ceph-volume has always used LVM behind the scenes, this is the
default, and there is no other support for creating new OSDs that is
not LVM-based.

If you don't want LVM, you can continue to use ceph-disk. There is
room for developing non-LVM support, but we haven't seen any issues
with LVM so far, so there is no
incentive to try a different route at this point.

I think this is regression. What if I don't need LV?

Not sure I follow, ceph-volume has two ways of provisioning OSDs, one
is by taking over currently deployed OSDs (ceph-disk or manual)
and the other one is with LVM.

ceph-volume accepts a bare block device as input, but it will create
an LV behind the scenes

ceph-disk should be considered as "frozen" and deprecated for Mimic,
in favor of ceph-volume.


ceph-volume will continue to support bare block device, i.e. without 
lvm'ish stuff?

I worry about the way we poke at devices for setups (blkid, lsblk,
/proc/mounts, etc...)

The creation of the OSD (aside from devices) is straightforward

We can't delay this for ~8 months because it will obfuscate what
breakage we will find on our end by ripping it up (teuthology suites,
etc...)

I've already started working on it, and we should be looking at 2 to 3
weeks from today.

There is no "scenario" because ceph-volume scans the existing OSD and
whatever that gives us we work with it:

* filestore with collocated/separate journals
* bluestore in any kind of deployment (with wal, with db, with db and
wal, with main only)

multiply that with *both* ceph-disk's way of encrypting.

In short: we support them all. No special command or flag needed.

Re: [ceph-users] ceph-disk is getting removed from master

[Vasu Kulkarni]

Alfredo,

Do we have the migration docs link from ceph-disk deployment to
ceph-volume? the current docs as i see lacks scenario migration, maybe
there is another link ?
http://docs.ceph.com/docs/master/ceph-volume/simple/#ceph-volume-simple

If it doesn't exist can we document, how a) ceph-disk with filestore
(with/without) journal can migrate to ceph-volume  and b)
ceph-disk/bluestore with wal/db on same/different partitions.

Regards
Vasu

Yup, I'm aware of my "trouble"/commitment.

Now that you have riped out most/all of the partitioning stuff there
should not much that one would need to do in ceph-volume other than
accept the filestore directories to format the MON/OSD stuff in.

IFF I could find the time to dive into ceph-volume. :(
ATM I'm having a hard time keeping up with the changes as it is.

I'd appreciate if you could delay yanking ceph-disk until we are close
to the nautilus release. At which point feel free to use the axe.

[ceph-users] ceph-disk is getting removed from master

[Alfredo Deza]

Now that Mimic is fully branched out from master, ceph-disk is going
to be removed from master so that it is no longer available for the N
release (pull request to follow)

ceph-disk should be considered as "frozen" and deprecated for Mimic,
in favor of ceph-volume.

This means that if you are relying on ceph-disk *at all*, you should
plan on migrating to ceph-volume for Mimic, and should expect breakage
if using/testing it in master.

Please refer to the guide to migrate away from ceph-disk [0]

Willem, we don't have a way of directly supporting FreeBSD, I've
suggested that a plugin would be a good way to consume ceph-volume
with whatever FreeBSD needs, alternatively forking ceph-disk could be
another option?
