Please help me out . That's on an ext4 filesystem, I guess? In your ceph.conf, say [global] filestore_xattr_use_omap = true and probably you'll need to also remount that partition with -o user_xattr Better ext4 support is tracked in http://tracker.newdream.net/issues/3138 -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
