Hi,

Is there anyone currently using this in production?
How much ram is needed when you fsck with a many files on such a volume?
Dave Chinner reported 5.5g or so is needed for ~43TB with no inodes.
Any recent issues/bugs one needs to be aware of?
Is inode64 recommended on a 64-bit system?
Any specific 64-bit tweaks/etc for a large 43TiB FS?

Justin.
