hi
i m working as a linux administrator in a software comapny. i have a task to nfs configuration. i m using slackware linux. i configruation two nfs server and using static ip. i exported a directory such as /data in one nfs server1 and another is /tmp in nfs2 server. i want to configure such that when some directory or file will create in /data directory, the files will show the other nfs server /tmp dirctory and vice versa.

the configuration of two nfs server
one nfs server ip address is 192.168.1.1
#vi /etc/exports
/data 192.168.1.2(ro,sync)
:wq
#exportfs -av
#/etc/rc.d/rc.nfsd restart

another nfs server is 192.168.1.2
#vi /etc/exports
/tmp 192.168.1.1(ro,sync)
:wq
#exportfs -av
#/etc/rc.d/rc.nfsd restart

then i have entry in first nfs server /etc/fstab file
192.168.1.2:/tmp /data nfs defaults 0 0
:wq

then i entry in 2nd nfs server /etc/fstab file
192.168.1.1:/data /tmp nfs defaults 0 0
:wq

after that i tried mount -a in 1st nfs server
it ran well. the file of 2nd nfs server is showing in 1st nfs server data directory.but when i m running mount -a in 2nd nfs server, a error message is display i.e. mount: 192.168.1.1:/data failed, reason given by server: Permission denied.


plz help me and give me any idea how to configure these two nfs server mapping each other.

for god's sake, please use clear words ?

Hello amitk_m,

NFS can be frustrating. Please check some things for us.

Verify that the portmapper service is running on both machines.

Also change the /etc/exports/ from:

to

It appears that you have them set for ro, or Read Only.

Just suggestions as always. Once you make the changes in /ext/exports be sure to reexport and restart all services related.

This a great article for troubleshooting NFS issues. It has helped me many of times.

Also can you please provide the last 50 lines of /var/log/messages after you run the command to re export.


Good Luck,

Jaysunn

From his words i understand that he req some NFS cluster or some thing.. where two nfs server are working to share same data..
or if he really want to use two server with two diff share and want to see the same data means he can use rsync utility for this purpose... What you say nixcraft?
