Hi Everybody,
I have AIX 4.3 and I have a FileSystem with 400GB size, which called /db/run. Because of grow up of the application's data, more storage has been added 200GB. To add this space without affecting the application & the application's requirements, I have to add this 200GB to the existed FileSystem /db/run. Using SMITTY I tried to increase the Size of the FileSystem /db/run. In fact, the SMITTY take a 100GB only so that the size of the /db/run FileSystem reached 500GB. When I told the problem to some friends, one of them said to me This is because of the limitation of your FileSystem.
When I asked him about the solution of this problem, he suggest as follow:

1. Backup the all data on that FileSystem.
2. Delete the FileSystem.
3. Create the FileSystem again but with PP Size that allow us to add whole 600G to it.
4. Finally, restoring the data from the backup was taken before.

So if this solution is true? If it is, could any body confirm the steps of this solution, and explain it in more detailed. If the suggested solution above is WRONG, could anybody help me to find out the ideal solution, where the FileSystem size increases to reach 600GB, without LOSING any Data was stored on the FileSystem before.
