AIX

I don't know AIX, but with the OS's I know unmounting the destination prior to running the dd is a must. I would unmount the source as well if I could. This is one of several reason why a dd in this case is not a great idea.

The belwo command did not work with me


and

The below command worked but after 3 hours finished but the data is not completed.
whole data in the source mount porint is 80% after finish the copying data came in the target mount porint as 30%


guy's

I'm looking for strong command dd or cp ... etc whatever I want to copy these huage data to the anothere mount porint ..



Pls advice ..

Compare number of files and directories instead of looking at df output.

If things still don't look right you might try installing the rsync rpm.

IBM AIX Toolbox Download Page - By Date

Syntax

Code:

rsync -a /sfsapp/ /tgtapp/

You can throw a -P in there which will show progress and a -n will give you a dry run to so you can see what it would look like before a real run. Also a -v if you want verbose output.

Please give me more information about

let me know , what will do it exactly ?

can anyone provide list of all the dd copy command options

This sounds quite suspicious. Could you please post the AIX version you are using (and, if applies, if you are using a 32-bit or 64-bit version?). This sounds like an older version not capable of dealing with files larger than 8G (ustar) or maybe hitting a 2G file size limit.

While you are at it: output of "ulimit -a" might also be interesting.

Hi Mr. AIX,

We'll find you a good command to copy your data but I'm a little concerned you're going to fill up your file system or something!

Let's make sure the basics are OK before we lump 250GB around.

Can you show the output of:

Code:

df -k /sfsapp
df -k /tgtapp
lsattr -El sys0 | grep realmem

The command you posted doesn't match the one the one juredd1 posted. This will do a test run of an rsync:

Code:

rsync -na /sfsapp/ /tgtapp
