[gentoo-user] Updating our live servers. I'm scared!

[gentoo-user] Updating our live servers. I'm scared!

[Nick Khamis]

Hello Everyone,

Just got a ticket assigned to me where we need to update our production servers.

uname -a
Linux noun 3.4.9-gentoo #2 SMP Sat Oct 13 09:35:07 EDT 2012 x86_64
Intel(R) Xeon(TM) CPU 3.60GHz GenuineIntel GNU/Linux

eselect
[18]  hardened/linux/amd64 *

I don't think they have been updated since the initial install and
wanted to get a little feedback on some safe practices and methods
that should be performed before and while doing so.

Thanks in Advance,

Nick.

Personally, I would recommend pulling an rsync (databases and such might
cause a hiccup with that) of one of them to a nonessential system and
testing updating there, building packages (assuming matching use flags,
etc, across your systems), documenting the pitfalls you run into as you go.
After you're up to date there, run through and test it again from a base
copy, then test the actual services to ensure changes to them don't hose
your environment's configuration, and once that's good, it then depends
entirely on what failover, or downtime allowances you have available. If
you have no failover to rely on, and can't afford enough downtime to update
the system in place from the packages you've built, clone each off, update,
then migrate the changes that've occured in the time between... time
consuming, and requires a lot of care, but doable.

[Nick Khamis]

So basically rsync configs and databases first? When issuing updates
to world and so no. What is the safest process/order to sync portage,
and update world? I have seen a number of flags various example use,
and was wondering if someone can give me the safest and equally
effective commands with flags included.

Thanks again,

Nick.

This isn't that old, you'll be fine. First run an emerge --sync to
update the tree. Then list everything it wants to upgrade:

  emerge -puDN1 world

Once you have that list, go through a few at a time, updating
non-essential packages. For example,

  emerge -u1 timezone-data man-pages ...

Every once in a while, run a revdep-rebuild. If you have service
monitoring (e.g. Nagios), great, it'll alert you if something breaks. If
not, you'll have to test the services yourself every few packages. And
don't forget to open a counter-ticket for someone to implement a
monitoring solution, already.

After a while, only important packages (apache, mysql, postfix...) will
be left. Do those one at a time, and restart the services afterwards.
Read the release notes first. Run revdep-rebuild. Check that the
services work.

Finally, you'll be left with the guaranteed-to-break updates like grub2
(50/50) and udev (100% you're fucked prepare for downtime). Grub2 can of
course be skipped until the hardware dies. Best of luck to you with udev =)

Re: [gentoo-user] Updating our live servers. I'm scared!

[Nick Khamis]

Hahahah udev hell!! I did go through that updating from 2.6 to 3.4.
That was quite an experience!!!! But for kernel 3.* has udev not been
phased out in our gentoo boxes? Will have to double check when I get
back behind a console.

I'm afraid not! Once you sync, you can do,

  eselect news read 23

to see the news item that was posted about it (title:
2013-01-23-udev-upgrade). Even that doesn't contain all of the
information.. some of it is spread throughout bugs and across mailing
list discussions.

Oh and they decided to rename your NICs to owiu23awds89, which stands
for,
actually-nobody-knows-welcome24-to16-hell9-slot12-moon-phase-36-hey-if-you-enjoyed-this-give-systemd-a-try,
or something like that. It's all explained very poorly in the cited links.

I'm being a bit dramatic. I would plan on spending ~4 hours researching,
planning, and documenting the udev upgrade. Maybe an hour to execute it
in the middle of the night, physically present. You can expect around 15
minutes downtime if all goes well.

The rest of the updates you can do at your leisure, although the
critical services should be restarted and checked during off-hours.

Hmm.. this is probably /someone's/ bug. Nevertheless, all you have to do
to fix it us update portage to the current stable version, which
supports EAPI5. Can you switch to another profile temporarily and get
portage updated?

I guess this is related to the recent profile upgrade (as of 2013-02-10).
In my
$ eselect news list
I get the last news item related to this upgrade.
As it states,
"Everyone should upgrade as soon as possible (but please make sure 
sys-apps/portage is updated to current stable *before* you switch 
profile)..... this formally requires a new profile tree with EAPI=5."

So, read the news item, emerge portage, then
# eselect profile
and you're done.

I switched to the default profile from hardened:

 eselect profile list
Available profile symlink targets:
  [1]   default/linux/x86/13.0 *

env-update
!!! Unable to parse profile: '/etc/portage/make.profile'
!!! ParseError: Profile contains unsupported EAPI '5':
'/usr/portage/profiles/default/linux/x86/13.0/eapi'
>>> Regenerating /etc/ld.so.cache...

And still can't update portage.

But we never changed our profile? Always running hardened server.

[Nick Khamis]

As mentioned earlier a temporary change of profile got me on my way

eselect profile set 0
env-update
eselect profile set 7

Moving forward... Thanks guys.

Just a thought.  Have you thought about switching to eudev?  That would
solve some udev issues.  Since you are running a hardened profile and
servers, may not be a option tho.

I just wanted to mention it in case its existence had slipped your
mind.  I know when the time came, I switched from udev to eudev and it
has worked fine for my desktop.  I plug in cameras, USB sticks, printers
and other goodies which is likely something you don't do on a server. 
After reading about all the troubles others have had, I'm glad I
switched.  My network still has the same name and all too.  Still
crossing fingers tho. 

I just wasn't sure how compatible eudev would be with a hardened profile
is all. 

Best of luck with the upgrade tho.

eudev - is it a viable *long-term* option? - WAS: Re: [gentoo-user] Updating our live servers. I'm scared!

I'm curious...

Is eudev still being 'maintained'? Does it still have any advantages 
over the new udev?

I'm mostly concerned about getting so far behind that I end up in an 
untenable situation... ie, eudev dies in 1+ years, and the changes 
between now and then make it virtually to update to whatever is the new 
way...

Re: eudev - is it a viable *long-term* option? - WAS: Re: [gentoo-user] Updating our live servers. I'm scared!

[Tanstaafl]

I should have added that this is for a server (not hardened), so I don't 
care about hot plug this or that, I just care about stability and 
reliability with respect to updates not breaking booting capability...

As far as I know, it is actively maintained.  Do I see the people
banging hammers, no.  lol  I did have a update on eudev tho:

     Sun Feb 10 20:07:23 2013 >>> sys-fs/eudev-1_beta2-r2
       merge time: 55 seconds.

This is from the changelog for eudev:

  Update eudev ebuilds to support ROOT properly


It seems the latest change was March 10 which was not long ago.  As I
mentioned earlier, I have plugged in USB sticks, cameras, printers and
such pretty regular.  The eudev fork has worked fine for me.  Servers
seem to worry less about *new stuff* since they usually run with what
they have at boot time anyway.  Heck, mdev may would work fine for you
too. 

It seems based on reading the -dev list that udev is about to introduce
some more changes.  I'm hoping those don't affect me either.   I just
noticed that someone else on this list has ran into the news message for
it too and has questions already.

I do remember the conversation about mdev... probably should have paid 
closer attention.

Is the conversion fairly simple? Is there an updated how-to, 
specifically for older udev (171)?

Thanks...

Try this:

That was originally done by Walter and he does subscribe to this list,
saw a post not to long ago.  If you run into issues, I'm pretty sure he
will help if he can.
