oes11 nss /compscreen

we are migrating our netware nss volumes to a new oes 11 server.
Compression is on both source and destination volumes. 12 hours after
the file migration finished we noticed the used space on the volume
starting increasing very fast and the processors were running high. I
assumed it was decompressing files.
Referring to the "OES 11 SP1: NSS File System Administration Guide for
Linux" I tried to go to nss /compscreen and it said the /compscreen
option was not valid.
So I went to nsscon /compscreen and it said /compscreen was not
supported and I should use NSSMU.
I went to NSSMU and I can't find anything showing compression activities.

Can anyone tell me where the /compscreen info is?
