NAMEpnfsdskill —
disables a pNFS data storage server (DS)
SYNOPSIS
DESCRIPTIONThepnfsdskill 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:
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.
