What is the purpose/effect of the &ie=utf-8&oe=utf-8 in that link?

EDIT: and of the client=ubuntu?

@brownie_cookie: this Google search lists many pages with your error message. Have you tried re-starting the NFS daemons? If so how and what was the output/effect?

that's all i got... so does that mean there aren't any mounts on this host?

It looks as if the NFS daemons were not running. What happens if you run showmount after re-starting the NFS daemons like that?

can someone pls help me?

catkin 05-11-2011 02:13 AM
AFAIK showmount gets its data from /var/lib/nfs/rmtab. Do you have anything in that file? BTW, the rpc.mountd man page says this about it:
Code:
  The rmtab File
      For  every  mount  request  received from an NFS client, rpc.mountd adds an entry to the /var/lib/nfs/rmtab file. When
      receiving an unmount request, that entry is removed.

      However, this file is mostly ornamental. One, the client can continue to  use  the  file  handle  even  after  calling
      rpc.mountd's UMOUNT procedure. And two, if a client reboots without notifying rpc.mountd , a stale entry will remain
      in rmtab.

brownie_cookie 05-11-2011 02:34 AM
no, i have nothing in those files. So that's why he doesn't show anything..
hmmm

i'm confused, i KNOW that i have NFS mounts, becuase when i do
Code:
mount
i get a lot of feedback
Code:
/dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/cciss/c0d0p1 on /boot type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
ip:/CVBDISK on /CVBDISK type nfs (rw,addr=ip)
hostname:/VOLUME1/PUBLIC on /nasdisk4 type nfs (rw,addr=ip)
/dev/ram0 on /ramdisk type ext2 (rw)
nfsd on /proc/fs/nfsd type nfsd (rw)
i just need to know WHAT my mount (or mountpoints) ARE
i DON'T need to know what size they are and all that stuff, i just need to know the names

Do you mean you want to know the device file names for NFS file systems that your computer has mounted as an NFS client from NFS servers? If so, showmount is the wrong command because it shows the NFS clients of your computer's NFS service. One way would be to run df --type=NFS and parse the output.

brownie_cookie 05-11-2011 04:28 AM
okay, i do this

Code:
# df --type=nfs
Filesystem            1K-blocks      Used Available Use% Mounted on
ip:/CVBDISK            143364032 132783712  10580320  93% /CVBDISK
host:/VOLUME1/PUBLIC  1452397728 1111896352 340501376  77% /nasdisk4
so this means, those 2 are the mounts for my server?
and with mounts i mean links with another server

Yes -- your computer, as an NFS client, has mounted those NFS file systems from those NFS servers (I presume you have changed the actual hostname to host and the actual IP address to ip).

chrism01 05-11-2011 07:01 PM
Those are NFS mounts where this system is an NFS client.
The prev NFS start/stop/showmount cmds should only be run on an NFSserver.
You should shutdown those NFS services again unless you intend to be a server.

You should find this well explained here http://www.linuxtopia.org/online_boo...ion/index.html.
Please add your distro to your profile for more accurate help

can you show me the command to be sure of what distro i'm using?
normally it is RHEL 4, but somebody showed me a command and appearently i have CentOS... so i'm not sure anymore..

chrism01 05-12-2011 01:03 AM
Code:
cat /etc/*release*

uname -a
The first is more appropriate here; the 2nd is really the kernel version

brownie_cookie 05-12-2011 01:17 AM
Code:
# cat /etc/*release*
CentOS release 5.5 (Final)
Code:
# uname -a
Linux host 2.6.18-194.32.1.el5 #1 SMP Wed Jan 5 17:53:09 EST 2011 i686 i686 i386 GNU/Linux
so i geuss i have a CentOS ;)

Do you have a problem with the solution suggested in this post?

brownie_cookie 05-13-2011 12:53 AM
so you mean this
Code:
df --type=NFS
so, then i'm sure that the result of this command will show ONLY the NFS mounts?

(just to be sure)

From the df man page:
Code:
      -t, --type=TYPE
              limit listing to file systems of type TYPE

brownie_cookie 05-13-2011 01:24 AM
so i geuss you mean i can be sure ... :)
