Error description

  • "Disk in use" error when using not partitioned DASD devices.
DASD '/dev/dasdk' is in use. Unmount it first!
mmcrnsd: Unexpected error from
fdasd -a /dev/dasd. Return code: 1
mmcrnsd: [E] Unable to partition DASD
device /dev/disk/by-path/ccw-0.0.0500
mmcrnsd: Failed while processing disk
stanza on node node01.abc.de
%nsd: device=/dev/disk/by-path/ccw-0.0.0500
nsd=scale_data01
servers=node01.abc.de
usage=dataAndMetadata

Local fix

  • Prior running the mmcrnsd command, partition the
DASD devices with fdasd -a, refresh the partition
table on all server nodes, and specify the partitions
of the devices in the mmcrnsd stanza file.
Then run the mmcrnsd command.

Problem summary

  • "Disk in use" error when using not partitioned DASD devices.
DASD '/dev/dasdk' is in use. Unmount it first!
mmcrnsd: Unexpected error from
fdasd -a /dev/dasd. Return code: 1
mmcrnsd: [E] Unable to partition DASD
device /dev/disk/by-path/ccw-0.0.0500
mmcrnsd: Failed while processing disk
stanza on node node01.abc.de
%nsd: device=/dev/disk/by-path/ccw-0.0.0500
nsd=scale_data01
servers=node01.abc.de
usage=dataAndMetadata

Problem conclusion

  • Benefits of the solution:
mmcrnsd runs without the 'Disk in use' problem.

Work around:
Prior running the mmcrnsd command, partition the
DASD devices with fdasd -a, refresh the partition
table on all server nodes, and specify the partitions
of the devices in the mmcrnsd stanza file.
Then run the mmcrnsd command.


Problem trigger:
Running the mmcrnsd command on
not partitioned DASD devices.
