Upgrading iocage jails from FreeBSD 10.3 to 11.0 (major upgrade)

/ dsdickinson / Leave a comment

Iocage makes upgrading jails quite simple. It can be a little more involved than the host upgrade but not by much.

First on the host server we need to fetch the right version of FreeBSD for iocage to use. This will create the iocage zfs file system structures for upgrading to and building 11.0 jails.

$ sudo iocage fetch 11.0-RELEASE

$ zfs list

Here we have an issue with the old pkg binary which is linking to a version of libssl that no longer exists. To fix this we need to reinstall the pkg binary.

$ pkg-static install -f pkg

Upgrading from FreeBSD 10.3 to 11.0 (major upgrade)

/ dsdickinson / Leave a comment

Performing a major upgrade isn’t much different from doing a minor upgrade as far as ease goes. However more can go wrong. Here we’ll discuss the basic commands to get through it.

First we want to get to the latest and greatest minor version patch level of FreeBSD.

$ sudo freebsd-update fetch
Looking up update.FreeBSD.org mirrors... 4 mirrors found.
Fetching metadata signature for 10.3-RELEASE from update6.freebsd.org... done.
Fetching metadata index... done.
Fetching 2 metadata patches.. done.
Applying metadata patches... done.
Inspecting system... done.
Preparing to download files... done.
Fetching 324 patches.....10....20....30. done.
Applying patches... done.
Fetching 40 files... done.

The following files are affected by updates, but no changes have
been downloaded because the files have been modified locally:
/etc/mail/freebsd.cf
/etc/mail/freebsd.submit.cf
/etc/mail/sendmail.cf
...

The following files will be removed as part of updating to 10.3-RELEASE-p15:
/usr/share/zoneinfo/America/Santa_Isabel
/usr/share/zoneinfo/Asia/Rangoon

The following files will be added as part of updating to 10.3-RELEASE-p15:
/usr/share/zoneinfo/Asia/Barnaul
/usr/share/zoneinfo/Asia/Famagusta
/usr/share/zoneinfo/Asia/Tomsk
/usr/share/zoneinfo/Asia/Yangon
...

The following files will be updated as part of updating to 10.3-RELEASE-p15:
/bin/freebsd-version
/lib/libc.so.7
/rescue/[
/rescue/atmconfig
/rescue/badsect
...

$ sudo freebsd-update install
Installing updates... done.

Now let’s do the major upgrade:

$ sudo freebsd-update upgrade -r 11.0-RELEASE
Looking up update.FreeBSD.org mirrors... 4 mirrors found.
Fetching metadata signature for 10.3-RELEASE from update3.freebsd.org... done.
Fetching metadata index... done.
Fetching 1 metadata patches. done.
Applying metadata patches... done.
Inspecting system... done.

The following components of FreeBSD seem to be installed:
kernel/generic src/src world/base world/games world/lib32

The following components of FreeBSD do not seem to be installed:
world/doc

Does this look reasonable (y/n)? y

Fetching metadata signature for 11.0-RELEASE from update3.freebsd.org... done.
Fetching metadata index... done.
Fetching 1 metadata patches. done.
Applying metadata patches... done.
Fetching 1 metadata files... done.
Inspecting system... done.
Fetching files from 10.3-RELEASE for merging... done.
Preparing to download files... done.
Fetching 45032 patches.....10....20....30....40....50. done.
Applying patches... done.
Fetching 12099 files... done.
Attempting to automatically merge changes in files... done.

The following file could not be merged automatically: /etc/defaults/rc.conf
Press Enter to edit this file in /usr/bin/vi and resolve the conflicts
manually...

At this point you’ll be placed into various files that have merge conflicts. They will need to be resolved. In each file you will see the markers that designate the old files content vs the new files content such as:

<<<<<<< current version
# $FreeBSD: release/10.3.0/etc/syslog.conf 194005 2014-06-11 15:07:02Z avg $
=======
# $FreeBSD: release/11.0.0/etc/syslog.conf 238473 2016-07-15 10:55:43Z brueffer $
>>>>>>> 11.0-RELEASE

Basically you will choose which content wins (typically the new content) by removing the markers and the old content. So in this example you would end up with:

# $FreeBSD: release/11.0.0/etc/syslog.conf 238473 2016-07-15 10:55:43Z brueffer $

Now we will continue on. Next you will be asked if various merges that did not have conflicts look reasonable.

The following changes, which occurred between FreeBSD 10.3-RELEASE and
FreeBSD 11.0-RELEASE have been merged into /etc/defaults/periodic.conf:
Does this look reasonable (y/n)?

The following files are affected by updates, but no changes have
been downloaded because the files have been modified locally:
/.cshrc
/.profile
/root/.cshrc
/root/.k5login
/root/.login
/root/.profile
...
To install the downloaded upgrades, run "/usr/sbin/freebsd-update install".

$ sudo freebsd-update install
$ sudo shutdown -r now

$ hostver
FreeBSD 10.3 RELEASE-p15

$ sudo freebsd-update install
Installing updates...

Completing this upgrade requires removing old shared object files.
Please rebuild all installed 3rd party software (e.g., programs
installed from the ports tree) and then run "/usr/sbin/freebsd-update install"
again to finish installing updates.

$ hostver
FreeBSD 11.0 RELEASE-p6

$ uname -r
11.0-RELEASE-p2

$ sudo shutdown -r now

Now lets upgrade the packages on the system.

Finally we’ll upgrade any perl modules on the system from cpan.

$ sudo cpan-outdated | sudo cpanm

So, to recap the commands are as follows and in this order:

$ sudo freebsd-update fetch
$ sudo freebsd-update install
$ sudo freebsd-update upgrade -r 11.0-RELEASE
$ sudo freebsd-update install
$ sudo shutdown -r now
$ sudo freebsd-update install
$ sudo pkg upgrade
$ sudo cpan-outdated | sudo cpanm

Display “real” FreeBSD version

Typically when you want to find the current version of FreeBSD you type the following:

$ uname -r
10.3-RELEASE-p4

That’s great but it doesn’t tell the full story. If updates were made that do not affect the kernel, than it will not be reflected here. For instance, if the system had been upgraded to patch 12 I would not know that from looking at this. It makes it look like its only been updated to patch 4. Enter the “/usr/src/sys/conf/newvers.sh” file. This file gives a more clear picture of the system’s current state of affairs. I wrote a quick script that grabs the relevant info from this file and displays it similarly to the uname output.

#!/usr/local/bin/perl

use strict;
use warnings;

my $file = "/usr/src/sys/conf/newvers.sh";
my $cnt = 0;
my ($type, $rev, $branch);

open (FILE, "$file") or die "File $file does not exist!";
while (<FILE>) {
 chomp ($_);
     if ($_ =~ /^TYPE="(.*)?"/) {
         $type = $1;
         $cnt++;
     }
    if ($_ =~ /^REVISION="(.*)?"/ && $cnt == 1) {
         $rev = $1;
         $cnt++;
     }
     if ($_ =~ /^BRANCH="(.*)?"/ && $cnt == 2) {
         $branch = $1;
     }
}
close (FILE);

print "$type $rev $branch\n";

I put this script in /usr/local/sbin/hostver on all the systems I administer.

$ hostver
FreeBSD 10.3 RELEASE-p12

Now I always know the current patch level of the system. There are other ways to get this info (freebsd-version) but this works fine for me.
