Re: ceph-deploy won't install luminous (but Jewel instead)

[David Turner <drakonstein@xxxxxxxxx>]

You mean documentation like `ceph-deploy --help` or `man ceph-deploy` or the [1] online documentation? Spoiler, they all document and explain what `--release` does. I do agree that the [2] documentation talking about deploying a luminous cluster should mention it if jewel was left the default installation on purpose.  I'm guessing that was an oversight as Luminous has been considered stable since 12.2.0. It will likely be fixed now that it's brought up but the page talking about deploying would do well to have a note about being able to choose the release you want for simplicity.

As a side note, it is possible for any one of us to make change requests to the documentation as this is an open source project. I have a goal to be more proactive with taking care of goofs, mistakes, and vague parts of the documentation as I find them. I'll try to do a write-up for others to easily get involved in this as well.

Ah!
So you think this is done by design?

However that command is very very very usefull.
Please add that to documentation.
Next time it will save me 2/3 hours.

Hi Max,

I had the same issue (under Ubuntu 16.04) but I have read the ceph-deploy 2.0.0 source code and saw a "—-release" flag for the install subcommand. You can found the flag with the following command: ceph-deploy install --help

It looks like the culprit part of ceph-deploy can be found around line 20 of /usr/lib/python2.7/dist-packages/ceph_deploy/install.py:

…

    14 def sanitize_args(args):

    15    """

    16    args may need a bunch of logic to set proper defaults that argparse is

    17    not well suited for.

    18    """

    19    if args.release is None:

    20        args.release = 'jewel'

    21        args.default_release = True

    22

    23    # XXX This whole dance is because --stable is getting deprecated

    24    if args.stable is not None:

    25        LOG.warning('the --stable flag is deprecated, use --release instead')

    26        args.release = args.stable

    27    # XXX Tango ends here.

    28

    29    return args

…

Which means we now have to specify "—-release luminous" when we want to install a luminous cluster, at least until luminous is considered stable and the ceph-deploy tool is changed. 

I think it may be a Kernel version consideration: not all distro have the needed minimum version of the kernel (and features) for a full use of luminous.

Didn't check at time.

I deployed everything from VM standalone.
The VM was just build up with fresh new centOS7.4 using minimal installation ISO1708.
It's a completly new/fresh/empty system.
Then I run:

yum update -y
yum install wget zip unzip vim pciutils -y
yum install epel-release -y
yum update -y
yum install ceph-deploy -y
yum install yum-plugin-priorities -y

it installed:

Feb 27 19:24:47 Installed: ceph-deploy-1.5.37-0.noarch

-> install ceph with ceph-deploy on 3 nodes.

As a result I get Jewel.

Then... I purge everything from all the 3 nodes
yum update again on ceph deployer node and get:

Feb 27 20:33:20 Updated: ceph-deploy-2.0.0-0.noarch

... then I tried to reinstall over and over but I always get Jewel.
I tryed to install after removed .ceph file config in my homedir.
I tryed to install after change default repo to repo-luminous
... got always Jewel.

Only force the release in the ceph-deploy command allow me to install luminous.

Probably yum-plugin-priorities should not be installed after ceph-deploy even if I didn't run still any command.
But what is so strange is that purge and reinstall everything will always reinstall Jewel.
It seems that some lock file has been write somewhere to use Jewel.

This worked.

However somebody should investigate why default is still jewel on Centos 7.4

Asunto: ceph-deploy won't install luminous (but Jewel instead)

This is the 5th time that I install and after purge the installation.
Ceph Deploy is alway install JEWEL instead of Luminous.

No way.... even if I force the repo from default to luminous:

https://download.ceph.com/rpm-luminous/el7/noarch

It still install Jewel.... it's stuck.

I've already checked if I had installed yum-plugin-priorities, and I did it.
Everything is exaclty as the documentation request.
But still I get always Jewel and not Luminous.
