you can monitor the task from the task list,

use the command: nas_task -list , check the one time replication session task.

Well this just gives me the status. I need the information so that I can decipher how much time I would need in the future to migrate a file system of a certain size..

Server_log

Hello Naveen

You can use this command to check the information about the initial copy running. The oupput will give you an estimated time to complete,Percentage complete etc.

nas_task -info {-all | task ID }

Please let us know if this command has provided you the desired information that you were looking for.

Thanks

Does this work if the task is says succeeded in the task state column?  Coz all I get from this command output is the start time, end time and some other related info, but not what I am looking for. The replication is still going on though.

This is the output I get out of a nas_task -info for the replication session that I am running.

[nasadmin@XXXX ~]$ nas_task -info 531744

Task Id                = 531744

Celerra Network Server = 0

And this is the output from nas_replicate

I still do not have something that shows me estimated time to complete or how much data is left to transfer.

Hello Naveen

Looking at the output of the nas_replication command it seems that the initial copy has completed and as mentioned by bergec the sorce and destination will now try to be in sync with a time difference of less than1 0 minutes (Max Out of Sync Time (minutes) = 10) you can also check the data transferred to the destination by comparing the source and destination file system size (nas_fs -size ).

In your case it seems that the replication session creation process has completed with the completion of initial copy. Now the source and destination File system will try to be in sync.

Thanks
