Known Issues On AIX Only

Cannot Create a Datastore Larger Than 1GB on AIX

On AIX, it may not be possible to create a datastore larger than 1 GB. This is due to a limitation on AIX: the default OS fsize limit on AIX is set to 2097151 blocks (1GB).

If you try to create a larger datastore using DXnewdsa or DXnewdb, you will see a message similar to the following:

$ dxnewdsa -s 2000 tmp 19689
Cannot write to datastore: File too large
Could not create new data store

Follow these steps:

  1. Check the value of ulimit, using the following command: 
    $ ulimit

    If the result is 2097151, your datastore size is limited to 1 GB.

  2. Set the fsize limit to unlimited with the following command: 
    chuser fsize=-1 dsa
