since a few days we got some problems with our Windows 2008 R2-Nodes in our GPFS-mixed-Cluster.
All nodes are running GPFS 188.8.131.52 and the windows nodes are up 2 date and all in the same Domain. When we try to mount GPFS-Devices / startup GPFS the devices are shown for a bit of a second unter "Computer" and then just an entry with the Drive-Letter and a questionmark is left.
The GPFS-Log contains the f ollowing:
Fri May 31 16:29:36.062 2013: Command: err 0: mount tuifs_video mmremote: Unable to mount /dev/tuifs_video on drive V. The drive letter appears to be in use. Unmounting /dev/tuifs_video ... Fri May 31 16:29:37.034 2013: Command: unmount tuifs_video forced Fri May 31 16:29:37.035 2013: Command: err 0: unmount tuifs_video Fre Mai 31 16:29:38 CEST 2013: finished mounting /dev/tuifs_video
We double and triple-checked our AD-Configuration - it's just a copy of another AD where everything works fine.
Services are running as root@domain and status is "started".
Passwords were changed, we also re-installed one of the systems completely, but still there's nothing.
I hope that anyone of you has a clue, why our system is not working anymore - we don't have.
Thanks for your help,
