It doesn't matter, I think filestore_xattr_use_omap is a 'noop' and not used in the Hammer.

Now he can't remember why. He thinks it may be a holdover from our first Ceph cluster (running dumpling on ext4, iirc). In the newly built cluster, we are using XFS with 2048 byte inodes, running Ceph 0.94.2. It currently has production data in it. >From my reading of other threads, it looks like this is probably not something >you want set to true (at least on XFS), due to performance implications. Is >this something you can change on a running cluster? Is it worth the hassle?
