NFS server daemon dies

[Bharat Katkar]

Hello everybody,
I have an Hp server (which is a nisplus client) and when i try logging in to HP server with NIS user i am not able to get home directory. Home directory is NFS mounted. We have linux server which is a NFS server. It works fine for all others (except HP).
We are mounting /home of linux server to /lhome of HP server.
On HP server i have files as follows:
1./etc/auto_master
/lhome auto.Linuxserver
2./etc/auto.Linuxserver
* -rw,rsize=8192,wsize=8192,tcp linuxserver:/home/&

I have set /etc/rc.config.d/nfsconf file as follows:
NFS_CLIENT=1
NFS_SERVER=1
NUM_NFSD=16
NUM_NFSIOD=16
PCNFS_SERVER=0
START_MOUNTD=1
AUTO_MASTER="/etc/auto_master"
AUTOFS=1
AUTOMOUNT_OPTIONS=""
AUTOMOUNTD_OPTIONS=""

DO i have to do anything else. Linux server is working fine & serving properly for all other servers.
Still i don't understand why the mountd daemon on linux server get hanged whenever NFS mount request is done by the HP machine.

I am using 11i and RP2600 server.
Any expert comments please.
Thanks in advance.

Things to check.

1. are you up to date on NFS patches on HP-UX?
2. NFS versions Linux and Hp-Ux using? Are they same? if not You can match linux version while mounting dir with -vers option on mount command.
3. From HP-UX, does showmount -e linux_server resturns OK?

Thanks Anil for your reply.
I tried this things:
# showmount -e vcslnxb3
showmount: vcslnxb3: RPC: Miscellaneous tli error - bad flags
# ping vcslnxb3
PING vcslnxb3.vxindia.veritas.com: 64 byte packets
64 bytes from 10.212.99.244: icmp_seq=0. time=0. ms
64 bytes from 10.212.99.244: icmp_seq=1. time=0. ms

Also i do check NFS versions on linux server.
Also how do i check whether NFS patches are UPDATED or not.

Thanks,
Bharat

Anil,
I am attaching the "nfsstat" output. See if you can make something from that.
Thanks,

On client side, there are bad calls in nfsstat output. But that is understood -as you have problems with hp-ux nfs mounts from linux nfs server.

How may clients this linux server serves? (NFS clients) As on HP-UX, can you set no. of NUM_NFSD and NUM_NFSIOD on linux side? (linux equivalents of those)

Depending on how many clients, linux server serves, you can increase the count.

Also on HP-UX, do you have any messages in dmesg an syslog. DLI error messages can come when, there is a probem in server client RPC communication.

For NFS patches, check itrc and search for nfs pacthes and check, if you have those.

In the HP server,
- Do a showmount -a to see the mounted hosts.
- Check if processes rpc.mountd and nfsd are running.
- Edit the /etc/exports file to include the export directories
Hope this helps
