Hi, I'm running pretty much the same setup. What you're looking for is located in /etc/modprobe.d/modprobe.conf and /etc/modprobe.d/dist
Do a search for /var/lib/nfs/rpc_pipefs in those files and replace it with /var/lib/rpc_pipefs. Also, I noticed that the RHEL init scripts for nfs and nfslock were somewhat broken in my installed (but it was 5.1 at the time of install so they may have fixed them with 5.2). The nfs init script wouldn't kill nfsd properly and the nfslock init script returned non-LSB compliant values for one or more operations (start, stop, status). --Ryan > Hi, > > I am trying to set up HA-NFS on RHEL5.2.
