These applications sure seem like a better fit for ordinary snapshots. It looks like with the cloneset, there's a whole superfluous copy of the filesystem, whereas with a snapshot, you have to have storage space and I/O time only for data that changes after the snapshot. I'm sure I could dream up an application for this -- maybe you want that second copy as a backup or it gives you additional data transfer capacity. I just don't see the panacea so far. -- Bryan Henderson IBM Almaden Research Center San Jose CA Filesystems - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
