As I recall, Oracle gets even better performance if you just use a raw disk partition -- it is capable of managing block placement on a raw disk, and gets much better perfomance than by using the disk space through a filesystem driver.
That being said, if he decides to use the "whole disk" which includes the 1 or 2 blocks normally reserved for the partition table as part of his raw block device, he's just begging for data loss if the disk is ever removed from the system and put in another for some reason (hey! this partition table makes no sense -- that must be the problem -- I'll remake the first partition to use the whole disk...and wham, the first 512 - 1024 bytes are overwritten).
Next step, fire the sysadmin for not reading the logbook, o not making a disk image first :-p
I've seen crazy things happen. Especially during an outage, and they're trying to get a system back up. Under stress, people start forgetting obvious things. The best thing to do is to not set up each other for failure. The drawback to using the partition table and making the whole disk part of partition one is about a penny's worth of disk space. The drawback to having a mishap because someone forgot that the disk is using the partition table space for real data -- low end is probably hundreds of dollars. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
