We have started looking into encryption support in ceph-volume, and one of the unclear paths is if we really want to support both "plain" and "LUKS". According to the cryptsetup docs [0] : (LUKS) is now the preferred way to set up disk encryption with dm-crypt using the cryptsetup utility ceph-disk supports both plain and LUKS, but moving forward, I was interested in understanding if anyone is really expecting the "plain" type to be a choice? The legacy support will mean that ceph-volume will have to deal with "plain", but moving forward it might be easier if we are supporting a single type of encryption with LUKS. -- 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
