Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

Unable to mount shared folder from Linux server

Hi all,

I have 3 servers, rx2600, rx2600, and rx2660.

I have another x86 server running on Suse, and create a shared folder named /public

From 1 of the rx2600 server I can mount that shared folder :
Code:
intaqa:/>mount 10.1.2.82:/public /bkup
intaqa:/>cd /bkup

But from 2 others server I am unable to mount that shared folder :
Code:
intabck:/>mount 10.1.2.82:/public /bkup
NFS server 10.1.2.82 not responding still trying

In my Linux server the /etc/exports contains this line only :
Code:
/public 10.1.2.0/20(rw,sync,no_root_squash,no_all_squash)

intabck:/>ipfstat -io
empty list for ipfilter(out)
empty list for ipfilter(in)
intabck:/>

The ip address of others server :

rx2600 : 10.1.2.6 (intaqa) ----> this one can mount

rx2660 : 10.1.2.8 (intabck)

rx2800 : 10.1.2.4 (intadb)

rx2800 : 10.1.2.103 (intaaapp2)

and all can ping to 10.1.2.82
Code:
intabck:/>rpcinfo -p 10.1.2.82
rpcinfo: can't contact portmapper: RPC: Rpcbind failure - RPC: Failed (unspecifi

What should I check and change setting to solve this problem.

Thanks

looks like your NFS client are not running on both servers giving you trouble...
Why with the given info is uneasy to reply, I would start by looking at the system logs like rc.log ( to see if configured or not and if, errors? ), as it may be ( long time sine last time I touched an HP...) by default they are not..
It not configured the best is to use sam unless you know the way trough command line...

Having read your post a number of times I'm still very confused!!!

The /public NFS handle is published by 10.1.2.82, yes??

When you enquire the mounts available on 10.1.2.82 it says:
Quote:
intabck:/>showmount -e 10.1.2.82
export list for 10.1.2.82:
/public 10.1.2.8/24
intabck:/>
and from a different client:
Quote:
intaapp2:/>showmount -e 10.1.2.82
export list for 10.1.2.82:
/public 10.1.2.8/24
intaapp2:/>
So both are being told for /public go to 10.1.2.8/24

Can you please clarify what I'm missing. I just don't get that.

Yes the /public NFS is published by 10.1.2.82.
But I do not know why when it told for /public go to 10.1.2.8/24
As I know I can mount from server 10.1.2.6 but unable to mount it from 10.1.2.8, or 10.1.2.4, or 10.1.2.103

I have changed the exports file on the NFS server 10.1.2.82 and when I run the showmount command from client, it looks like this:
Code:
intabck:/var/adm>showmount -e 10.1.2.82
export list for 10.1.2.82:
/public 10.1.2.0/24

Maybe you have any suggestion to fix this problem?
Thanks

So if you issue command:

Code:
 
 # showmount -e 10.1.2.82

from 10.1.2.6 (the client that can successfully mount), does it give the correct answer?

---------- Post updated at 08:51 AM ---------- Previous update was at 08:45 AM ----------

I'm not a HP-UX expert (although I've used it a lot in the past) so I'm answering in generic terms only here.

I know that you are only referencing ip addresses here and not node names but, anyway, can you check all your /etc/hosts files and ensure that the ip addresses against all node names are correct (especially the one's on each node referring to itself).

I'll continue to scratch my head here.

Hi,

This is the result from 10.1.2.6:
Code:
intaqa:/>showmount -e 10.1.2.82
export list for 10.1.2.82:
/public 10.1.2.0/24

This the hosts file from 10.1.2.6
Code:
10.1.2.6        intaqa
10.1.2.4      intadb
10.1.2.22     intaqas
10.1.2.103    intaapp2
10.1.2.24     intaapp1
10.1.2.8      intabck
127.0.0.1       localhost       loopback
intaqa:/>

and this one from 10.1.2.8
Code:
10.1.2.4        intadb
10.1.2.103      intaapp2
10.1.2.6        intaqa
10.1.2.8        intabck
127.0.0.1       localhost       loopback
10.1.2.82       intalinux # fileshare

and this one from NFS server 10.1.2.82:
Code:
127.0.0.1       localhost

# special IPv6 addresses
::1             localhost ipv6-localhost ipv6-loopback

fe00::0         ipv6-localnet

ff00::0         ipv6-mcastprefix
ff02::1         ipv6-allnodes
ff02::2         ipv6-allrouters
ff02::3         ipv6-allhosts
