.Dt PNFSDSKILL 8
|
|
.Os
|
|
.Sh NAME
|
|
.Nm pnfsdskill
|
|
.Nd
|
|
disables a pNFS data storage server (DS)
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl f
|
|
.Ar mounted-on-DS-dir
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
.Ar 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.
|
|
.Pp
|
|
The following option is available:
|
|
.Bl -tag -width Ds
|
|
.It Fl 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
|
|
.Xr nfsd 8
|
|
threads to be terminated.
|
|
.El
|
|
.Pp
|
|
If this command fails with
|
|
.Dq 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.
|
|
.Pp
|
|
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.
