NAME

dpm_modifypool - modify a disk pool definition

SYNOPSIS

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

int dpm_modifypool (struct dpm_pool *dpm_pool)

DESCRIPTION

dpm_modifypool modifies a disk pool definition.

dpm_pool: contains the new 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). If set to -1, the current value is unchanged.
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. If set to -1, the current value is unchanged.
gc_stop_thresh: specifies the percentage of free space in the pool above which the garbage collector is stopped. If set to -1, the current value is unchanged.
def_lifetime: specifies the default time a space or volatile file is kept in the system (in seconds). If set to -1, the current value is unchanged.
defpintime: specifies the default time a file is kept on a given disk (in seconds). If set to -1, the current value is unchanged.
max_lifetime: specifies the maximum time a space or volatile file is kept in the system (in seconds). If set to -1, the current value is unchanged.
maxpintime: specifies the maximum time a file is kept on a given disk (in seconds). If set to -1, the current value is unchanged.
nbgids is the size of the array of group ids gids. If set to -1, the: current set is unchanged.
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). If set to 0, the current value is unchanged.
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). If set to 0, the current value is unchanged.
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

ENOENT This pool does not exist.

EACCES The caller does not have ADMIN privilege.

EFAULT dpm_pool is a NULL pointer.

EINVAL The length of poolname exceeds CA_MAXPOOLNAMELEN.

SENOSHOST Host unknown.

SEINTERNAL Database error.

SECOMERR Communication error.
