two way synchronization

[rudy]

I tried some different setups, but I can't get it two work.
Replication gives no errors, but synchronization doesn't work right.

nas1:
path : /lv0000/www
share name : /www

nas2:
path : /lv0000/www
share name : /www

enabled replication on both shares.

Files aren't replicated in the right way.
When I add some files tot nas1 and to nas2 at the same time, the synchronization goes wrong. Files are placed on the other server, but the files I placed orginally aren't there anymore.

Could you give me the right configuration for this setup?
I also tried the setup you recommended, but I think I'm doing something wrong.
Isn't there any documentation how to solve these problems?

Set the nas2: (Destination Server) first.
path : /lv0000/www
share name : /www
Enable the Data replication agent:
CONFIGURATION -> NAS settings -> Function: Data replication agent.
Then enable the Data replication agent for the share:
SETUP -> NAS resources -> Shares -> [share_name] -> Function: Data replication agent settings.


nas1: (Source Server)
path : /lv0000/www
share name : /www

Assign Snapshot to lv0000 (located in Volume Manager)
Go to Maintenance / Backup / Data Replication
Select Snapshot (lv0000)
Set Data Replication schedule (Now, Interval or scheduled)

This is one way synchronization...

Isn't it possible to setup a two synchronize both servers. So when I put some files on nas1 the files are synct to nas2, and when I add some on nas2 the files are put on nas1?...

[To-M]

Yes but not on the same share going back to NAS1.

Ok, now I understand.

How do I setup a high availabilty setup with two NAS R3 servers?
Is there anything to automaticaly take over first server if it fails?

I saw bonding, but the take over isn't immediately.
What do you recommend?

[To-M]

We do not have Automatic failover in our NAS-R3 (DSS will have this near November this year for the NAS - not sure for NAS-R3). If using Microsoft you can use there clustering feature. If using NFS mounts simply remount to the second NAS share.
If using a bonding I would recommend Balance RR.


Update to Auto Failover!!

Please be advised that Auto-Failover has been delayed - there is no set date or details related to this subject.
We will announce this at a later date. Thank you for your patience on this matter.
