dpm_modifyfs: Modify the parameters of a disk pool filesystem

SYNOPSIS

#include <sys/types.h>

#include "dpm_api.h"

int dpm_modifyfs (char *server, char *fs, int status, int weight)

dpm_modifyfs modifies the parameters of a disk pool filesystem.

server: specifies the host name of the disk server where this filesystem is mounted.
fs: specifies the mount point of the dedicated filesystem.
status: Initial status of this filesystem. It can be set to 0 or FS_DISABLED or FS_RDONLY. (-1 will tell the server to not change the current value).
weight: specifies the weight of the filesystem. This is used during the filesystem selection. The value must be positive (-1 will tell the server to not change the current value). It is recommended to use a value lower than 10.

This function requires ADMIN privilege.

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

ENOENT: Filesystem does not exist.
EACCES: The caller does not have ADMIN privilege.
EFAULT: server or fs is a NULL pointer.
EINVAL: The length of server exceeds CA_MAXHOSTNAMELEN or the length of fs exceeds 79.
SENOSHOST: Host unknown.
SEINTERNAL: Database error.
SECOMERR: Communication error.
