NAME

       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)

DESCRIPTION

       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 cur-
	      rent 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.

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	    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.
