Thus using a SSD drive as cache for example. (at first sight fs-cache can only be used on the client side..) If the nfs server code itself kept its own cache, that would cause consistency problems between nfs clients and local users of the exported filesystem. So you want to solve the problem below the nfs level, in the vfs and/or filesystem. Making a filesystem use fs-cache requires modifying code of the filesystem. I don't know whether it would make sense to do that for a disk filesystem. There might be some benefit to putting the journal on an ssd; see e.g.: http://insights.oetiker.ch/linux/external-journal-on-ssd.html > And maybe not so related: can I do data de-duplication?

I believe people want btrfs to do deduplication some day. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
