SYNOPSIS
#include <sys/types.h>#include "dpm_api.h"
int dpm_addfs (char *poolname, char *server, char *fs, int status, int weight)
DESCRIPTION
dpm_addfs adds a filesystem to a disk pool.- poolname
- specifies the disk pool name previously defined using dpm_addpool.
- 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.
