NAME

       dpm-reservespace - reserve space

SYNOPSIS

       dpm-reservespace  --gspace  size_guaranteed_space  [ --ac_latency access_latency ] [ --gid group_ids ] [ --group group_names ] [ --help ] [
       --lifetime space_lifetime ] [ --poolname pool_name ] [ --ret_policy retention_policy ] [ --s_type space_type ]  [  --si	]  [  --token_desc
       u_token ]

DESCRIPTION

       dpm-reservespace reserves space.

OPTIONS

       size_guaranteed_space
	      desired  size  of  guaranteed  space  in	bytes.	The number may also have a suffix k, M, G, T or P to indicate kB, MB, GB, TB or PB
	      respectively.

       access_latency
	      specifies the access latency requested. It can be O (for ONLINE) or N (for NEARLINE).

       group_ids
	      if not zero, the space is restricted to this comma separated list of group gids.	If the caller does not belong  to  the	group,	it
	      must  have  ADMIN privileges.  By default, the space is reserved for the user if the requester has a proxy without VOMS extension or
	      for the group if the requester has a proxy with VOMS extension.

       group_names
	      if set, the space is restricted to this comma separated list of group names.  If the caller does not belong to the  group,  it  must
	      have ADMIN privileges.

       space_lifetime
	      specifies  the  desired  space  lifetime relative to the current time.  It can be "Inf" (for infinite) or expressed in years (suffix
	      'y'), months (suffix 'm'), days (suffix 'd'), hours (suffix 'h') or seconds (no suffix).

       pool_name
	      if set, the space is reserved in that disk pool.

       retention_policy
	      specifies the retention policy requested. It can be R (for Replica), O (for Output) or C (for Custodial).

       s_type specifies the type of space requested. It can be V (for Volatile), D (for Durable), P (for Permanent) or - (for any).

       u_token
	      specifies the user provided description associated with the request.

       --si   use powers of 1000 not 1024 for sizes.

EXAMPLE

       dpm-reservespace --gspace 10G --lifetime 1d --token_desc myspace

       fe869590-b771-4002-b11a-8e7430d72911

EXIT STATUS

       This program returns 0 if the operation was successful or >0 if the operation failed.

NAME

       dpm-drain - drain a component of the Light Weight Disk Pool Manager

SYNOPSIS

       dpm-drain --poolname pool_name [ --server fs_server ] [ --gid gids ] [ --group groups ] [ --size amount_to_drain ]

       dpm-drain --server fs_server [ --gid gids ] [ --group groups ] [ --size amount_to_drain ]

       dpm-drain --server fs_server --fs fs_name [ --gid gids ] [ --group groups ] [ --size amount_to_drain ]

       dpm-drain --help

DESCRIPTION

       dpm-drain drains a component of the Light Weight Disk Pool Manager: a filesystem, a disk server or a pool, optionally filtered by a list of
       gids/groups. It replicates files which belong to the given list of gids/groups (if specified) to another filesystem and removes the  origi-
       nal file. It gives an error message for files still pinned. The pool name, the disk server name or the filesystem name can be specified.

       Volatile files which have expired will not be copied and will be deleted during the draining process.

       If  no  specfic	file  server and file system is specified, or no limit is placed on the files to drain, then the involved active file sys-
       tem(s) will have their status changed to RDONLY.  If any of the involved file systems are marked as DISABLED they will not have their  sta-
       tus changed, however an attempt will still be made to replicate the files from them and, if successful, delete the original.

       Files which are to be moved and belong to a space will be moved to a different location (e.g. file system or disk server) but remain in the
       same space. If there is no alternate location within the same space an error will be reported for the file and it will not be drained.

       Replicas of files with a lifetime will also have lifetime at least as long as the original. If this is not possible (for example  available
       pools have a maximum lifetime too short) then an error is given and the file will not be drained.

       This command requires ADMIN privilege.

       pool_name
	      specifies the disk pool name previously defined using dpm-addpool.

       server specifies the host name of the disk server to be drained.

       fs     specifies the mount point of the dedicated filesystem.

       gid    specifies the comma separated list of gids to which the files must belong.

       group  specifies the comma separated list of groups to which the files must belong.

       size   specifies the minimum number of bytes to drain. The number may be post-fixed with 'k', 'M', 'G' or 'T' for kilobyte, Megabyte, Giga-
	      byte and Terabyte respectively.  Draining is halted once the desired target has been reached or passed.  If size is not specified or
	      is given as zero dpm-drain will drain all eligible files.

EXAMPLE

	    setenv DPM_HOST dpmhost
	    setenv DPNS_HOST dpnshost

	    dpm-drain --poolname Permanent

	    dpm-drain --server lxb1921.cern.ch

	    dpm-drain --server lxb1921.cern.ch --fs /storage

	    dpm-drain --poolname Permanent --gid 105

	    dpm-drain --server lxb1921.cern.ch --group dteam

	    dpm-drain --server lxb1921.cern.ch --gid 105,104

EXIT STATUS

       This program returns 0 if the operation was successful or >0 if the operation failed.
