share folder between two systems

jagdip · 09-17-2012, 08:51 PM

I need to set up shared directory between two solaris systems running 10.9. i have licenses for vxfs file systems also. what will be the best way to share folder between these two systems? is there something offered by vxfs file system which has advantage?

Use NFS.

Assuming the directory you want to share is /data/shared-directory, on the server side, run:

Code:

mkdir /data/shared-directory
chmod 04777 /data/shared-directory
echo "share -F nfs -o rw /data/shared-directory" >> /etc/dfs/dfstab
svcadm enable -r nfs/server

On the client side (replace server1 by the first server IP address)

Code:

mkdir /data/shared-directory
echo "server1:/data/shared-directory - /data/shared-directory nfs - yes rw,soft" >> /etc/vfstab
mount /data/shared-directory

Thank you.

can i use this NFS share on server and client at the same time? in other words, i will be using server1 as NFS server and server2 as NFS client but both server1 and server2 can read write to NFS at the same time.

You definitely can, that wouldn't be a share otherwise.

Thank you. only problem with this design is that if NFS server goes down, NFS client will not have access to shared folder. because one node is acting like as NFS server and other is acting as client, it defeats the purpose of sharing folder as shared folder is only required to host some libraries of clustered software. those libraries will not be available to second node if first goes down ( acting as NFS server ) because second has no NFS share and it can not come up.

are there any other ways ?

It doesn't unless you demand an highly-available shared folder which you didn't state in your initial question.

HA solutions require a shared device and a file system supporting concurrent OS access natively like QFS, or a regular file system like UFS or VXFS with the global mount option (Sun Cluster).

Thanks.
I can look into VxFS with global mount. Do i need to configure Veritas Storage Foundation Cluster with heartbeat links and fencing disks before i create VxFS with global mount?
Can you direct me to some online resources?

Sorry, but I'm afraid I'm not familiar enough with Veritas and clustering software in general to be more helpful here.
