Alter NDB Table

[Brian Abreu]

I am trying to alter a NDB table in mysql 5.1.11 in our testing environment. The table contains about 2GB of data; there is 3GB for data memory. I understand that in order to alter a table it must first be copied into a temporary table. When I attempt to add a column to the table, i get the error:

ERROR 1114 (HY000): The table '#sql-4530_57' is full.

I am guessing there is no way to add/remove columns without creating a temporary copy of the table. This is a problem because this test table is a small subset of a much larger production table (roughly 10GB) from another database. We are looking to migrate to mysql cluster, however, we need an efficient way of altering tables online (IE, the table cannot be write locked for several minuets while data is coppied). Does anyone have any suggestions/workarounds?
