<font size=2 face="sans-serif">Hi,</font><br><br><font size=2 face="sans-serif">There is an issue with gpfs.snap which
scans AFM internal mounts. This is issue got fixed in later releases. To
workaround this problem,</font><br><br><tt><font size=2>1. cp /usr/lpp/mmfs/bin/gpfs.snap /usr/lpp/mmfs/bin/gpfs.snap.orig<br> <br>2. Change this line :<br> <br> ccrSnapExcludeListRaw=$($find /var/mmfs \<br> \( -name "proxy-server*" -o -name "keystone*"
