# sfcrscinfo -m /dev/sfdsk/gfs/dsk/volume1
/dev/sfdsk/gfs/dsk/volume1:

• MDS/AC

  MDS(P) : The primary MDS on a definition

  MDS(S) : The secondary MDS on a definition

  MDS(I) : The other nodes to which MDS operates

  AC : The node that mount the file system

• STATE/SUB-STATE of MDS

  run - : The primary MDS is running

  wait - : The secondary MDS is waiting for failure recovery of the primary MDS

  imag - : Waiting for failure recovery of the primary MDS or the secondary MDS

  stop - : MDS stopped

  none - : no relation with MDS

  If SUB-STATE is other than "-", MDS is in state-transition.

• STATE/SUB-STATE of AC

  run - : file system is in mounted

  stop - : file system is in unmounted

  If SUB-STATE is other than "-", AC is in state-transition.
