My Upgade Dilema with FC5

I'm currently running FC5 so I need to to do something with the OS, as
well as upgrade myth and start using Schedules Direct. I have had a lot
of problems in the past with the backend crashing if I delete a
recording while something else is being recorded, even with the "Slow
deletes" enabled. IIRC the problem is the file system I'm running, which
is ext3. Also IIRC, jfs seems to be the file system of choice by many.

So if I decide to upgrade, I'm trying to figure out which OS to go with.
For me, it's either stay with the FC line and most likely jump to FC7,
or it's go with CentOS 5. From what I can tell, atrpms has the upgraded
myth packages for el5, which I believe would work for CentOS 5.

Any suggestions here?

Also, at what point do I upgrade myth? What I mean is, I'll back up my
current DB and all the associated recordings, etc. If I then rebuild the
system, am I going to run into a problem because of the newer version of
myth that will be installed? I don't think I can upgrade myth BEFORE
upgrading the OS because it looks like the FC5 yum mirrors are gone
now.

OR, do I do the upgrade, install myth, and then import from my back up
before starting myth. When I start mythbackend the first time will it do
the necessary schema updates, etc?

Thanks,
James

I upgraded from FC5 to F7 yesterday using atrpms. I did not change my file
system. The myth upgrade actually went smoothly. I had to uninstall some
obsolete packages to make yum happy, but installing the myth packages was
very easy.

A couple of things to watch out for. First, F7 has a new naming convention
for drives, so my autofs mount system had to be updated. I think all I had
to do was to change my /etc/auto.misc so that /dev/sdb1 mounted instead of
/dev/hdb1. Second, upgrading the kernel caused lirc and my nvidia driver to
break. The lirc issue was simple. I installed the correct package from
atrpms. I couldn't get the nvidia driver from atrpms to work with my new
kernel, so I downloaded nvidia's installer. That worked fine after a reboot.

James -

First off, I wouldn't try to go with Fedora 7. My understanding is that
there are known problems with anaconda on Fedora 7. I would consider either
FC6 or CentOS for now. I've been using xfs with no worries (when I set up
initally, jfs was reported to be problematic for some, not so now).

FWIW, An upgrade to FC6 and a "yum update" to get the latest packages from
Axel and running mythtv-setup followed by mythfilldatabase was all that was
required to get my combined Frontend/Backend transitioned from Zap2It to
SD. I might be tempted to go that route for the moment, and do the CentOS
upgrade at your leisure.

Hope that helps...

Chris, how did you upgrade to FC6 - with a DVD or did you just upgrade
the packages?

I actually did it via a "yum upgrade" process. I was advised against trying
it, but I had a dead optical drive in the Mythbox, so I gave it a shot. I
need to finish up my notes, then I'll forward them on.

I just went through upgrading my frontend systems and my backend system
from FC6 to Fedora7, and I personally didn't have any troubles with
anaconda. Additionally, my main video filesystem is ext3 with ~500GB of
recording video storage (about 76% used). I would probably see better
performance using jfs or xfs, but that'll be something I tackle at
another time. :)

My understanding is that not everyone does have trouble with F7 anaconda,
but if you do it's a nightmare.

I decided to go ahead with a new install, because right now is the best
time to do it (before the TV season starts).

So I started the install for CentOS 5 and find that my only options for
file system are ext2 and ext3. Do I need to install the system as one of
these on a smaller partition, then add support for JFS afterward, then
use the rest of the free space? That seems to be the case, but want to
make sure.

Thanks,
James

Nothing wrong with using ext3 for storing your data. You may need to look for a
"large file" (I think) option when you are formatting the partition, so you
don't end up with your video files scattered all over the disk. Works fine for me.

I had a go at FC5 to FC7 with the DVD recently and had the problem
that X wouldn't start, probably because it didn't have the right
nvidia driver version and kernel modules, so I had to roll back.

What commands need to be run to get the right version of nvidia
packages and kernel modules for nvidia, lirc and alsa? The thing I
especially don't understand is getting the right nvidia packages -
because I don't understand how you are supposed to know the nvidia
version number which you need before you try to "yum install" it.

Do a rpm -qa *kmdl* or rpm -qa *nvidia*, you can even go so far as to
add " | grep" and put the name of the last working in there. That
should give you the listings for all the various kernel modules you
have installed. Then simply make sure you do yum install for all the
kernel modules. If you used Jarod's guide, you can even do yum
install lirc-kmdl-$KVER (and likewise for the other modules).

Or, you could install smart, (yum install smart), and install the
correct package to enable axel's atrpms smart repos, and do smart
install lirc and likewise for alsa and nvidia-graphics.

Yep! I reinstalled my MBE on a couple of days ago from FC5 to Centos5.
The data partition was (and still is) xfs. So I installed on existing
partitions (/ and /boot), and left the xfs partition alone. (This may
not be applicable in your case.) It went down like this:

1. make full backup of host
2. make full backup of database (which I forgot to do - D'oh!)
3. install Centos5 onto existing / and /boot partitions
4. install additional repos
5. install kmod-xfs from centos extras
6. patch
7. install additional services
8. install myth dependencies
9. restore /var/lib/mysql (because I, like a dumbass, forgot step 2.
Fortunately, I got lucky in that it worked.)
10. restore /usr/local/src (which is where I keep my copy of myth svn)
11. build myth (same version of before)
12. Test and tweak. Repeat until satisfied
13. make full backup of the system

If not too tired from the above steps, then I'm safe to take the plunge
going to a new svn version. And I was too tired on Saturday. So I did
the svn upgrade Sunday...

My Upgade Dilema with FC5 [In reply to]

Chris,

Please post the command line you used to update FC5 to FC6 using ATRPMS.
I don't seem to get anything for FC5 from ATRPMS and I haven't been
able to figure out how to update the kernel from one FCx to another FCx.

Thanks for your help.

It will be up this evening (I don't have my notes here). It is a multi-step
process.

Per Joe's Request. Here is how I did an upgrade from Fedora Core 5 to
Fedora Core 6 on my MythTV combined Frontend/Backend. The system was
originally built from Jarod Wilson's excellent instructions. While this
worked for me, your mileage may vary.

1. Run the following as root:

# yum -y update

It may not be actually needed, but it seemed to make sense to get the
FC5 install up to date before proceeding with FC6.

2. # yum clean all

To remove all the old yum �leftovers�

3. Turn off all of the �non-Fedora and not atrpms� repositories. There
may be version conflicts between repositories, and it is best to use
just the Fedora and Axel's repos at this point. Either edit
/etc/yum.conf to remove references to the other repositories, or go to
/etc/yum.repos.d and rename the non-Fedora .repo files to remove the
extension. i.e.:

# cd /etc/yum.repos.d
# mv freshrpms.repo freshrpms

etc., etc., as needed.

4. Now bring over the FC6 release info. Note: the following is all one line:

# rpm -Uhv
http://download.fedora.redhat.com/pub/fedora/linux/core/6/i386/os/Fedora/RPMS/fedora-release-6-4.noarch.rpm
http://download.fedora.redhat.com/pub/fedora/linux/core/6/i386/os/Fedora/RPMS/fedora-release-notes-6-3.noarch.rpm

5. # rpm -ev vcdimager

I hit a dependency loop with vcdimager, this got around it. If you tend
to mess with VCDs, you will want to add it back after step 9.

6. # yum -y upgrade ivtv

I hit a dependency snag (I think it was the same one that Larry Roberts
and Axel Thimm were discussing on the list) involving ivtv-kmdl and
vmlinuz versions. As an attempt to narrow down the problem, I tried just
upgrading ivtv, and it found and pulled in the appropriate kernel and
ivtv bits. Sometimes, even a blind squirrel finds an acorn.

7. # yum -y upgrade

This will upgrade the rest of the system, including MythTV, to the
latest FC6 versions.

8. Reverse steps 5 and 3, if you feel you need to.

9. Reboot, and (for me at least) all is good.

I hope that helps someone...
