lhaven upgraded

AKA the end of RedHat 7.3.

For sometime, I have thought that it was time to upgrade 'lhaven' to a more modern release of Linux.

For the longest time, 'lhaven' has been running RedHat 7.3 (it was 7.2, but then I discovered Fedora Legacy...and they were providing patches for RedHat 7.3) And, there are still some production servers running this release, but I no longer have to support them...as I no longer work there.

The problem was that I had compiled a lot of custom apps over the years, that would be difficult to upgrade to newer distro/release of Linux. Since they were done without though to going to a different distro. 'lhaven' did used to run older versions of RedHat, and had been upgraded to where it stopped. But, to go to another distro would require a major effort. And, some of the apps were hard enough to get working to begin with. And, were some what fragile.

'lhaven' has also gone through some hardware iterations. The first major was when the Cyrix 233 that it was one burned up (a transformer had blown a phase, causing really low voltage before it went out....) though more likely it was its return after the outage with none of its fan able to spin. It was working for a while...but then there was smoke, and it all ended.

Got a Duron 800Mhz machine, which grew to an Athlon 2000....and had its motherboard replaced after the icepocalypse. The icepocalpyse was the first time I had to seriously look at upgrading from the old RedHat 7.3....but later I found a compatible motherboard and got the system to boot. The machine I bought at that time became 'orac'.

Later my use of ReplayTVs dropped off, and the one of the main apps that used datadirect for guide data was never successfully updated to support the newer schedules direct service. And, that was one of the things I didn't want to touch. But, now it is gone.

More recently, I started moving some of the other things that ran on 'lhaven' to 'box'. Namely, MRTG and cacti. I also updated all my linux servers to be able to handle mail for my home network, with the local mailboxes on 'box'. Also moved secondary DNS to 'orac' (someday I plan to get fallback DHCP on 'orac', but that'll probably come later.....) During the icepocalypse I had moved DHCP and primary NTP and DNS to 'box'....'lhaven' came back as secondary, because the old 'gumby' was sufficiently broken that I couldn't get it to not require 'lhaven' to function.

So, what I did was install ubuntu-10.04-alternate-i386 to become the new 'lhaven'. Which was the suggested to do RAID at the start, it had been a long time since I had done it, but the last time I had...it was a server install. But ubuntu no longer supports 32-bit hardware as servers, but both 'lhaven' and 'box' are 32-bit machines.

Took some figuring out, but its all done now. Yes, there's a desktop on all my Linux boxes, though 'lhaven' doesn't seem to be really up to the task. The video seems pretty poor and fuzzy compared to the other Linux servers. Perhaps I'll see about replacing its integrated video with an NVidia card of some sort...what that does CUDA, though it'll have to be a PCI card.

Anyways....after the install was done, I installed a few basics...like boinc and called it a night.

Today I continued the work on getting it to run all the stuff I needed, at first I was going to reconfigure its postfix to be more than just a satellite system, sending everything to 'mail' (CNAME of 'box').... the old days 'lhaven' was the center of my 'lhaven.homeip.net' network.

But, when I got postfix reconfigured, I discovered that something on the new 'gumby' is configured to use 'lhaven' as its MTA....probably something I restored to it that predates the 'mail' CNAME on my home network.

Another (annoyance?) thing that I discovered is that the Xfer type of a backup done using backuppc has to be the same for both backup and restore...even if they are between different hosts. I was trying to repopulate a directory on the new 'lhaven', by restoring from the duplicate share on 'orac' (instead of restoring the old 'lhaven' data...because 'orac' has an updated directory organization, and stuff that hadn't been duplicated to 'lhaven'...) backuppc by default uses 'tar' for localhost backups. And, globally the default is 'rsync'...which is how I do backups of most of my other Linux systems. But, it just wouldn't restore the data. I tried google, but the only related thread pointed to ssh as the problem, it wasn't.

The restore of old 'lhaven' data to the new 'lhaven' had worked, so I it wasn't an ssh problem....so I had to figure it out on my own.

But, I think I have everything the way I need them to be on 'lhaven', so I've kicked up the first full backup of the new 'lhaven'.

Now to figure out what's for supper....

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
