Problems trying to mount a nfs (server: linux, client: AIX 4.2)
Last modified: 2008-05-01 11:37:51 EDT
Tested with: RedHat Linux/i386 6.0 and RedHat Linux/sparc 6.0 (bet it happens on the other archs too) Kernel: 2.2.11 NFS Package: knfsd-1.2.2-4 Lets suppose linux1.mydomain is a sparc machine, and linux2.mydomain is an i386 machine. When it works: linux1# mount linux2:/home /mnt linux2# mount linux1:/home /mnt linux1# mount aix1:/home /mnt linux2# mount aix1:/home /mnt aix1# mount aix2:/home/mnt When it does not work: aix1# mount linux1:/home /mnt aix1# mount linux2:/home /mnt I get the following error message: aix1# mount linux1:/home /mnt mount: 1831-010 server linux1 not respondingmount: retrying linux1:/home But, as you can see, the service is running: aix1# rpcinfo -p linux1 program vers proto port service 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 989 status 100024 1 tcp 991 status 100011 1 udp 1000 rquotad 100011 2 udp 1000 rquotad 100003 2 udp 2049 nfs 100021 1 udp 1026 nlockmgr 100021 3 udp 1026 nlockmgr 100021 1 tcp 1024 nlockmgr 100021 3 tcp 1024 nlockmgr 300019 1 tcp 622 300019 1 udp 623 100005 1 udp 873 mountd 100005 1 tcp 875 mountd 100005 2 udp 878 mountd 100005 2 tcp 880 mountd 100005 3 udp 883 mountd 100005 3 tcp 885 mountd And I have all I need on my aix machine: aix1# rpcinfo -p 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 udp 2049 nfs 100003 3 udp 2049 nfs 100003 2 tcp 2049 nfs 100003 3 tcp 2049 nfs 200006 1 udp 2049 200006 1 tcp 2049 100005 1 udp 1084 mountd 100005 2 udp 1084 mountd 100005 3 udp 1084 mountd 100005 1 tcp 1025 mountd 100005 2 tcp 1025 mountd 100005 3 tcp 1025 mountd 100024 1 udp 733 status 100024 1 tcp 735 status 200001 1 udp 739 200001 1 tcp 745 200001 2 tcp 745 100021 1 udp 1125 nlockmgr 100021 2 udp 1125 nlockmgr 100021 3 udp 1125 nlockmgr 100021 4 udp 1125 nlockmgr 100021 1 tcp 1026 nlockmgr 100021 2 tcp 1026 nlockmgr 100021 3 tcp 1026 nlockmgr 100021 4 tcp 1026 nlockmgr So, I wonder why I does not work. Any tips ? Any other test ? Anything else I haven't checked ? Tkx
More information about the tests I performed: linux1# who rodrigob pts/0 Aug 25 17:23 (aix1.mydomain) aix1# showmount -e linux1 export list for linux1: /home aix1.mydomain,linux2.mydomain These are working. No clues about any other test I can perform.
Try the latest knfsd-1.4.7 package from Raw Hide. You should probably also install and run the latest kernel-2.2.11 package because of the knfsd version specific patches in the kernel. I suspect what's broken is the (broken!) NFSv3 service that the knfsd-1.2.2 daemon advertises. You might check in /etc/rc.d/init.d/nfs and make sure that you are starting rpc.mountd with --no-nfs-version 3 Please reopen this bug if the above does not fix your problem. a
