NAME

   sxvol-create - create volumes on SX clusters

SYNOPSIS

   sxvol    create    [OPTIONS]    -r    N    -s    SIZE    -o    username
   sx://[profile@]cluster/volume

DESCRIPTION

   Create  a  remote  volume  with   specific   settings.   Only   cluster
   administrators can create volumes.

OPTIONS

   -h, --help
          Print help and exit

   --full-help
          Print help, including hidden options, and exit

   -V, --version
          Print version and exit

   -r, --replica=NUMBER
          Set the replica count for the volume. This is a mandatory option
          and specifies how many times the  data  will  be  replicated  on
          different  nodes.  For  example, with replica count 2 the volume
          data will still be  available  when  one  of  the  nodes,  which
          includes  the  volume  data fails (because there's still another
          node with the copy of the data).

   -o, --owner=NAME
          Set the owner of the volume. The owners can modify  volume  ACLs
          (see sxacl(1)) and other settings. This option is mandatory.

   -s, --size=SIZE
          Set  the size of the new volume. The size can be followed by one
          of  the   following   suffixes:   K(-ilobytes),   M(-megabytes),
          G(-igabytes)   and   T(-erabytes)   suffixes.   This  option  is
          mandatory.

   -f, --filter=NAME[="FILTER_OPTIONS"]
          Enable selected filter for the new volume. The  filters  can  do
          some  additional  processing of the data (such as compression or
          encryption), see sxvol-filter(1) for more information.

   --max-revisions=NUMBER
          Set the maximum number of revisions to keep  for  files  in  the
          volume. The revisions are other versions of the file stored when
          the file gets modified. The default value is 1, which means that
          only  a  single version of the file will be stored. See sxrev(1)
          for more information about revisions.

   -D, --debug
          Enable debug messages

   -c, --config-dir=PATH
          Path to the SX configuration directory (default: ~/.sx)

   -c, --filter-dir=PATH
          Path to the SX filter directory (default: /usr/lib/sxclient)

EXAMPLES

   To create a 5GB volume 'data' with replica count  2,  owned  by  'joe',
   which uses the compression filter 'zcomp' run:
       sxvol create -r 2 -o joe -s 5G -f zcomp sx://admin@cluster/data

   To  create  an encrypted volume with replica 3 and default settings for
   'admin' run:
       sxvol create -r 3 -o admin -f aes256 sx://admin@cluster/encrypted
