This is because filesystems impose limits on name size and we do store xattrs in the filesystem in the default configuration with most releases of Ceph (they overflow into leveldb if there are too many). If that's really going to be a problem for you...I don't know what to say, sorry. These are close to limits you should have been following already fi you want your stuff to work on e.g. ext4. :) -Greg -- 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
