Description Terry Riley 2005-06-23 15:34:35 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Description of problem:
nfs mount hangs at boot with this message:
RPC: Error 5 connecting to server [servername]

and then, after a few minutes:
mount: [servername:/mountpoint] can't read superblock

boot eventually continues without nfs mounts;
mount -a after boot will mount nfs directories some of the time

Version-Release number of selected component (if applicable):
nfs-utils-1.0.7-8; kernel-2.6.11-1.1369_FC4

How reproducible:

Steps to Reproduce:
1.configure nfs client
2.reboot client

Actual Results:  boot hangs at nfs mount

Expected Results:  boot completes nfs mounts

Additional info:

Server is FC3 (2.6.11-1.27_FC3) with nfs-utils-1.0.6-52

Client is using the same /etc/fstab nfs config that worked prior to upgrade from FC3 to FC4:

zippy:/home             /home                   nfs     rw,rsize=8192,wsize=8192 0 0

client /usr/sbin/rpcinfo -p
   program vers proto   port
    100000    2   tcp    111  portmapper
    100000    2   udp    111  portmapper
    100024    1   udp  32768  status
    100024    1   tcp  32769  status
    100021    1   udp  32771  nlockmgr
    100021    3   udp  32771  nlockmgr
    100021    4   udp  32771  nlockmgr
    100021    1   tcp  32784  nlockmgr
    100021    3   tcp  32784  nlockmgr
    100021    4   tcp  32784  nlockmgr

Several FC3 clients are nfs-mounting server without problems.

Same problem here. I see some activity on NFS issues in fedora-list as well.

For reference I switched off selinux, no change. I am exporting home directories
from my server to my local net, . I also happen to be using
firestarter on my server as my firewall interface, using the dhcp function, and
I notice that even if I shut off a machine, it is still shown as an active nfs
connection. If I restart NFS services on the server, the active connection is
dropped, and then my workstation machine will boot correctly and import the NFS
home export.

Comment 2 Steve Dickson 2005-07-08 11:57:09 UTC
Would it be possible to get an b2zip-ed binary ethereal trace
(i.e. on the client 'tethereal -w /tmp/data.pcap host server')?

Comment 3 John Thacker 2007-03-10 18:46:40 UTC
Closing because bug has remained in NEEDINFO state without reply for a long
period of time.

Note that FC3 and FC4 are supported by Fedora Legacy for security
fixes only.  Please install a still supported version and retest.  If
it still occurs on FC5 or FC6, please reopen and assign to the correct
version.  Otherwise, if this a security issue, please change the
product to Fedora Legacy.  Thanks, and we are sorry that we did not
get to this bug earlier.

This bug was originally filed against a much earlier version of Fedora
Core, and significant changes have taken place since the last version
for which this bug is confirmed.
