Situation
NSS Pools are taking several minutes to deactivate.
This can cause slow pool migrations when using Novell Cluster Services. (possibly comatose resources)
During the deactivating of the NSS pool you will see several messages in /var/log/messages similar to the following

Resolution
With the August 2011 OES2 patches there is a new NSS parameter"FastWriteOfMessyBeasts". This will write this information
out to disk when it happens and not wait until a sync or pool
deactivation.
Turn this on by doing the following
nsscon
This will show that it is currently OFF
nss /find=FastWriteOfMessyBeasts
/(No)FastWriteOfMessyBeasts Enable/Disable fast update of messy files.
[Value=OFF]
This command turns it on.
nss /FastWriteOfMessyBeasts
Prove that it is ON.
nss /find=FastWriteOfMessyBeasts
/(No)FastWriteOfMessyBeasts Enable/Disable fast update of messy files.
[Value=ON]
exit
Make it persistent across reboots by adding it to the /etc/opt/novell/nss/nssstart.cfg file.
