40 command disables one DS when mirroring is enabled.
41 If one mirrored DS is malfunctioning, a system administrator
42 may use this command on the metadata server (MDS) to disable use of this mirror.
43 This command must be used on the MDS and the
45 must be the exact pathname used when mounting the DS on the MDS.
46 Normally this command will fail if there is no valid mirror for the DS
49 The following option is available:
52 This option forces the DS to be disabled even if there is no valid mirror
54 It should only be used to allow the
56 threads to be terminated.
59 If this command fails with
60 .Dq Device not configured
62 means that the DS has already been disabled due to an error either detected
63 by the MDS or reported to the MDS by a client.
65 The pNFS service should continue to run normally so long as the number of
66 operational DSs is at least as many as the level of mirroring.
