PNFSDSKILL(8)           FreeBSD System Manager's Manual          PNFSDSKILL(8)

NAME
     pnfsdskill - disables a pNFS data storage server (DS)

SYNOPSIS
     pnfsdskill [-f] mounted-on-DS-dir

DESCRIPTION
     The pnfsdskill command disables one DS when mirroring is enabled.  If one
     mirrored DS is malfunctioning, a system administrator may use this
     command on the metadata server (MDS) to disable use of this mirror.  This
     command must be used on the MDS and the mounted-on-DS-dir must be the
     exact pathname used when mounting the DS on the MDS.  Normally this
     command will fail if there is no valid mirror for the DS available.

     The following option is available:

     -f      This option forces the DS to be disabled even if there is no
             valid mirror for the DS available.  It should only be used to
             allow the nfsd(8) threads to be terminated.

     If this command fails with "Device not configured" (ENXIO), it probably
     means that the DS has already been disabled due to an error either
     detected by the MDS or reported to the MDS by a client.

     The pNFS service should continue to run normally so long as the number of
     operational DSs is at least as many as the level of mirroring.
