Are these xattrs being > stored in a key-value store or in XFS file system? They are stored in XFS, until there are more than a handful, after which point they get stored in leveldb.

They are meant to be small and few. sage -- 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
