Re: Upgrading from ACS 4.2 to 4.7 (w/ CEPH)

[Nux! <nu...@li.nux.ro>]

Hello Indra,

I think the procedure is documented here (though not to 4.7, but that shouldn't make a difference)
http://cloudstack-release-notes.readthedocs.org/en/latest/upgrade/upgrade-4.2.html
cloudstack-awsapi has been obsoleted at some point, so before upgrading you might want to `rpm -e --nodeps cloudstack-awsapi`

Not sure if the CEPH component will add extra complexity. Perhaps other users can advise.

If you do not have a staging environment, then you should build one. I have such a thing within a single server with VMs (nested KVM virt), so you don't need to mess with multiple physical machines.

In terms of time, it's an operation that - if done manually on a small setup - takes less then an hour (assuming fast Internet), but I usually reserve the whole day/night for the unexpected.

Reversing your setup is not supported, but I guess it could be done, it would've been easier if you ran NFS with simple qcow2 files, though.
If you take a mysqldump of the management server, a backup of your system VMs disks (not sure how you backup/restore CEPH manually); then nothing is to stop you to "yum downgrade" and restore your SQL and sysVMs backups or just recreating the sysVMs/VRs with the old working template.

Personally I'd wait for 4.7.1 to be released which fixes some bugs.

Hi Lucian,

Good day to you, and thanks for your reply.

Yes, I built the ACS 4.2.0 from source last time and created the DEB
package for my Ubuntu. Nevertheless I checked the repository on
http://cloudstack.apt-get.eu/ubuntu/dists/precise/ and there seem to be the
package for 4.7 and 4.8, so will give it a try.

Would you recommend me to upgrade to 4.8.0 instead of 4.7.1? Any
differences in terms of bug fixings and new features between the two?

Looking forward to your reply, thank you.

Cheers.

[Nux! <nu...@li.nux.ro>]

Hello,

4.7.1 (and 4.8.0) are basically out, you can find the packages at http://cloudstack.apt-get.eu/ - the release notes and official announcement seem to be delayed a bit.
You can use the 4.6 systemvm with both of the releases.

Re Ubuntu I am sorry, no idea, I use CentOS 6 & 7.. You should be able to build the packages yourself though from source though, try it out.

Re: Upgrading from ACS 4.2 to 4.7 (w/ CEPH)

[Indra Pramana <in...@sg.or.id>]

Hi Lucian,

Thanks for your email reply.

We are using Ubuntu instead of CentOS so I guess the "rpm -e" will not be
applicable? My worry is that we are using Ubuntu 12.04 instead of the
Ubuntu 14.04 which is officially supported by ACS 4.7. Anyone has
successfully installed ACS 4.7 or upgraded to ACS 4.7 on Ubuntu 12.04
environment before?

Thanks for your recommendation for us to build a staging environment and
for us to wait for 4.7.1 to be released. Any information on when will ACS
version 4.7.1 will be officially released?

Looking forward to your reply, thank you.

Cheers.
