Mondoescue 3.2.1 is now available … with effort and pain !

2015/08/31

Believe it or not, it has been one of the most challenging version to produce ! And one which was really awaited by lots of people.

First all those of you who had problems restoring big files with 3.2.0 which had issues with that. Now that’s solved (was already with the beta previously).

Then those of you who had a RHEL 5 system. 3.2.0 wasn’t working, and 3.2.1 should be much better. Similarly for the people using RHEL 7. This is the real first version working for RHEL 7 available of MondoRescue. I’ve made most of my tests with a RHEL 7 VM in order to track all the errors which were remaining for that env (also some smaller but annoying ones). The root cause is that I had a customer wanting to move to that version for RHEL 7, and I wanted them to be happy with the result. Doesn’t mean they won’t encounter issues, despite what I did, but I’m much more comfortable to handle the cases in their support contract (Yes this is a paying customer).

And finally those of you who were trying to have a working environment for a UEFI based machine with RHEL 6. UEFI wasn’t working at all with 3.2.0 (and previous versions) even if EFI was working on Itanium systems. So this time I used a real system to make again lots of different tests, and solving again lots of issues linked to the support of UEFI, and now I’m happy with the result. The media made is recognized by the UEFI shell or the HP ProLiant guided boot menu. And a full backup / restore works also on it. So that other customer (an HP one, but not a paying one from a MondoRescue perspective… yet) should as well be happy and be able to use MondoRescue to perform its clones and installs correctly.

Could it be better ? Of course. RHEL 7 + UEFI are not yet friends. That will be for 3.2.2, as I want to keep my job ;-). Few bugs in trac have been addressed during these last 8 months, sorry for that. But a lot not mentioned there have been solved, and that was most of the work. And a lot of work has been put (commit hours are real !) into solving the customers needs and deliver that version on time. That’s probably why I hate time based releases, as it forces you to deliver (which is always good), but not with the serenity which should be part of an OpenSource development. Of course, that’s my fault ! I should have anticipated these requests (UEFI and RHEL 7 are there since a long time). But hey, this is still not my day job at HP. So I can only do my best as time permits. And I have a lot of other hobbies that I’ll be back to now so they can also know some progress. That’s also why I do not make more regular releases. But patches are always welcome.

Anyway, pain is over, a new version is here. Test it, report feedback, try to not break it too much, and remember to do regular backups whatever the tools you use.

Redfish 1.0 is now out and soon used by our projects

2015/08/20

Recently the DMTF announced that the Redfish standard had reached version 1.0, the first usable for production.

If you don’t know Redfish yet, and don’t want to read the full spec, I can summarize it very roughly as a cross-manufacturer RESTful API to configure Hardware systems and recover info from them. Pretty cool in fact as this was a missing brick for a full Open Source based multi-platform Software Defined Infrasctrucute.

Now remains for us to update our python-redfish with it, and start supporting more features now it’s stable. That the first step will allow Ironic, the bare metal component of OpenStack, to have Redfish support, which is IMHO a very highly desirable feature. Not for Liberty, hopefully the spec will be ready for M and code sufficiently developed to allow us to win a slot in the Summit !

Then it will also allow us to advance on the other project we’d like to promote: Alexandria, which is a clever (of course, I’m part of the design team ;-)) way to interface CMDBs (well the one who are themselves clever enough to have a parametrized data model such as iTop) and Hardware information providers such as Redfish.

Imagine that you rack a new Refish compliant server (HP ProLiant Gen9 are among the first to provide already a subset of it), cable power and management board, integrate some info on that machine in your CMDB (iLO credntial and IP address e.g.), and ask through Alexandria that the rest is filled by Redfish calls. And kept updated as time passes. Well, that’s exactly what we try to achieve, as this is one of the need we have to maintain our Solution Center CMDB up to date as easily as possible.

Lots of good ideas, but not enough code to show for now. Hopefully, we should be able to have an Alexandria demo with somple drivers ready for the upcoming OpenStack Summit… and be able to travel to exchange our views with other OpenStacker around all this.

Some personal news around OpenStack

2015/07/26

I’m trying to be more and more involved around OpenStack, as much as my time allows me of course.

So some recent news about that:

1/ I’m now a member of the Franch OpenStack Association Board and really proud to be listed alongside real long time contributors and advocates of the project.

2/ I’ve become an ATC during the Liberty cycle due to a modest contribution on Ironic. But it gives me the possibility to attend the Tokyo Summit !

3/ I’ve contributed to 3 proposals of talks for the upcoming Tokyo OpenStack Summit: the first one on the work we do to add support for Redfish in Ironic. The second is on a new project called Alexandria which we would like to see becoming an OpenStack project in the future and which is a CMDBaaS solution. Early stage but pretty neat ! And finally, we want to expose our view around a Software Defined Infrastructure with OpenStack.

If you think that any of these 3 presentations is worth listening during the upcoming Tokyo Summit, then vote for us before the 30th of July !!

I’d like to share other thoughts on the big tent and the community, but that will be for a next article.

Back to RMLL 5 years after !

2015/07/07

I like that event which is organized by different teams each year and gather thousands of enthusiasts during one week in one city to celebrate Open Source and Free Software.

This year, for the first time since 2010, I have no conflict attending it and also attending the Academy of sacred Music in Etampes, the week after, as I do since the first one.

So this year I’ll give a status of where we are with the MondoRescue project for my tenth anniversary of project leadership and after the last presentation I did 5 years ago.

And as you can’t be in the mood without docker, I’ll deliver a session on docker and project-builder to demonstrate its particular value IMHO in this domain of continuous packaging and also I’ll animate a Lab session on docker to help discover this tool and understand the challenge of containerizing an application such as owncloud. Come prepared with at least a Linux VM or better a Linux laptop to enjoy the tour :-) And start by downloading the Lab document based on Ubuntu 14.04 !

And don’t hesitate to come and talk of whatever topic I’d be able to cover such as AFUL, Mageia, OpenStack, Redfish and Ironic or the beauty of Jean Mouton’s music during the reign of François the first (not our current pope ;-))

Représentation HP à une table ronde du congrès Curie

2015/06/09

J’ai été invité à parler à la table ronde du congrès CURIE modérée par Eric Horlait

Son thème est: “CLA, un mode de coopération original pour animer une communauté du logiciel propriétaire” (sic). J’y aborderai pour ma part la manière dont HP gère son engagement auprès de communautés du logiciel libre et le gestion des contributions.

Je ne suis pas encore bien sûr de comment cela va s’articuler, mais si vous êtes curieux comme moi, rendez-vous demain à Pau pour le savoir !

Attending HP Helion MVP next week in Sunnyvale

2015/03/11

I’ve been recently awarded as an HP Helion MVP. And immediately after, invited to participate to the first HP Helion MVP Event in Sunnyvale on March 18th thru 20th, 2015. Looking at the mmebers and the presenters, that will be a great event, and I’m sure I’ll learn a lot through the discussions and presentations we’ll have.

On my way to the US, I’ll go through Seattle to meet with some HP colleagues arriving Monday night, and departing to Sunnyvale on Tuesday evening.

All that is a short trip, just before our big HP internal EMEA Event the week after, but I’m sure it will be worth the effort. And if you’re around as well, and want to talk about Open Source @HP, disaster recovery or cloning with MondoRescue, continuous packaging with Project-Builder.org or Helion OpenStack of course, feel free to drop me a mail so we can meet and talk.

MondoRescue 3.2.1 is definitively looking better but will for sure with your help !

2015/03/06

Since a couple of days, I’ve passed quite some time to deal with the various reports that were made on the mondo mailing list with regards to bugs found by users on version 3.2.0. Of course, as every .0 version, not everything was tested, and the help of the community is as usual key to find these cases left appart, and of course find bugs in them !

What has been fixed is available here:
http://trac.mondorescue.org/query?status=closed&group=resolution&milestone=3.2.1

The other BRs I’d like to address before releasing 3.2.1 are:

  • glibc detect an invalid pointer (#766)
  • Smartarray b120i closed drivers not working (#751)

and the older, but really annoying one:

  • Fail to Restore from External Hard Disk (#628)

While I think I can deal with the 2 first one pretty easily, the last one requires more time and will probably end up in 3.2.2 instead, as it’s difficult to delay more 3.2.1 now that the most annoying issues have been solved.

In the mean time, please test the beta of 3.2.1 at ftp://ftp.mondorescue.org/test/ (lots of distros available). That will clearly help me finalizing that version. Hopefully you’ll mostly report successes, but I really need your help to make it much better than 3.2.0.

With the latest devs made on mindi to support again correctly older distributions such as RHEL5 (which wasn’t working anymore in 3.2.0), I think I’ll also being able to make the promised 3.0.5 soon, for those wanting to avoid the risk of using a mondoarchive very different in code with lots of dynamically allocated memory. That will pretty surely be the last one in that serie. The focus is really now on the 3.2 branch.

Thanks for your continuous support on this project !

Merry Christmas, MondoRescue 3.2.0 is out !

2014/12/24

My previous post was to announce I wanted to publish that long overdue 3.2.0 version of MondoRescue beofre Christmas, so here we are !

I finally found the issue I had restoring RHEL7 with 3.2.0. This was due to a cumul of problems:

  • XFS labelling was broken. I fixed it by calling appropriately xfs_admin in label-partitions-as-necessary
  • RHEL7 uses a UUID for / in the grub2 configuration, which is not mentioned in /etc/fstab; so mindi wasn’t recreating that UUID correctly. So now mindi will store in the mountlist.txt the UUID of each partition, if no other LABEL or UUID was explicitely given in /etc/fstab in order to be able to use it at restore time, and label-partitions-as-necessary was also updated to take that in account

And I was with these modifications able to restore fully automatically a RHEL7 VM. So as I had alrady a working RHEL6 and Fedora 20 env, and as no big regression is expected on other supported distros (Mageia, SLES, OpenSuSE, Debian, Ubuntu mainly) I thought it was time to deliver it officially and give you a toy to play with for Christmas ! Am I not a nice guy ;-) ?

A lot as changed with regards to 3.0.4. If you want to have all the details, look at the Changelogs available in the trac announce, or read my previous posts about the 3.2 branch development, which started back in October 2013 (or even before in fact).

Is it the end of the 3.0 branch ? No. As I announced it earlier already, I want to at least publish a 3.0.5 with most mindi modifications backported in it (SVN already has such a branch in fact) in order for those of you who don’t like major updates, to stay with a more stable branch for some months, before jumping into 3.2.x. Because 3.2.x is the future, and most of my development time will happen here.

Hopefully that 3.0.5 branch will also work fine with systemd and /usr only based distros as the modifications to support that have all been done in mindi.

As for the 3.2.x branch, please report your findings ! I know I’m far from answering all mails, or answer all bug reports, but I do rad all of these, and as time permit, I try to make the code evolve (typically adding more perl functions) to have a more flexible way of incorporating your requests. Slower, but I have an installed base to maintain, I’m not like Fedora, which will always be followed, I need to keep my sysadmin as happy as possible with the state of the tool, while maintaing as much compatibility as I can with the previous versions.

But all that won’t happen before early January, as I’ll pass time with my kids and my wife to celebrate Christmas, an enjoy being together, which is now not as often as the previous years (yes kids grow up and move sometimes far from home :-), and that’s good !)

As I write packages are still being delivered to the master ftp server. Try it after the 25th !

MondoRescue 3.2.0: last beta before publishing

2014/12/07

I’m probably far from being a good project leader. The lack of time is one of the reason, but I think I could do better anyway, as I was particularly quiet these 2 last months. So I use that time, where I’m waiting before driving to the airport to give a status.

I was quiet, but still working on it as time permitted, and willing to solve the Fedora 18-20 support issues I had for a very long time now. And it seems that with the latest patches pushed this week, I’m good on that side. I’ve been able to do a full backup/restore of my Fedora 20 VM in automatic mode without issue ! That’s the first time, and was particularly happy that after 9 months of development around 3.2, I could achieve that. The other good news, is that it is still working fine for RHEL 6 e.g. as I also did a full cycle this week.

Ok, so life is nice. Well, as you know, nothing’s perfect ;-) So I still have an issue with RHEL 7. In fully automatic mode, eveything works fine, except that the restored VM doesn’t start due to an issue on the UUID in the initramfs.

I’ll test by recreating that initramfs after restore, and hopfully, dracut will do the job for me. But as I’ll be travelling in the US all next week, I thought it was good to publish a last beta before leaving, so that the community could also test and report what happens on other distros or on other configurations.

Note that very few other bugs have been fixed. I’m more interested for this first 3.2 version to have it work finally on all new systemd distros as much as I can, even if some features are still not fully working (see trac for details).

Compared to my last post on the subject, some points have been improved:

  • the network stack is now launched as long as a network backup has been done originally, even if you boot from the ISO image directly, and not through PXE. You may still choose from where to restore afterwards, but at least network is up
  • solve some /bin vs /usr/bin issues for pre-fedora 18 and systemd distros which were not working anymore (Cf: #741)
  • fix for a lack of keyboard discovery
  • fix some perl issues in some cases (Cf: #755)
  • force LV creation which on RHEL7 now asks a question in case something was already there before (Cf: #753)
  • Optimize modules list computation between mindi and restore init script and do not load modules list twice anymore
  • Force generation of hardlinks for busybox to avoid package build problem on some distro with inexistant links at build time (recent SLES)
  • Fix busybox 1.21.1 to support back old distributions such as RHEL3 and RHEL4 or SLES9 by avoiding usage of the struct tpacket_auxdata
  • Fix isolinux.bin and ldlinux.c32 locations for recent Debian distro

So maybe even more has been fixed than I considered initially in fact. Anyway, I’ll try to avoid to stay so long without publishing new versions to test. It’s a promise, but will be difficult to keep so don’t hold your breath !

I’d appreciate that you provide feedback on the MondRescue mailing list, create trac entries (even if I know there are already a lot that would need to be solved sooner than later).

The goal is to publish 3.2.0 final before Christmas, and to work on a hopefully final 3.0.5 version backporting some of the previously mentionned fixes coded in 3.2 for those of you who prefer to stay on that branch, which will be maintained a bit in parallel as long as 3.2 is not tested more. I think that you’ve been patient with me, so I also have to be patient myself before more users adopt the new stable branch.

Hopefully you’ll get a new blog article for the announce in less than a month !
