I am also getting "Out of memory for .." when trying to mke2fs. I
originally thought this was limited to a PowerPC, but I moved my raid
set to a PC and I get the same results.
My setup is a raid5 with three Ultra2 drives with 4GB each. I am using a
Symbios 53c895 chip with the alpha sym53c8xx driver. Using linux 2.2.1
and lates 012899 raid patches.
It seems as though the processor is outpacing the i/o and using up the
64MB of memory for buffers.
I am curious what configurations out there do work. Or maybe it would be
better to know which ones don't so it can get fixed.
