NAME

       dpm_addpool - define a new disk pool

SYNOPSIS

       #include <sys/types.h>
       #include "dpm_api.h"

       int dpm_addpool (struct dpm_pool *dpm_pool)

DESCRIPTION

       dpm_addpool defines a new disk pool.

       dpm_pool
	      contains the pool definition.

       struct dpm_pool {
	    char      poolname[CA_MAXPOOLNAMELEN+1];
	    u_signed64	   defsize;
	    int       gc_start_thresh;
	    int       gc_stop_thresh;
	    int       def_lifetime;
	    int       defpintime;
	    int       max_lifetime;
	    int       maxpintime;
	    char      fss_policy[CA_MAXPOLICYLEN+1];
	    char      gc_policy[CA_MAXPOLICYLEN+1];
	    char      mig_policy[CA_MAXPOLICYLEN+1];
	    char      rs_policy[CA_MAXPOLICYLEN+1];
	    int       nbgids;
	    gid_t	   *gids;
	    char      ret_policy;
	    char      s_type;
	    u_signed64	   capacity;
	    u_signed64	   free;
	    int       nbelem;
       };

       poolname
	      specifies the disk pool name.

       defsize
	      specifies the default amount of space reserved for a file (in bytes).

       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. Default is 0.

       gc_stop_thresh
	      specifies the percentage of free space in the pool above which the garbage collector is stopped. Default is 0.

       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).

       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).

       nbgids is the size of the array of group ids gids.

       gids   The disk pool is restricted to this set of gids unless the group gid is zero.

       ret_policy
	      specifies the retention policy supported by the disk pool. It can be R (for Replica), O (for Output) or C (for Custodial).

       s_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).

       This function requires ADMIN privilege.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EACCES	    The caller does not have ADMIN privilege.

       EFAULT	    dpm_pool is a NULL pointer.

       EEXIST	    This pool exists already.

       ENOMEM	    Memory could not be allocated for storing the pool definition.

       EINVAL	    The length of poolname exceeds CA_MAXPOOLNAMELEN or the number of gids is too big.

       SENOSHOST    Host unknown.

       SEINTERNAL   Database error.

       SECOMERR     Communication error.
