
79              N is the maximum transaction size parameter for the journal. The
80              default,  and  max  possible, value is 1024 blocks. It should be
81              less than half the size of  the  journal.  If  specified  incor‐
82              rectly, it will automatically be adjusted.
83
84       -B | --badblocks file
85              File  is  the  file  name  of the file that contains the list of
86              blocks to be marked as bad on the filesystem. This list  can  be
87              created by /sbin/badblocks -b block-size device.
88
89       -f     Forces  mkreiserfs to continue even when the device is the whole
90              disk, looks mounted, or is not a block device. If -f  is  speci‐
91              fied more than once, it allows the user to avoid asking for con‐
92              firmation.
93
94       -d     Sets mkreiserfs to print debugging  information  during  mkreis‐
95              erfs.
96
97       -V     Prints the version and then exits.
