Subj : NFS problems. Please help To : comp.os.linux From : Val Date : Thu Aug 26 2004 03:15 am Subject: NFS problems. Please help From: Val Newsgroups: alt.linux Date: Thu, 26 Aug 2004 01:58:57 GMT Hi. I just got back from a long trip only to find that almost all functionality on my home network is gone. Unfortunately, I can't remember the exact change or moment in time when this started happening, so I must now deal with what I see. I can still mount all the volumes and I can browse the remote volumes. However, copying any file results in small burst transfers with very large delays between the bursts. 1M file takes minutes to copy. I have established that this is not a cable/switch problem, since scp and everything else still performs as it should. There are no error messages on the server in either /var/log/messages or dmesg On the client dmesg gives these errors: nfs: server datahost not responding, still trying nfs: server datahost OK nfs: server datahost not responding, still trying nfs: server datahost not responding, still trying nfs: server datahost OK nfs: server datahost OK -- repeats ---- The server is configured as follows: Kernel 2.6.1 nfs-utils 1.0.6 val@datahost:~$ rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 391002 1 tcp 623 sgi_fam 391002 2 tcp 623 sgi_fam 100005 1 udp 629 mountd 100005 1 tcp 632 mountd 100005 2 udp 629 mountd 100005 2 tcp 632 mountd 100005 3 udp 629 mountd 100005 3 tcp 632 mountd 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100021 1 udp 32768 nlockmgr 100021 3 udp 32768 nlockmgr 100021 4 udp 32768 nlockmgr 100024 1 udp 32770 status 100024 1 tcp 32771 status 100011 1 udp 638 rquotad 100011 2 udp 638 rquotad 100011 1 tcp 641 rquotad 100011 2 tcp 641 rquotad val@datahost:~$ cat /etc/exports /data/music 192.168.0.0/255.255.255.0(no_root_squash,rw) /data/video 192.168.0.0/255.255.255.0(no_root_squash,rw) /data/programs 192.168.0.0/255.255.255.0(no_root_squash,rw) /data/work 192.168.0.0/255.255.255.0(no_root_squash,rw) /usr/home 192.168.0.0/255.255.255.0(no_root_squash,rw) val@datahost:~$ cat /etc/hosts.allow portmap: 192.168.0.0/255.255.255.0 lockd: 192.168.0.0/255.255.255.0 rquotad: 192.168.0.0/255.255.255.0 mountd: 192.168.0.0/255.255.255.0 statd: 192.168.0.0/255.255.255.0 val@datahost:~$ cat /etc/hosts.deny portmap:ALL lockd:ALL rquotad:ALL statd:ALL The client is configured as follows: Kernel: 2.6.3 nfs-utils 1.0.6 root@boss:~# mount --version mount: mount-2.12a root@boss:~# rpcinfo -p program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 32768 status 100024 1 tcp 32768 status 100021 1 udp 32769 nlockmgr 100021 3 udp 32769 nlockmgr 100021 4 udp 32769 nlockmgr 391002 1 tcp 949 sgi_fam 391002 2 tcp 949 sgi_fam root@boss:~# rpcinfo -p datahost program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 391002 1 tcp 623 sgi_fam 391002 2 tcp 623 sgi_fam 100005 1 udp 629 mountd 100005 1 tcp 632 mountd 100005 2 udp 629 mountd 100005 2 tcp 632 mountd 100005 3 udp 629 mountd 100005 3 tcp 632 mountd 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100021 1 udp 32768 nlockmgr 100021 3 udp 32768 nlockmgr 100021 4 udp 32768 nlockmgr 100024 1 udp 32770 status 100024 1 tcp 32771 status 100011 1 udp 638 rquotad 100011 2 udp 638 rquotad 100011 1 tcp 641 rquotad 100011 2 tcp 641 rquotad root@boss:~# mount --- other stuff here --- datahost:/data/music on /mnt/datahost/music type nfs (rw,addr=192.168.0.11) datahost:/data/video on /mnt/datahost/video type nfs (rw,addr=192.168.0.11) datahost:/data/programs on /mnt/datahost/programs type nfs (rw,addr=192.168.0.11) datahost:/data/work on /mnt/datahost/work type nfs (rw,addr=192.168.0.11) datahost:/usr/home on /mnt/datahost/homes type nfs (rw,addr=192.168.0.11 I can't find anything wrong with this setup. Any ideas would be greatly appreciated. Thank you for your time. Val .
