Hi Renar,
Let's see if it is really the /bin/rm is the problem here. Can you run the
command again without cleanup the temp files as follow:
DEBUG=1 keepTempFiles=1 mmgetstate -a
Thanks,
Tru.

Hallo All,
as a point to the problem, it seems to be that all the delayes are
happening here
DEBUG=1 mmgetstate ?a
??..
/bin/rm
-f /var/mmfs/gen/mmsdrfs.1256 /var/mmfs/tmp/allClusterNodes.mmgetstate.1256 /var/mmfs/tmp/allQuorumNodes.mmgetstate.1256 /var/mmfs/tmp/allNonQuorumNodes.mmgetstate.1256 /var/mmfs/ssl/stage/tmpKeyData.mmgetstate.1256.pub /var/mmfs/ssl/stage/tmpKeyData.mmgetstate.1256.priv /var/mmfs/ssl/stage/tmpKeyData.mmgetstate.1256.cert /var/mmfs/ssl/stage/tmpKeyData.mmgetstate.1256.keystore /var/mmfs/tmp/nodefile.mmgetstate.1256 /var/mmfs/tmp/diskfile.mmgetstate.1256 /var/mmfs/tmp/diskNamesFile.mmgetstate.1256
Any points to this it will be fixed in the near future are welcome.

Betreff: AW: [gpfsug-discuss] Spectrum Scale Cygwin cmd delays
Hallo Roger,
first thanks fort he tip. But we decided to separate the linux-io-Cluster
from the Windows client only cluster, because of security requirements and
ssh management requirements. We can use at this point, local named admins
on Windows and use on Linux a Deamon and an separated Admin-interface
Network for pwless root ssh. Your Hint seems to be CCR related or is this a
Cygwin problem.
@Spectrum Scale Team:
Point1: IP V6 can?t disabled because of applications that want to use this.
But the mmcmi cmd are give us already the right ipv4 adresses.
Point2. There are no DNS-Issues
Point3: We must check these.
Any recommendations to Rogers statements?
Regards Renar

We experienced the same issue and were advised not to use Windows for
quorum nodes. We moved our Windows nodes into the storage cluster which
was entirely Linux and that solved it. If this is not an option, perhaps
adding some Linux nodes to your remote cluster as quorum nodes would help.

Hello Renar,
A few things to try:
1. Make sure IPv6 is disabled. On each Windows node, run "mmcmi host
<hostname>", with <hostname> being itself and each and every node in the
cluster. Make sure mmcmi prints valid IPv4 address.
1. To eliminate DNS issues, try adding IPv4 entries for each cluster
node in "c:\windows\system32\drivers\etc\hosts".
1. If any anti-virus is active, disable realtime scanning on c:\cygwin64
(wherever you installed cygwin 64-bit).
You can also try debugging a script, say: (from GPFS ksh): DEBUG=1
mmlscluster, and see what takes time.

Hello All,
We test spectrum scale on an windows only Client-Cluster (remote mounted to
a linux Cluster) but
the execution of mm commands in cygwin is very slow.
We have tried the following adjustments to increase the execution speed.
* We have installed Cygwin Server as a service (cygserver-config).
Unfortunately, this resulted in no faster execution.
* Adaptation of the hosts file: 127.0.0.1localhost cygdrive wpad
to prevent any DNS problems when accessing ?/cygdrive/...?
* Started them as Administrator
All adjustments have so far not led to any improvement. Are there any hints
to enhance the cmd execution time on windows (w2k12 actual used)
