It's a 4-drive Intel appliance, SS4200-EHW, so adding a disk for the journal is out of the question. It's only got 512MB ram ATM, (2GB max), so even fscking something that large (4.1T) could potentially fill up the RAM, not to mention it'd take hours. Thanks for the input though! --Brian -- _-=-_-=-_-=-_-=-_-=-_-=-_-=-_-=-_-=-_-=-_-=-_ Brian McCann "I don't have to take this abuse from you -- I've got hundreds of people waiting to abuse me." -- Bill Murray, "Ghostbusters"
