back to article Upgrading what might be the world's oldest running Linux install

There are some complexities involved in upgrading what the Reg FOSS desk suspects may be the world's oldest running Linux installation: an OS install dating back to 1993. The machine called chiark.greenend.org.uk appears to be a relatively ordinary webserver, hosting a bunch of home pages, a few mailing lists, usenet groups …

    So the next upgrade ought really to move across to Devuan. That would be an interesting exercise indeed, at many levels.

    What's remarkable about Chiark is that it was originally installed with Debian Linux 0.93R5 in 1993, and the same installation of the OS is now running Debian 11 "Bullseye", the x86-64 version, freshly upgraded from an x86-32 installation of Debian 8 "Jessie".

    So it started life on 0.93 then got upgraded and virtualised (I assume over many iterations) to version 8 from where it has been upgraded to version 11.

    I had initially thought it was a direct impressive upgrade from 0.93 to 11 on the original tin!!

    Until a few months back I had preference and other system files on my Mac from my original lcii from 1992, I clearly no longer have need for Macdraw, Claris works, HyperCard or Chuck Yeager's Air Combat files!

      Re: Triggers Broom

      The linked account (well worth the read, BTW) doesn't suggest that it's virtualised but it does say "Obviously it’s had several new hardware platforms too." so, yes, definitely Trigger's broom.

      Yes, this is, AFAICT, on the "original tin" and *not* virtualised.

      > I had initially thought it was a direct impressive upgrade from 0.93 to 11 on the original tin!!

      Your original thought was correct. It is not _direct_ from 0.93 to 11; it's been through several versions since, but not all of them. This, as I said, was from v8 to v11.

        One thing that surprised me - and himself - in his account was that he spent 5 hours remotely rebuilding his rescue system, an ancient 2Gb USB device. I think I'd have just built a new one, posted it off to the colo and asked them to plug it in. (OTOH would I be happy with a colo that just plugged in a USB drive they were sent?)

          Re: Triggers Broom

          Yeah no way is it using the same motherboard/cpu/ram that it was originally installed with. That would not be 64 bit for sure. Nor would it have had USB ports at all.

            The whole exercise sounds way too much like trying to rebuild an aeroplane while in flight, or trying to solve one of those interlocking segment wooden cube puzzles, but whatever floats your boat!

            But the question is, can it really count as "the same install" if (on at least one occasion) the data/filesystems have had to be copied somewhere else (and then back again) while the actual hardware was upgraded? I suppose the 'consciousness' is the same, even if the 'body' has been replaced at times, i guess?

              Not in my mind ... Even with completely redundant fall-over boxen,"The System" as a whole might remain up according to onlookers, but if the original hardware is going up and down like a yo-yo for kernel upgrades and the like, the install has clearly changed.

                Re: Triggers Broom

                Well the Debian installer has only been used once for the installation. The root user has only been created once in the passwd file, although clearly with the password updated over time (I would hope). So yeah I think it can be considered the same install. It's not the same physical machine anymore though. I have a 486 around with Debian installed on it and upgraded for years. It was installed in around 1999 or 2000, as far as I remember using potato that was under developement because slink just didn't want to install. Haven't used the machine for about 7 or 8 years now because the poor HD sounds terrible (ball bearings don't last forever) and I don't believe Debian supports running on a 486 anymore since 2015. I think I should put a compact flash IDE disk in it and use it for DOS gaming instead. It used to be good at that before it became a dedicated linux server for many years.

                    Quite. I've migrated (Linux and FreeBSD in my case) sysdisks from old 32bit hardware to newer, either copying the installed OS or physically moving the media, sometimes needing to change a network interface name or something due to different NICs, and carried on upgrading the same OS install as desired until the next iteration.

                    Usually when the time came for 64bit hardware I did a fresh install, but it wouldn't have been strictly necessary in all cases.

                    But I came nowhere near 30 years continuous upgrades in any of my efforts, so well done there.

                  While I probably can't prove it (I might have backups from back then), the notes I made upgrading the box over the years strongly suggest that the password file is the original, and I have only created a root account once. Of course that root account has been transferred to a new boot disk umpteen times ... In your mind this is the same installation?

                  In my mind it is not. Not by any stretch of the imagination.

    LVM over RAID over LVM

    I'd love to know the reasoning behind such a structure. Is it really more reliable? More fixable? It just sounds.... precarious.

    1. Lennart Sorensen

      Re: LVM over RAID over LVM

      I suspect LVM at the bottom to allow combining different disk types and sizes into pools, then raid on top of those pools to redundancy, and then LVM on top for flexibility in allocation of the disk space.

      I have never done that, by just throwing money at the raid layer to keep things identical and hence simpler, but I can see how lvm would allow doing it cheaper and with less initial planning required for handling future upgrades.

    2. TJ1

      Re: LVM over RAID over LVM

      If this OS install has grown over time with in-place incremental upgrades it makes a lot of sense. Logical Volume Management (LVM) has gained features over the years that probably were not available when LVM was first adopted.

      Physical > LVM > RAID >LVM is probably due to LVM not supporting RAID modes originally so likely it is Multiple Device (MD) RAID - probably RAID-1 mirror.

      My guess would be originally the install was on a single HDD. As more storage is required it is far easier to manage it flexibly via OS (e.g. LVM) services rather than hardware RAID. So, add in more physical HDD/SSD, "pvcreate ; vgextend" and then "lvextend" for those volumes needing more space.

      So over time, without any major OS re-installation, using several physical HDD/SSDs, the host has a RAID mirror with OS and data volumes on top.

      Nowadays LVM supports RAID modes natively (using the kernel Device Mapper (DM) MD RAID functionality under the hood) so the additional layer could be removed whilst the OS is operating without too much trouble (I've done this on multiple systems over the years). This is one of the delights of using LVM - being able to re-shape storage architecture quite fundamentally whilst the system is live (including more exotic options like adding iSCSI block devices as LVM PVs to create remote mirrors).

      I've also done a similar live migration from 32-bit to 64-bit in-place (original 2007 install, host still in operation). Once the kernel is switched to 64-bit it supports both 32-bit and 64-bit user-space. At that point you can create a 64-bit chroot install with all the required packages followed by copying over configuration files package by package and switching the running service from the 32-bit to 64-bit in the chroot.

      Eventually you've a 64-bit kernel with a base 32-bit core running all 64-bit services. At that point the boot configuration can be pointed at the 64-bit root file-system (a Logical Volume) and the system rebooted.

      When doing this it helps to actually upgrade the 32-bit packages to the target OS version first so that the package upgrade scripts handle most of the per-package configuration file changes for you. If skipping several OS releases it's unlikely we could rely on that to correctly handle all changes and would have to manually check and review each package configuration. Once that's done the switch from 32-bit to 64-bit should be straight-forward.

    mailman upgrade

    There doesn't appear to be a way to upgrade mailman, as far as I could tell there was no real migration path from mailman 2(python 2) to mailman 3(python 3). Mailman 3 looked to be an insanely complex beast(compared to 2). I posted a few times to the mailman mailing list looking for advice and saw others in far more serious situations than my personal mail server that sends maybe 50-100 mailman messages a year. One person said they had been down for weeks trying to get the new mailman working with big mailing lists that were offline, and lots of big ugly errors trying to get mailman 3 working.

    Mailman 3 looked entirely too complex and not ready for prime time in my opinion(exception being perhaps super large lists with dedicated staff to manage it). So my solution for the meantime was to build a dedicated VM with an older Devuan release with mailman 2 and just have that do the mailman processing. My main system can remain whatever version I want and then I just have postfix route the mailing lists to that dedicated system for processing. Works fine.

    I feel I have a good knack(?) in being able to quickly determine if something is more complex than it needs to be and so I usually try to avoid such solutions where possible.

    My oldest personal system (upgraded from Debian to Devuan since) looks to date back to what looks to be about 2010, about when I switched to ESXi for my personal public servers. I think all of my servers have work have been rebuilt at least once over the years(first systems fired up early 2012). Running Ubuntu at work and when 20.04 came out I radically restructured how the VMs were configured and rebuilt everything that could run on 20.04(some things still stuck on 16.04).

    Was running Debian since 1998 with the release of 2.0. Switched to Devuan in the past couple of years.

    I estimate I spent over 100 hours of work dealing with systemd related issues at work going from Ubuntu 12.04 to 16.04 several years ago but for the most part got it all figured out there.

    I appreciate some people get attached to things like vintage cars, but they generally don't use them as daily drivers even if they have been patched and modified, migrating to some new hardware or virtual environment and fresh install of an up to date OS would seem the most prudent way forward.

    Voyager 1 and 2 were launched in 1977 and are still in operation 45 years later.

    They each have two redundant sets of three computers for operating the measurement devices, communications controllers, and positioning systems.

    Their software was upgraded, when they were beyond Saturn, to perform a type of image compression that hadn't existed at launch time. After passing Saturn, Voyager II was upgraded to send it on a previously unscheduled mission to Uranus and Neptune. In 2019 their power management software was upgraded to forestall the inevitable.

    Today, they continue to monitor conditions in the outer Solar System, although it is predicted that all scientific instruments will eventually go offline around 2025, and all communication will be lost around 2032, when the juice required to run things finally dries up.

    I once encountered a Netware 4 server that had been running since the mid 1990s on the same Compaq server. It had virtually no downtime either, apart from a PSU replacement when the fan bearing started to rattle.

    That was about 4 years ago. Nobody dared switch it off, nobody knew how to support it, it just kept going doing its little job. I will enquire to see if it’s still running,

    So not running on a 386 then

    And there was me hoping that this whole thing was still running on a 386/25 based box with a 20Mb HDD and 5-1/4" drives.

    Silly me.

    As the bloke at the Council IT department said "Look after your server"...

    Minesweeper

    Chiark also hosts a good Minesweeper clone, which only presents you with guaranteed solvable maps.

      I've had Simon Tatham's Puzzles running on every phone/tablet I've owned (reqd OS: Android 4.4 up)

    same ol' axe...

    "...relatively modern hardware, running a nearly 30-year-old OS install that's now pretty much current...."

    See this axe? I've had it for 30 years. Only changed the handle three times, and the head once, but it's still the same ol' axe...

    'Tain't broke, don't fix it.

    More surprising is that chiark as a naming still goes to just one server, rather than some kind of DNS round-robin even if it incorporates the earlier names (referring directly to a server is generally a bad idea if that server then dies...)

    But, again, I suppose that it's working so why play with it?

    I always have a dedicated server to do my stuff, only ever cheap junk from OVH or Kimsufi - lets you have an outside server to test things from, lets you provide services acts as a proxy in many regards (my websites are mostly reverse-proxied from that well-known, static IP, always-on server back to an (isolated) internal network over VPN so that you don't need hole punching and port-forwarding and TLS/SSL and other things, for instance Let'sEncrypt on my internal servers would be a nightmare to configure, but if I have the dedicated server LetsEncrypt and reverse proxy, then there's always a server online to handle all the renewals for everything, but the back-end is also encrypted and secure without having to pass ACME tests directly), and just keeps going. They usually get to about 5 or 6 years old before there's some cheaper deal involved and I migrate and upgrade across to the new server, but otherwise I just leave them running. Things tend to just keep running nowadays, I have to say.

    I'm not sure I'd be doing that level of constant upgrade because problems do creep in and I've done it several times (e.g. Ubuntu 10.04 -> 20.04 in stages) and run into problems half-way through that take an age to resolve, and at that point I'd rather clean-install and prove to myself that I have everything that I need properly recorded to recreate the configuration from scratch anyway, rather than just rely on constantly bringing forward some archaic config that I don't remember how it worked or what insecure old defaults it may still be using.

    Meanwhile in the real world

    I've just been to my doctor's surgery and been told they can't make any appointments for the next *three weeks* because they are "transitioning to a new IT system".

    Kudos to Ian Jackson for demomstrating what "IT professional" should mean.

    AC for obvious reasons.

    Been there done that

    I be had the same computer running continuously since 1991. Admittedly it has had seven hardware changes running W3.1, three versions of OS/2 and about ten Linuces from Ubuntu 6.06 to the present Xubuntu 20.04, but like chiark it's totes the same system.

    And actually, it has had the same Thunderbird profile since 1995. True.

      If you're talking about the mail client, that's quite impressive given that the first version wasn't released until 2003.
