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 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.

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.

       SENOSHOST    Host unknown.

       SEINTERNAL   Database error.

       SECOMERR     Communication error.
