Description of problem: On Red Hat Enterprise Linux Server release 6.5 (Santiago), I can not start nfs process when /usr/sbin/glusterfs is running. Version-Release number of selected component (if applicable): 3.4.2-1 How reproducible: Steps to Reproduce: 1./etc/init.d/nfs start 2.lsof -i:2049 3.kill the process who is using port of 2049 4.start nfs process Actual results: 1.Starting NFS daemon: rpc.nfsd: unable to bind inet TCP socket: errno 98 (Address already in use) 2.# lsof -i:2049 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME glusterfs 26965 root 12u IPv4 50016099 0t0 TCP *:nfs (LISTEN) 3.kill sucessfully 4.start sucessfully Starting NFS daemon: [ OK ] Expected results: 1.start sucessfully 3.kill sucessfully 4.start sucessfully Starting NFS daemon: [ OK ] Additional info:
This is expected behaviour. If you want to use the kernel NFS server or client on a Gluster storage server, make sure to disable the Gluster NFS server: # gluster volume set VOLUME nfs.disable true You should repeat that for all volumes. New volumes can have this option set before they get started.
