I think I did answer this once before David, but I was useing what looked 
to be a simple install, 1 up from the advanced gui install at the bottom 
of the start screen list.

I've been busy getting a verdict and script from the doc today, bought a 
new shredder to replace the one that has a split personality, then 
caring for the missus, and have not tried another install, but will 
tommorrow using the Advanced mode.

I think you would find researching and understanding the d-i advanced

It does shut the installer up from complaining about the drive has data 
from an old install though. :) And its too late to restart another 
install tonight.  And I have an appointment with my GP tomorrow to 
discuss the protein levels in my liquid output. So we'll have to see 
what that leads to.

I've been scratching my head trying to remember the details of bootloader
installation in debian-installer and coming up nada, except for somehow being
able to specify /dev/null as location, let it complain about bootloader
installation failure, and not have it corrupt my existing bootloader
configuration, which always includes generic/legacy compatible MBR code.

I figured I'd mount it to wheezy and copy over my personal stuff,
like an email corpus well over 15GB reaching back to 2002.

But I can't mount much of the drive, / is all that will actually
mount, because the 2 versions of ext4 are incompatible, nearly all
the mount and e2tools can't touch the installers ext4 file systems.

For instance, its not mounted:
gene@coyote:~$ e2fsck /dev/sdb8
e2fsck 1.42.5 (29-Jul-2012)
/dev/sdb8 has unsupported feature(s): metadata_csum
e2fsck: Get a newer version of e2fsck!

And of course whats installed to wheezy is the latest available
wheezy version of e2fsck.

Whats the recommended way to do these mounts so I can maintain as
much continuity as possible?

Thanks all.


Hi Gene, I've seen this before, a few times. If you run #fdisk -l
while in stretch and get error, you need to fix that first, using
gparted move the ailing partition '1'byte, just one digit larger or
smaller, if you have to shrink another partition, do it '2'bytes. UUID
will not change and it will pass fdisk -l no error.  Now in wheezy see
if you can mount. If not you can disable the checksums. To disable
checksums on an existing filesystem, ensure that the filesystem will
pass fsck. Then turn off metadata_csum via tune2fs.
   #tune2fs -O ^metadata_csum /dev/path/to/disk

The above is for ext4, for repairing partition I use this with force.
   #fsck.ext4 -pvcf /dev/sdxx


Thanks Jimmy. I haven't gotten that far, as I've done 6 or 7 installs
today and it will not install grub on anything but /dev/sda.



Run #fdisk -l, only takes a moment...If you have a bad partition-table, 
formatting will not fix it.

Just think of all the time you might not have wasted if you'd just told 
us what the problem was when you tried to mount the partition. Because
what you're trying to do works perfectly well here without all this

Thanks Jimmy. I haven't gotten that far, as I've done 6 or 7 installs 
today and it will not install grub on anything but /dev/sda.

So now I've swapped the drives so that the new one is sda and this one 
I'm booted from is now sdb, and am about to reformat it to suit me with 
wheezy's gparted, then try another install. Broken damned installers. 
After the last try, I rebooted to the dvd in live mode, thinking I could 
do a grub-install from there, only to find that that boot had no trace 
of the grub tools.

What a revoltin development that was!

Damned dvd has 3+ gigs of empty space and they can't find room for grub2 
tools?  Good Grief, they're staying up nights trying to make a stretch 
install come up broken on the reboot.

I'll be useing my bigger lathe to make a big piss-elm club, same one I'll 
use on the next person that thinks north of 70 yo is the golden years. 
I'll call it my educational club. ;-)

So its off to do the 8th install to the same hard drive today...

Debian has never put network interface device nodes in /dev.  I don't
know why you expected to see them there.

If you want to learn the names of your network interfaces, there are
several commands that may work:

ip link
netstat -in
ifconfig -a

On any given release or installed-instance of Debian, one or more of these
may not be available, so learn 'em all.  "ip link" is the preferred one
these days, so I put it at the top of the list.

Re: painted into a corner

[Timothy M Butterworth]

I like network manager when I'm out and about with my notebook it
works great for connecting to wireless hotspots. It does what it was
designed for.

The new udev naming convention does look strange but at least udev no
longer randomly flip flops the nics on my UTM putting the inside
ruleset on the outside interface and outside ruleset on the inside
interface. It would have been better if they could have kept the eth0
style convention and used a file to keep persistence in the naming and
activating.

Ahah! That's where home cooking comes in of course - check the
glycaemic index on various alternative sweeteners (e.g. stevia), and
experiment with some combination, to keep the total for a medium
sized cheesecake below your daily "glycogen" intake requirement -
sour cream, some matured/Euro-style cream cheese, perhaps buttermilk,
touch of fresh lemon juice and BAM, no more than a day's glyco intake
in a full cheesecake!

And if you go full keto ("ketogenic") for a couple months, you can
eat these every day AND lose weight - seriously the ultimate
indulgence diet - it doesn't get better than this.

Hi Gene, I've seen this before, a few times. If you run #fdisk -l while 
in stretch and get error, you need to fix that first, using gparted move 
the ailing partition '1'byte, just one digit larger or smaller, if you 
have to shrink another partition, do it '2'bytes. UUID will not change 
and it will pass fdisk -l no error.  Now in wheezy see if you can mount. 
 If not you can disable the checksums. To disable checksums on an 
existing filesystem, ensure that the filesystem will pass fsck. Then 
turn off metadata_csum via tune2fs.

 #tune2fs -O ^metadata_csum /dev/path/to/disk

The above is for ext4, for repairing partition I use this with force.
 #fsck.ext4 -pvcf /dev/sdxx

Neither do I, ackshualley - except on computers I install for others,

Yes, I still don't understand why you install stretch but then run
wheezy. It's normal for modern systems to understand older formats,
but old systems' authors can't foresee future features. Say that fast.

That's what I'd do - just boot stretch and mount your wheezy
partition(s).  Newer OSes are designed in general to be backwards
compatible - people scream at the sky when a previous disk cannot be
mounted.

That was probably "navigating to my old /home/ folder" perhaps?

You need to mount your original partition for /home I suspect, not
just the root partition, that's all...

It's possible you shut down too quickly?  Or could the drive have
been disconnected before unmounting the old wheezy /root ?

Hm, frustrating.

Networking should work roughly the same in both wheezy and stretch.

If you want it auto shiny, just apt install network-manager

That was the output of fsck, not the output of mount. But at least 
you've provided another wall of text.

If push comes to shove, I'll see if a wheezy disk can be mounted to a 
stretch mount point. Someplace in the last 2 days ISTR trying that after 
booting stretch, and mount worked but navigating in the disk failed, the 
root was all I could see, and when I rebooted to wheezy, I had a 15+ 
minute pause while it did an e2fsck to most of that 1 terabyte disk, 
without reporting any errors found that it told me about on the boot 
screen. That would spook most anybody I think.

But now, for no known reason, stretch's network has gone away.  And all 
the tools I am familiar with have been excised from stretch.  Sigh...

Thanks Brian.

If you had read that wall of text, the error was that the new version of 
ext4 supported stuff the wheezy version didn't and it recommended 
getting an updated e2fs-utils, which of course is not available in a 
wheezy repo.

So I reboot to a different installer supplied by the linuxcnc people, and 
installed it. Weird, I had access to the network, and could download 
updates, but when I looked in /dev/ no sign of either eth0 or enp0s8.  
Installed some more stuff with aptitude,logged out and rebooted to that 
install, and now my network is dead.
So, working from a terminal, I've tried to configure it manually, and 
that fails, so I am now back on wheezy, which Just Works. And I've no 
quick and dirty way to copy/paste those errors after a reboot, isolating 
that filesystem from wheezy. 

If you want to help, give me a link to a printable tut on how to make a 
working static, host based for local lookups, but uses my router, which 
in turn will forward the dns requests it cannot answer from dnsmasq, to 
real servers on the outside network, like my isp's network. On stretch.

I've read the gibberish man page for ip & friends, since ifconfig is 
gone, and apparently so it route, but gibberish  is the correct term 
when there is not a working example line in the whole man page just to 
prove it works.

So I've zero network troubleshooting tools when booted to stretch.  And 
you are giving me what for, but zero help.

So show me a tut which I can use to make it work, Mike.

Boot the installer and stop when you get to partitioning.
Switch to a console (ALT-F2) and mount the wheezy and stretch
partitions. Use cp to copy files between the two partitions.

Boot the installer and stop when you get to partitioning.
Switch to a console (ALT-F2) and mount the wheezy and stretch
partitions. Use cp to copy files between the two partitions.

I'm sure you would. But for all of your wall-of-text ranting, you failed 
to ever provide basic information like "what is the result of trying to 
mount the partition" so we're left guessing here.

sudo reboot doesn't unmount the system drive cleanly enough? Then I'd 
call it a bug.

And my wheezy kernel is
gene@coyote:/$ uname -a
Linux coyote 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.39-1+deb8u1~bpo70+1 
(2017-02-24) x86_64 GNU/Linux
Which is not pinned and the machine is updated about 2x a week.

Sometimes they can be educational, and I try to make mine so if you can 
get past my frustration, but in this case its partly my own fault, a 
naming confusion on my part, I had put the wrong dvd-1 for 9.4 in the 
reader, when I should have used the adapted stretch from the LinuxCNC 
guys. I have now burned that one, and if I don't install a desktop at 
all, then my tde install will be clean and hopefully uncontaminated by 
what is obviously a broken gnome. Trying to make it look and run like 
windows 95 is IMO a huge mistake, but one that I must say debian has 
done remarkably well. Bring back the pulldown text stuff where 2-3 
clicks gets you anything installed.

If you unmounted cleanly you don't need fsck. Install a newer kernel 
from wheezy backports and it should mount fine.

On boot enter: knoppix 2

I have a few versions of /etc/ backed up - most of what I ever need
in a new install (physical or VM) is in there.

The rest is somewhere in /home - but when installing clean after
skipping a version of Debian, I prefer to move ~/.config/ to a backup
location, before logging in the first time, then just customize till
I get things reasonably the way I like - and I can always grep
through my old .config just in case...

So apart from a little command line mounting of old stuff
occasionally, but in the new system, I always boot into my new
system.

SO, re your grub setup - and since you're now in your old install -
you might configure old grub to know about the new install, and
update grub to the HDD accordingly. In fact, I would also install a
grub that recognizes all my installs, to BOTH HDDs!

That way you can always boot into something.

Other than that, as soon as I can start working in my new install,
the better as far as I'm concerned.

As a mountpoint, perhaps /media/wheezy for mounting your old root, or
vice versa?

Good luck,

Migrations are much easier when you have additional computers and parts 
drives to help.  I have a dedicated file and version control server.  I 
also have a machine for backups, archives, images, and whatever else 
(workbench).  All of my machines have HDD/ SDD mobile racks, so it is 
easy to move drives around.



I prefer small SSD's for system drives -- 16+ GB.  I use large HDD's for 
file server data drives and for storing backups, archives, and images. 
I would use that 2 TB for one of the non-system drive purposes.



When I want to upgrade a machine, I ensure that all of the configuration 
files are checked into version control and that all the data is backed 
up/ archived.  I pull all of the drives, and take an image of the system 
drive.  The old drives go on the shelf, in case I want to revert.



Next, I insert a wiped 2.5" SSD system drive into the target machine and 
do a fresh install.  I take an image of the system drive.



Next, I install applications, adjust configuration files, restore data, 
etc., adding drives, taking notes, and using version control as needed.



Once the rebuilt machine is complete and operational, I integrate it 
into my backup/ archive system and take another image of the system drive.

That is what I'll likely do when I next boot to it, but the tools to make 
that easy are often in the missing list. I did get synaptic to install 
mc, but had all sorts of perms problems I didn't expect when I tried to 
use it, due I think to the changes in what says is ext4 on both disks. 
We will eventually get it sorted I hope.  So I'll be, without a doubt, 
back with more problems but hopefully making progress over the next week 
or so. Progress always puts me in a better mood than I was for the first 
post in this thread.

==

It will be a week down the log when I get to it, but I absolutely must 
figure out how to get ssh -Y to work again.  Works flawlessly wheezy to 
wheezy, but wheezy to Jessie and wheezy to stretch is a no-go from the 
gitgo.

X11 forwarding request failed on channel 0, is the error.

It also fails like that from jessie(on an rpi-3b) to stretch(on a 
rock64), but not from stretch to jessie, but still won't let geany run, 
reporting "geany: can't open display".  So there may be 2 show stoppers 
to fix.  Sigh...

I just rebooted to it, and I found a desktop interface that will wear out 
a set of batteries in my mouse weekly because it takes at least 8 to 10 
clicks and some scroll wheel work just to find a #@%# terminal, and it 
can't even add tabs to a different shell either! I didn't install 
anything special for a desktop, took the default because I intended to 
replace it with TDE asap, and going from 10 workspaces, 4 of which have 
multi-tabbed (up to 7 tabs each) konsoles running on them, with a 
pulldown text menu to run half the stuff I run on the other workspaces, 
to a single window, single tasking system thats worse than the last 
windows box I was asked to configure the networking on, was very 
disheartening.  So I added the trinity stuff to /etc/apt/sources.list.d 
using mc to copy that from the old disk, changing the wheezy in the deb 
line to stretch, and that did not get me the TDE desktop I've been using 
for years, but did get me some sort of a warning window that was taller 
than my screen, fussing that some repo I hadn't added, was duff. If 
debian is trying to kill itself, it was a heck of a good start, not even 
a windows user looking for something better would be impressed.

The only thing that Just Worked was the networking, it took everything 
for a static net and Just Worked on the reboot.  That was a rather 
pleasant surprise considering the only stretch based install on my 
rock64's that works at all was armbian.  None of the other arm|hf|64 
*bians will accept a gateway assignment except as as a route command 
after a login.

I'm burned out for today, my cataracts might have to be the next thing I 
fix.

Can you not run your stretch installation then? In a new system, I'd
mount the old wheezy disk(s) and pull the files across. Leaving the
wheezy mount there makes it easy to look back at the old system in
case you forget a file or just want to see how you used to do a
particular something.

Cheers,
David.

In those cases I usually boot a recent live-CD (or USB-stick) like KNOPPIX and 
mount and copy from there.

Greetings all;

I just installed stretch to a fresh 2T HD. letting it autopartition and
format for separate /, swap, /var and /home partitions. But I didn't let
it overwrite the grub on the 1st drive it was/is  booting wheezy from.

I figured I'd mount it to wheezy and copy over my personal stuff, like an
email corpus well over 15GB reaching back to 2002.

But I can't mount much of the drive, / is all that will actually mount,
because the 2 versions of ext4 are incompatible, nearly all the mount
and e2tools can't touch the installers ext4 file systems.

For instance, its not mounted:
gene@coyote:~$ e2fsck /dev/sdb8
e2fsck 1.42.5 (29-Jul-2012)
/dev/sdb8 has unsupported feature(s): metadata_csum
e2fsck: Get a newer version of e2fsck!

And of course whats installed to wheezy is the latest available wheezy
version of e2fsck.

Whats the recommended way to do these mounts so I can maintain as much
continuity as possible?



Maybe using apt-pinning.

In other words, installing the version of Stretch/Jessie on wheezy.

On the wheezy host, can't you backupt on an external hardware?

Greetings all;

I just installed stretch to a fresh 2T HD. letting it autopartition and 
format for separate /, swap, /var and /home partitions. But I didn't let 
it overwrite the grub on the 1st drive it was/is  booting wheezy from.

I figured I'd mount it to wheezy and copy over my personal stuff, like an 
email corpus well over 15GB reaching back to 2002.

But I can't mount much of the drive, / is all that will actually mount, 
because the 2 versions of ext4 are incompatible, nearly all the mount 
and e2tools can't touch the installers ext4 file systems.

For instance, its not mounted:
gene@coyote:~$ e2fsck /dev/sdb8
e2fsck 1.42.5 (29-Jul-2012)
/dev/sdb8 has unsupported feature(s): metadata_csum
e2fsck: Get a newer version of e2fsck!

And of course whats installed to wheezy is the latest available wheezy 
version of e2fsck.

Whats the recommended way to do these mounts so I can maintain as much 
continuity as possible?

Thanks all.
