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.
