It slows down every single request, and is not necessary. See here for a better way of displaying hostnames instead of the IPs found in the log files: http://help.directadmin.com/item.php?id=27 Hi,

It is the best I have found about how to install the raid. I have succeeded in making it work in my computer, except for the times when I halt it. I don't know why, when I reboot it works perfectly good, but when halting the machine my disks are shown by the bios as "offline member" and no OS is found. The only way to start it then is to load up the live cd and making a reboot from there, which corrects the problem until the next halt. Any ideas on how to fix this?
