NAME
dpm-modifypool - modify a disk pool definition SYNOPSIS
dpm-modifypool --poolname pool_name [ --def_filesize defsize ] [ --def_lifetime def_lifetime ] [ --def_pintime defpintime ] [ --gc_start_thresh perc ] [ --gc_stop_thresh perc ] [ --gid pool_gids ] [ --group pool_groups ] [ --help ] [ --max_lifetime max_lifetime ] [ --max_pintime maxpintime ] [ --ret_policy retention_policy ] [ --s_type space_type ] DESCRIPTION
dpm-modifypool modifies a disk pool definition. This command requires ADMIN privilege. OPTIONS
pool_name specifies the disk pool name. It must be at most CA_MAXPOOLNAMELEN characters long. defsize specifies the default amount of space reserved for a file. This is by default in bytes, but the number may also be post-fixed with 'k', 'M' or 'G' for kilobyte, Megabyte and Gigabyte respectively. def_lifetime specifies the default time a space or volatile file is kept in the system (in seconds). defpintime specifies the default time a file is kept on a given disk (in seconds). gc_start_thresh specifies the minimum free space in the pool. If the percentage of free space goes below this value, the garbage collector is started. gc_stop_thresh specifies the percentage of free space in the pool above which the garbage collector is stopped. max_lifetime specifies the maximum time a space or volatile file is kept in the system (in seconds). maxpintime specifies the maximum time a file is kept on a given disk (in seconds). pool_gids The existing list can be reset using a comma separated list of group gids, extended by prefixing the gid by + or reduced by prefix- ing the gid by -. See examples. pool_groups The existing list can be reset using a comma separated list of group names, extended by prefixing the name by + or reduced by pre- fixing the name by -. The keyword "ALL" means non-dedicated pool. See examples. retention_policy specifies the retention policy supported by the disk pool. It can be R (for Replica), O (for Output) or C (for Custodial). space_type indicates the type of space supported in the disk pool. It can be V (for Volatile), D (for Durable), P (for Permanent) or - (to accept any type). EXAMPLE
dpm-modifypool --poolname Volatile --def_filesize 100M --groups -dteam,ops,+atlas EXIT STATUS
This program returns 0 if the operation was successful or >0 if the operation failed. SEE ALSO

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
