NFS problem

antonio elder prado — Wed, 26 Jan 2011 04:19:12 GMT

Hi,
i have the following nfs problem:
my nfs server is on a hpux 11.11.
i have two nfs exported files (let's say /a and /b)
they are mounted from different lvol on the server.
these nfs directories are the home directory for the nis accounts which has a server in another box.
this is where i do not understand:
- on /b and can login and can su to any user that has a home directory on /b
- on /a i cannnot do anything, if i try to su - user-on-a it hangs and never gets the prompt back.
this problems happens when i go from hpux 11.31, 11.23, 11.11 and 11.0; HOWEVER, this does not happens when i go from any aix, solaris or linux machines.
i did try to stop/restart the server. even reboot the server.

if you have any idea or clue of what is going on, please let me know.

thank you,
./antonio/.

Is the lock demon working on the server?
rpc.statd rpc.lockd

Hi,

Have you reviewed the mount options used. The "nfsstat -m" will tell you used options. Review ownership and permissions involved.

Check this document, could be useful:

Rgds.

hi Jose,

my nfssat -m looks like:

# nfsstat -m
/ocs from ulysses.tidalsoft.com:/home/ocs (Addr 10.88.103.182)
Flags: vers=3,proto=tcp,auth=unix,hard,intr,link,symlink,devs,rsize=32768,wsize=32768,retrans=5
All: srtt= 0 ( 0ms), dev= 0 ( 0ms), cur= 0 ( 0ms)

/ocs2 from ulysses:/home/ocsrd (Addr 10.88.103.182)
Flags: vers=3,proto=tcp,auth=unix,hard,intr,link,symlink,devs,rsize=32768,wsize=32768,retrans=5
All: srtt= 0 ( 0ms), dev= 0 ( 0ms), cur= 0 ( 0ms)

there is not difference between /ocs and /ocs2, where the ocs2 is the good and i have no problem on using as home directory for the nis accounts. when the /ocs is the crappy one.

thank you,

On both client and server?

hi Dennis,

yes on the server and on the clients.

strange, right, but the question is why one f.s. i have no problem with it and the other is no good...
still puzzled.

thank you,
