Good morning,


    I'm trying to configure a cluster to use it as a backend to a radius
system, However I'm with a problem to import my database to it, when I
try to import, I get the following error:

ERROR 1114 (HY000) at line 3818: The table 'radacct' is full

Here is my config.ini:

I've asked it sometime ago at the freeradius user list, they told me
that my cluster could be full, but I don't know how to tell if my
cluster is full, in theory the 2 data nodes have enough RAM to host the
database (This database is 3.9GB).
