Removing stuff from the kernel is a good idea.
What issues have you come across?
I don't remember the release we used in training, but I do remember
getting frustrated as I couldn't figure out why my NFS wouldn't fail
For some reason, when using the GUI to manually failover, it just
borked, but when I did it on the command line it worked.
Then when I re-tried from the luci, it magically worked again. Never
figured out why as we were moving very quickly through labs.
It was for the RHCA storage course.
I have not experienced this on 5.1.
