Description R.H. Ruskin 2004-10-20 23:46:57 EDT
Description of problem: NFS problems. I am trying to mount a file located on the machine "lion". The directory is /cheetah. The NFS compunets located on both "bobcat" and "lion" are running. I have no problem mounting /cheetah from "jaguar". The command is mount lion:/cheetah /cheetah. From "jaguar" a df shows that /cheetah has been mounted and can be read. When I issue the same command from "bobcat" I get the following message: "mount to NFS server 'lion' failed: server is down." Yet if I issue the command "mount zuni:/sgi /cheetah" which is located on a remote server, not only does /cheetah mount -- as can be seen when I issue a df command -- but all the files casn be broused both from my end as well as from the remote server end. Version-Release number of selected component (if applicable): Fedora Core 2 /64 How reproducible: Every time. Steps to Reproduce: 1. From "jaguar": mount lion:/cheetah /cheetah 2. From "bobcat": mount lion:/cheetah /cheetah 3. Actual results: ?cheetah mounts from "jaguar" but not from "bobcat" Expected results: lion:/cheetah *should* mount from "bobcat". Additional info: I can ping all my machines ("jaguar", "lion", "bobcat") from any of the other machines on my network and I can ping remote machines not on my network from any of the machines on my network.

Could you post an ethereal trace of this? Also what does mount -v show as far as the RPC error?
Comment 2 R.H. Ruskin 2004-10-21 14:42:57 EDT
Results of Etheral trace: I pinged lion (from "bobcat") then stared the trace. Here is what I got: I ran the trace for ~ 2 minutes most of the Protocols listed are ICMP. The source/ request shows up as 192.168.1.4 ("bobcat") and the Distination shows as 192.168.1.2 ("lion"). The source / reply shows as 192.168.1.2 ("lion") and the destination as 192.168.1.4 ("bobcat"). I have two other protocols that show up every once in a while: one protocol is marked NTP marked 192.168.1.6 ("jaguar" [the third computer on my network]) and goes to 126.96.36.199 (off my network). The third protocol is marked ARP. Below that I get the following message: > Frame 1 (98 bytes on wire, 98 bytes captured) > Ethernet II, Scr: 00:20:18:56:df:5f , Dst: 00:50:ba:ee:bc:d6 > Internet Protocol, Scr.

what is the output of rpcinfo -p lion

Comment 5 R.H. Ruskin 2004-10-24 08:00:50 EDT
Want to pass this on, my buddy found this command somewhere on the net and it works. Thanks for your interest in my problem. Hoope this will help others who may be facing the same problem as I. mount -o nfsvers=2 lion:/cheetah /cheetah
Comment 6 Steve Dickson 2004-11-02 14:49:14 EST
The mountd on lion should be logging some reason (in /var/log/messages) as to why its not allowing mounts from cheetah....
Comment 7 Robert Buffington 2005-03-31 17:23:59 EST
This should now be moved to Fedora Core (fc3) as of Mar 31 because apparently a yum update, perhaps util-linux-2.12a-21, broke NFS mounts from our Linux RHL9-legacy (nfs-utils-1.0.1-3.9) server. No other changes to our NFS server were made, and other same-level Linux systems can still mount filesystems with no problems from the server. Using nfsvers=2 seems to have no effect for me. There also seem to be no messages logged (as mentioned in comment #6) in our server's /var/log/messages. # mount -v /var/spool/mail mount to NFS server 'hostx' failed: server is down. RPC Error: 0 ( Success ) # mount -t nfs -o nfsvers=2 hostx:/opt/net/mail /var/spool/mail mount to NFS server 'hostx' failed: server is down.
Comment 8 Steve Dickson 2005-03-31 21:41:27 EST
I believe this is duplication of bz152956. Would you mind trying the util-linux that is in http://people.redhat.com/steved/bz152956 to see if it fixes the problem
Comment 9 Robert Buffington 2005-04-01 14:25:17 EST
Yes - this worked. And you're right, this one should be marked as a duplicate of 152956. This is in fact a util-linux problem and has nothing to do with nfs- utils, even though it's NFS-related. Thanks for your reply!
