Excellent point. The added latency can allow a lazy journal to nuke the transaction. > SCSI or even better a *good* hardware RAID controller. The real problem with proffering advice here is that we don't know his loading. Without some idea of his mail volumes and delivery targets (if he's lucky the majority will be local LAN) its really tough to say what he'd need for hardware. Still, I do like the Mylex DAC960 cards... > Filesystems are a religious issue but I still keep hearing more > mentions of resiserfs going completely tits-up for my liking. Great > ideas but there still seem to be some problems there..... I can't comment well to this other than to note that I've been running ReiserFS almost exclusively (I've generally left / and /boot as ext2, but that's less than 128Meg combined) for a couple years now on my list servers, desktops, web servers, etc. I had one problem in the early months which may have been exacerbated or caused by a failing drive and a known-bad kernel (the TLB IPI wait bug).
