Some interesting stuff for MondoRescue 3.0.4

2013/06/25

Well at least I hope so !!

It took me much more time than I expected, and made me sleep at insane hours (yes really !), but I think that the beta that I built today under ftp://ftp.mondorescue.org/test/ should be of interest for MondoRescue users.

Some new distros are now added to the list of the one I’m building for (Ubuntu 13.04, Debian 7.1, Mageia 3, Fedora 18, …) Usual job for me, but hey, still of interest for people wanting the latest one.

Speaking of latest Debian, MondoRescue should now work better on it thanks to the fixes around #699 (NFS and SSHFS support), softlink in LocateDeps which have now their target scanned, and some deblint issues removed, including right test binaries placement, and man pages for perl scripts. I have someone working now with me on the re-integration of MondoRescue into Debian, so this version should help him reducing the diffs with his tree, and allow for the next steps (on the packaging itself) to go forward for our goal.

Of course, some annoying bugs reported have been fixed. At least we all hope so ;-)

  • grub2 support in #686 by adding grub.conf, grub.cfg and modified device.map.lst to device.map (Thanks to Victor Gattegno),
  • Fix support for OBDR tapes connected to SCSI cards and addition of an obdr modsboot parameter if some additional drivers should be removed,
  • an particularly nasty bug (there since rev 1 !) on SLES 11 SP2 by removing a dd in mindi which was filling the target dir,
  • the full management of scratch and tmp dir has been rewritten, hopefully for a better implementation now and a full resolution of #640,
  • the removal of the notion of number of media (limited to 50 abusively). Cf: #706
  • the addition of a -F option which allows mondoarchive to fail at first interaction. Cf: #702
  • sparse file support by adding a CLI parameter -M to modify the biggie file size limit, by default 64 MB, and by using st_blocks instead of st_size. Cf: #700
  • Fix #679 again and #685 by reducing the list of possible kernels (Thanks to Victor Gattegno and Didier Diaz)
  • Fix #696 for VGs not having a ‘-‘ in their name such as multipath aliases
  • Fix #703 by removing the errctl field used in star and log all star msgs into mondorestore.log. star is now considered production level as afio

And some improvements in the doc such as:

  • Adds more info in mindi log file (df -i, df -a, grub/lilo conf files, fdisk -l)
  • Add an example to use a fixed IP configuration at boot time through mindi.conf
  • Be more precise in messages displayed at restore time when a non-rewinding device should be used
  • Document the new -F and -M options
  • Precise the usage conditions of the exclude option (differences between device vs directory exclusion)
  • Indicate the other new tools than mkinitrd to help rebuilding the boot env (Thanks to Philippe Lefevre)
  • Precising compression rates on GUI button to ease choice (0 is no compression)

Some ongoing efforts at this point would require your help, dear reader to give appropriate feedback to see if we are making progresses:

  • Fix #628 by avoiding to erase choices done for variable bkpinfo->isodir and g_isodir_device in iso_fiddly_bits later in the code
  • Fix #208 by adding cifs support with first modifications to add cifs support as an external FS

So please help us by downloading this beta, which is IMO near from being the next stable and report wheher it’s working fine for you, or whether it’s working really fine for you ;-)

I have to say that most of these bugs wouldn’t have been fixed without the work I’ve done for HP’s customers recently, who are using extensively the tool, and were needing these fixes to have it fully working in their environment (RHEL and SLES in multiple versions on HP ProLiant servers). Pending their feedback on this version, I’ll declare it stable if they give me the green light, which should arrive soon now.

MondoRescue 3.0.3 is finally out

2013/03/17

I know. It’s been a long process. And I’m not even fully satisfied with the results, as we do have unresolved bugs in this version. But as it also fixes some critical others that were expecting for a long time (3+ months), I didn’t want to delay more the release of this version.

So here it is. mondo 3.0.3, mindi 2.1.4 and mindi-busybox 1.18.5-3 are now availble from the master ftp server. And as given in the announce, most of the distributions (nearly 100 of them) also have packages ready for use. Once more couldn’t do it without project-builder.org :-)

The detailed change logs are available for mindi, mindi-busybox and mondo.

Among the main fixes brought by this version, a much better support of SLES 10, SLES 11 SP1, SLES11 SP2, especially for LVM and device exclusion, grub, keyboard.

I also received very, very valuable contributions from users, which helps producing a better version of course, and reduce the time of the resolution of the problem in the upstream version. Thanks again for helping ! Including on some very old bugs. And Victor being one of the most prolific.

There are even some new features such as the support of swaplabel or the inclusion of all tools part of minimal.conf now in the first boot part.

As said earlier, some bugs ar not fixed yet. I passed most of the week trying to fix the automatic mode where CTRL-ALT-DEL doesn’t work. I added support in 3.0.3 of an inittab file, but whatever the conf I use fo now, it doesn’t trigger a reboot when using the magic key or sending it from the KVM monitor. So be warned and use with care. I’ll report on the busybox ML as I still have the issue with 1.20.2, and try to get help from this community. Could well trigger the release of a new mindi-busybox (and maybe mindi) soon after this one.

In the serie of un-fixed bugs for lack of time for this time are some that a user reported as more important to fix soon:

  • Ticket #628: 3.0.2-1 Fail to Restore from External Hard Disk – This is a very big issue here.
  • Ticket #641: Specifying the Same Backup to NFS via CLI=Success via GUI=Fail – Although it is possible to work around this problem it is preventing the creation of exceptional backups by users with little knowledge of Mondo. A fix will be most welcome and will present a more appropriate impression of Mondo.
  • Ticket #640: mondo.tmp.xxxxx & mondo.scratch.xxxxx Issues – This is not a critical issue. A fix will help with backup management and housekeeping tasks.

I globally agree these are also important to fix (even if less than Ticket 627). I also think we need to work on Ticket 656 as well. I’d like to get your comments as well in order to prioritize the fixes in the next version, as I can’t work full time on MondoRescue, so need to choose where to put my efforts.

Finally time to publish pb 0.12.2

2013/03/01

As you can see with the few messages I had time to post on this blog, the end of 2012 start of 2013 has been pretty busy, and I’m late in delivering the 2 projects I’m leading. So this week, I decided it was time to make a 0.12.2 version of pb, and make it available. Was asked by my colleagues of FOSSology, specially to add Fedora 18 support, so I also build my VMs to make packages on this distro.

BTW, a bit of ranting for Fedora once more: no perl by default :-(, and no ifconfig nor route command either which is breaking MondoRescue of course, and I guess tons of other software around. These guys don’t care about past, but don’t provide compatibility tools either !! So I’ll have to make new patches, just to do the same as what was done, but with another command again. Not to speak of systemd which I still have issues to deal with :-( That doesn’t make stuff go faster !

Anyway, the version is now out, no official bugs fixed, but a lot of small stuff here and there which were desrving a release. No time to test Fedora 17/18 VE yet, so you’ll have to do that yourself if you want. I also had a look at virsh usage in combination with pb, and it’s again not as easy as it could seem to be. Especially port redirection I’m easily using by launching qemu-kvm manually with the -redir or hostfwd option doesn’t seem to be possible with the user mode network through virsh (neither manager nor CLI). Will have to post on their ML to see how they do that, if they can !

And MondoRescue has been very late. I really need to publish a verion, but I still have some blocking bugs I really would like to get rid of: CTRL+ALT+DEL not working anymore during restore, some LVM issues on RHEL, some grub issues on SLES… Hopefully at the end of next week I’ll have made progresses.

Of course patches are much easy to integrate, but I receive more bug reports than them ;-)

And also back to preparing the HP internal TES event, Solutions Linux confs, submitting to LinuxCon, working on an FLOSS ITIL stack, learning more OpenStack, looking at Intel’s TXT…. so many things I’d like to do or learn and will never have time to ! Maybe at least I’ll talk about that another time.

Availability of the beta of MondoRescue 3.0.3 (and mindi 2.1.4)

2012/11/21

We have had a long work on this version to fix some issues reported by a customer on SLES 11 SP2 particularly, which will benefit all MondoRescue users. The support of that last version of SLES is now fully working, and it allowed us to fix issues around LVM, /dev/dm-* devices and grub boot loader re-installation. A lot of other bugs have been fixed during this version (some 23), and I really encourage you to test it and report your findings on our mailing-list.

Before the final publication, I’d like to fix the issues encountered by Fedora 17 users, but I’ve not neen able to reproduce it correctly on my side up to now, and I stil l have to work on the latest log files reported to me in order to understand what is creating the issue some users are seeing.

But if no blocking point is found before end of week, and if my tests are successful, I think we’ll have a good 3.0.3/2.1.4 couple that I’d like to push as stable. Fedora fixes could then be done in a later mindi version (as this is what is mainly creating a problem now).

Thanks for your patches, support and now tests !

New Mondorescue 3.0.2 beta version available

2012/04/25

This version will fix again some problem met by customers or community users. Among these, as detailed earlier, the crash at restore time that was affecting users of MD software raid volumes, and the fact that we are now supporting UUID for their designation such as on RHEL 6.

Also for RHEL 5 users, there was an error on “no space left on device” at restore time, due to a modification in the way we are including more tools in the initrd, leading to the inclusion of the MAKEDEV program which was creating issue on device creation leading to that error message. It turns out this is also triggered by the busybox shell, so as we need anyway bash in the initrd, we will now use bash by default as the shell to launch all our scripts at restore time.

Mindi log files included in mondoarchive.log will also now be the expected one, not the one from an intermediate run.

2 contributors also provided fixes for issues: one for correct keyboard support by SLES by Victor Gattegno (who also helped around other bug fixes in this version), another one around the support of multiple PVs by bzium.

Even if 19 bugs were closed, I still have 2 issues that I’d like to fix before releasing 3.0.2: one around SLES grub install issue, and one around duplicate hpsa driver. And there are some others that may find their way in it. But that will be difficult, as I have a training in UK from the 2nd of May to the 4th of May, so I’ll publish the new version before in order to have it available at the training time !

So please test the beta version I made available at ftp://ftp.mondorescue.org/test and let me know if you find it stable for your case, and what other remaining issues you’d like me to work on next.
