Well, I've set up one of our new JetStors. xfs took *seconds* to put a filesystem on it. We're talking what df -h shows as 66TB. (Pardon me, my mind just SEGV'd on that statement....) Using bonnie++, I found that a) GPT and partitioning gave was insignificantly different than creating an xfs filesystem on a raw disk. I'm more comfortable with the partition, though. b) There was a small but significant difference if, when I created the filesystem, if I gave sw and su in the mkfs.xfs command. I do have a question for the group mind, though: mounting these monstrous partitions... should I, or, in fact, do I *need* to give, as a mount option inode64? There will be a *lot* of files on this sucker.... What are the pros and cons of that? mark
