(In reply to Steve Dickson from comment #8) > Does this happen client and server are on different machines? Yes, here is example between 2 VMs, client is RHEL6, server is RHEL7. Client starts nfs.service over ssh and tries to mount. Mount immediately following 'service nfs start' fails, the same mount works after 2 second delay: # cat client.sh umount /mnt/test &> /dev/null ssh root.27.145 "service nfs stop" sleep 2 ssh root.27.145 "service nfs start" echo "service nfs start on server returned $?" mount -v -t nfs -o nfsvers=3 10.34.27.145:/export /mnt/test echo "mount returned $?" rpcinfo -p 10.34.27.145 sleep 2 mount -v -t nfs -o nfsvers=3 10.34.27.145:/export /mnt/test echo "mount after sleep returned $?" rpcinfo -p 10.34.27.145 # . client.sh root.27.145's password: Redirecting to /bin/systemctl stop nfs.service root.27.145's password: Redirecting to /bin/systemctl start nfs.service service nfs start on server returned 0 mount.nfs: timeout set for Mon Sep 23 11:48:12 2013 mount.nfs: trying text-based options 'nfsvers=3,addr=10.34.27.145' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 10.34.27.145 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: portmap query retrying: RPC: Program not registered mount.nfs: prog 100005, trying vers=3, prot=6 mount.nfs: portmap query failed: RPC: Program not registered mount.nfs: requested NFS version or transport protocol is not supported mount returned 32 program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100003 2 tcp 2049 nfs 100227 2 tcp 2049 nfs_acl 100003 2 udp 2049 nfs 100227 2 udp 2049 nfs_acl 100024 1 udp 40707 status 100024 1 tcp 42206 status 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100227 3 tcp 2049 nfs_acl 100003 3 udp 2049 nfs 100003 4 udp 2049 nfs 100227 3 udp 2049 nfs_acl 100021 1 udp 38835 nlockmgr 100021 3 udp 38835 nlockmgr 100021 4 udp 38835 nlockmgr 100021 1 tcp 41805 nlockmgr 100021 3 tcp 41805 nlockmgr 100021 4 tcp 41805 nlockmgr 100011 1 udp 875 rquotad 100011 2 udp 875 rquotad 100011 1 tcp 875 rquotad 100011 2 tcp 875 rquotad mount.nfs: timeout set for Mon Sep 23 11:48:14 2013 mount.nfs: trying text-based options 'nfsvers=3,addr=10.34.27.145' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 10.34.27.145 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 10.34.27.145 prog 100005 vers 3 prot UDP port 20048 10.34.27.145:/export on /mnt/test type nfs (rw,nfsvers=3) mount after sleep returned 0 program vers proto port service 100000 4 tcp 111 portmapper 100000 3 tcp 111 portmapper 100000 2 tcp 111 portmapper 100000 4 udp 111 portmapper 100000 3 udp 111 portmapper 100000 2 udp 111 portmapper 100003 2 tcp 2049 nfs 100227 2 tcp 2049 nfs_acl 100003 2 udp 2049 nfs 100227 2 udp 2049 nfs_acl 100024 1 udp 40707 status 100024 1 tcp 42206 status 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs 100227 3 tcp 2049 nfs_acl 100003 3 udp 2049 nfs 100003 4 udp 2049 nfs 100227 3 udp 2049 nfs_acl 100021 1 udp 38835 nlockmgr 100021 3 udp 38835 nlockmgr 100021 4 udp 38835 nlockmgr 100021 1 tcp 41805 nlockmgr 100021 3 tcp 41805 nlockmgr 100021 4 tcp 41805 nlockmgr 100011 1 udp 875 rquotad 100011 2 udp 875 rquotad 100011 1 tcp 875 rquotad 100011 2 tcp 875 rquotad 100005 1 udp 20048 mountd 100005 1 tcp 20048 mountd 100005 2 udp 20048 mountd 100005 2 tcp 20048 mountd 100005 3 udp 20048 mountd 100005 3 tcp 20048 mountd *** This bug has been marked as a duplicate of bug 963138 *** |
