Re: cephadm and disk partitions

Hi Robert!

Thanks for answering my question. I take it you're working a lot with Ceph these days! On my pre-octopus clusters I did use LVM backed by partitions, but I always kind of wondered if it was a good practice or not as it added an additional layer and obscures the underlying disk topology. Then on this new octopus cluster I wanted to use the new cephadm approach for management and it seems to steer you away from using partitions or LVM directly, thus my question. I don't really have the option to not use partitions in this particular instance. I was merely curious if there was a particular reason that cephadm doesn't consider partitions (or LVM) as being "available" devices. All the storage in this cluster is the same so no need to split metadata on to faster storage in my instance. Anyway, it's good to hear from you. Hope you and your family are doing well.

Thanks,
Jason
