[Linux-cluster] CS4 & RHEL4: File System Errors

I'm having some issues with Cluster Suite 4 on RHEL4 u3.
I have a two node cluster with shared storage on a SAN. The service is
running in an Active-Passive environment hence only one node should be
accessing the file system at a time.
I *was* having a problem where a manual failover (clusvcadm -r
<service>) would fail time to time because the unmounting the file
system failed due to being "busy". I then added force_unmount=1 to my
fs tag in cluster.conf to ensure the file system was unmounted. This
seemed to solve the failover failures, however, I began to get journal
errors on my shared storage.
1. Are these errors cropping up because of the forced unmount?
2. How can I ensure that a mount or unmount done by CS is clean?
Thanks in advance.
