NFS server

SlacUser · 05-11-2007, 11:27 AM

Hi I'm trying to implement a NFS server, to share some files with certain clients.

Everything works fine, I made a test and I can mount my /home directory, but what I want to do, is to share a primary partition of 20 gb. What do I need to do for that?

I already did a test, setting the /dev/sda4 in my exports file, but the client doesn't recognize it as a directory. I think I have to do an special step to share it.

This is my partition table:
Disk /dev/sda: 72.7 GB, 72729231360 bytes
255 heads, 63 sectors/track, 8842 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 1 124 995998+ 82 Linux swap
/dev/sda2 * 125 248 996030 83 Linux
/dev/sda3 249 5477 42001942+ 5 Extended
/dev/sda4 5478 8031 20515005 83 Linux
/dev/sda5 249 497 2000061 83 Linux
/dev/sda6 498 746 2000061 83 Linux
/dev/sda7 747 4481 30001356 83 Linux
/dev/sda8 4482 5477 8000338+ 83 Linux

If you want to share a partition, just mount that partition as a directory, then just share that directory. So you would have in your /etc/fstab something like

Code:

/dev/sda1        /mnt/fat         vfat         noauto,user,rw   0   0

then in /etc/exports you would have something like

Code:

/mnt/fat/ *(async,all_squash)

Then you could mount from client machines with

Code:

#mount 192.168.1.*:/mnt/fat /mnt/dir

Of course you would be using your relevant information.

I can't mount the device, Am i doing something wrong??

Code:

root@iet:~# mount /dev/sda4
mount: can't find /dev/sda4 in /etc/fstab or /etc/mtab

Could be that is a primary partition??
and it is totally clean, I've just create it in order to share it.

You need to mount it somewhere to share it. You should NOT share /dev/sda4, or /dev/anything else. That refers to the device itself, rather than the files on its filesystem.

Instead, you'll mount the filesystem somewhere like /shares/sda4, and THAT is the directory you'll share. The steps are:

1) Create an empty directory somewhere for the mounting point (e.g. mkdir /shares/sda4)

2) Add an entry for the partition in /etc/fstab (e.g. vi /etc/fstab)

The details of this fstab entry depend on what file system it is and exactly what you want to do with it.

3) Mount the partition with mount /shares/sda4

Then, after it's mounted you can export it.
