Support for Debian 7.0

john — 2013-05-24T06:48:03

Hi,

I've updated my own internal machines to Debian 7.0, and am reviewing
possible issues with upgrading our customer machines.

The most obvious issue right now is support from mondorescue (actually,
probably, mindi): right now the ISO fails to find disks or CDs because 
of
"missing" libraries. I've attached a transcript of a mindi session 
which
shows it going through the motions, but almost everything except 
busybox
itself fails - most importantly in the first instance, no modules can 
be
loaded.

For reference, here's the libraries required for some relevant binaries
on the live system:
   john< at >cedar:~$ ldd /sbin/insmod
linux-gate.so.1 =>  (0xb77db000)
libkmod.so.2 => /lib/i386-linux-gnu/libkmod.so.2 (0xb779a000)
libc.so.6 => /lib/i386-linux-gnu/i686/cmov/libc.so.6 (0xb7637000)
/lib/ld-linux.so.2 (0xb77dc000)
   john< at >cedar:~$ ldd /sbin/lsmod

Re: Mindi bootdisk can't find libkmod.so.2, can't mount external storage

Will Hopper — 2013-05-23T18:56:14

Hi Bruno,
Adding /bin/kmod, libkmod.so.2, and libkmod.so.2.1.3 to minimal.conf
succeeded, I was able to make a bootdisk calling mindi solo. I will try it
through mondo now. Here are the outputs of those commands you asked about.
I also attached the mindi log from this run so you can see the difference.
Just a note, could the problem have to do with symlinks? On my system,
/sbin/kmod and /usr/i386-linux-gnu/libkmod.so.2 are symlinks.


"ldd /bin/kmod'" output:

        linux-gate.so.1 =>  (0xb7734000)

here from existing grub2 users.


Maybe can't see that myself.


Maybe you don't think so but I tend to disagree !! If you want me to
start supporting it better for your case, then you have to provide these
logs. I may ask additional questions, improve what the log reports for
future versions to give me more hints, but that's a mandatory start.

Work around: Add it to /etc/mindi/deplist.d/minimal.conf

Could you provide the result of ldd /bin/kmod please ?
And also the result of mindi --locatedeps /bin/kmod
and also of the following bash command:
for i in  `sudo /usr/sbin/mindi --locatedeps /bin/kmod`; do echo $i ; echo "----" ; sudo mindi --readalllink $i ; done

Fedora 17 and grub 2...

NA — 2013-05-20T18:52:01

Are there special instructions for getting mindi-2.1.5 to work with Fedora 17?

Mindi bombs out with cannot find grub.  I think mindi is expecting  
grub 1 instead
of grub 2.

I'd attach logs, but there doesn't seem to be anything useful in them.

Mindi bootdisk can't find libkmod.so.2,can't mount external storage

Will Hopper — 2013-05-19T02:26:33

Hi all,

I'm having a problem with my mindi boot disk functionality. When booting
from the usb, I get an error "can't find libkmod.so.2", when modprobe is
called during mounting the usb. The lib file is not in the ramdisk, so this
is accurate. However, the mindi log shows that the file is included. Adding
it to deplist.txt has no effect. This is reproducible using both mondo, and
mindi independently of mondo, and with versions 2.1.4 and 2.1.5. The system
I'm backing up is debian testing (jessie), with libkmod2 version 9-3.

Is there a way i can force this to be included, perhaps with a line in
/etc/mindi.conf?

Humm, understood. I don't think it should matter as this is just in the
file list used by mondo, I don't think it has an impact on the restore

As it was simple to change, and I had the patch in the 3.1 branch, I
applied it so it will be in 3.0.4.

2 small troubles to finalize a DR with mondorestoreon Ubuntu distro

Philippe Lefevre — 2013-05-12T07:48:53

Hi list,

To let you know 2 small troubles I had in case it may help.

Booting from a mondorescue CD, I successfully restored my linux ext3 and 
LVM partitions but at the end of the process, I had an issue with the 
advise to use mkinitrd.

My distro is Ubuntu 10.04 (I know it is pretty old, but I need a good 
backup before to upgrade it ;) ).
Ubuntu doesn't use mkinitrd anymore but initramfs instead.
(Mondo Rescue release is 3.0.3-r3091)

IMHO, in order to help all of those like me, are not familiar with the 
boot operation, it may help to mention it in the message displayed by 
mondorestore just before to get chrooted.

Another small issue: My device /dev/sda7 is a LVM2 partition (0x8e) and
a line containing "/dev/sda7    lvm" was written into fstab.
It causes some errors while booting. This line should be removed.

Regards,
Philippe

yes; That doesn't work except if your other computer is similar from a
HW perspective as well as from a SW perspective.


Yep, and it may even not boot if it doesn't have the right drivers in it
to support your other computer.


Hopefully it will help you bringing your system back to normal.
Another way, which is *always* available. Boot from your preferred
distro media, make your partitions install the strcit minimum. Then use
mondorestore interactively to restore everything. Or use afio manually
to extrac all the content from the backup.

Your data are always there.

Re: Mondorestore keeps asking to "Insert isofs #1"

Will Hopper — 2013-05-10T02:04:53

Bruno,

Sorry my explanation was so confusing, trying to keep all the little things
straight has been confusing to me too!

The backups were made directly to an iso (boserv-1.iso) on an external
drive, not bootable. I had assumed that if I had system failure, i could
use a mindi disk from another computer to boot and then just use
interactive mode to point mondo to the correct paths.........wrong!  The
mindi disks boots, but I forgot about the mountlist and filelist and all
those config files, so the restore would not produce the best results I
don't think....

So, I decided to make the backup iso (boserv-1.iso) bootable as per the
instructions on the FAQ. These instructions have worked fine to make mindi
boot disks on other computers, but for some reason I can't boot from this
backup after following the instructions. I just get 'boot error' from the
terminal. The disk is bootable, because if I try to boot from some random
usb with normal files, the terminal tells me "this disk is not bootable,
try this or t

Will Hopper said on Thu, May 09, 2013 at 10:52:20AM -0700:

It's difficult to help without knowing how you did the backup. I'm not
sure I understand the issue: the image is normally bootable (except if
you used -W) but to boot on it you need either to burn a media, or to
use a virtual media (if your HW provides one) or to make a PXE restore
using the content of the boot area and following the README.pxe of
mindi.


This is probably a boot loader issue. Either it tries to boot using
files that have been removed during your upgrade, or it treis to boot a
media which is not really bootable.


I think that's the wisest approach in your case. Or making USB devices.
I've increased the priority to solve the external ISO issue, but anyway
this method will require to boot at least from a first media, and for
you it will be too late :-(


Try un-mounting/mountig the ISO manually to see if that helps. Also the
name may be a problem. Some suggestions were made in that BR:


Best regards,
Bruno.

Re: Do am I the things right [Resolved]

Philippe Lefevre — 2013-05-09T19:40:42

Hi list,
My procedure seems ok and it is well possible to use a tree like mine to 
save the iso files. I was able to restore my linux from iso files this 
afternoon.
I just need now to complete my tests until I can boot this new disk.
In fact, I did a stupid mistake with the device names
I used /dev/sdf instead of /dev/sdg. It seems that the usb disks are not 
named the same way if they are plugged before or after boot.
Sorry for this.

Philippe

Yeah SamK, thats exactly how it went for me, had to move it to the root of
the drive for it to find the config files and everything. There are some
complications though.
I've got a screen now, and I had to hack together the mindi boot disk using
one from another computers backup, and putting in the correct the correct
file lists, and mountlist, etc. This was because I couldn't make the iso I
stored on my external drive bootable following the instructions on the FAQ
page, no matter what I tried, I couldn't get to the boot prompt, the screen
just read out 'boot error' and stopped. Anyone have any idea what that
might mean?

In the mean time, I'll burn it to a CD and hope for the best!

 This situation has been faced here for a year.  It is a major concern.
The only reliable workaround I can find is to burn the backup ISO to CD/DVD
and then boot the system using this.  The backup can be restored from the
CD/DVD.  It is a far from desirable solution but until the issue is
resolved it may help get your system running again.

Philippe Lefevre — 2013-05-08T23:10:28

Hi list,
I'm afraid that's the way I build my backups is wrong.
Anyone could tell me if/where I'm wrong?

I'm still not able to restore any NTFS partitions so finally, I had to 
use a simple dd gziped.
Then, doing some tries with linux partitions I am facing quite a similar 
issue: mondorestore always displays config/archives files are not found.
As I know this software is well used elsewhere, I suppose my procedure 
somewhere is wrong.

I have a 1To usb disk to save mainly 2 systems (1 server and 1 laptop).
It is organized like this:
The disk is mounted as /media/svg
server/distro/timestamp/syssys_timestamp-1.iso
sys_timestamp-2.iso
....
server/ntfs/timestamp/vistavista_timestamp-1.iso
vista_timestamp-2.iso
....
laptop/distro/timestamp/syslap_timestamp-1.iso
lap_timestamp-2.iso
....
laptop/ntfs/timestamp/xpxp_timestamp-1.iso
xp_timestamp-2.iso
....

- replace the main disk by a new empty hard disk already partitionned

Hi all,

Due to an unfortunate series of events, my debian server got interupted
during an upgrade to the new 7.0, and was very confused about what to
install. So, I thought I would just restore, and start over on the upgrade.

I launched mondorestore over an ssh connection, chose restore from hard
drive, selected the .iso from my external drive, selected my files, and
went to restore. Then i was asked to "insert isofs #1 and press enter", but
it never could locate the iso, and I couldn't interupt the process. I could
hear the disk drive moving each time I hit enter

I was forced to kill the terminal, and I could not open another ssh
connection to try again. I had to restart, and now the system is
unbootable.

I can't get logs off the machine right now, have to borrow a screen so I
can boot it up from a restore disk. What can I do to get mondorestore to
get find the iso?

Re: Mondorescue - backup over NFS wants to restorefrom CD

Will Hopper — 2013-05-06T01:43:10

This happened to me when I was trying to boot from the wrong device. In my
case, I burned the /var/cache/mindi/mondorestore.iso to a USB and made it
bootable per the documentation instructions here:

http://trac.mondorescue.org/wiki/FAQ#Q42HowtotransformamondoCDDVDintoamondoUSBdevice.


When booting, mondo was guessing the wrong device node for the USB, it was
guessing /dev/sdb, but my USB was really /dev/sda, and it wasn't able to
unpack all the tools that aren't built into the initial ramdisk, like the
mondorestore command. Try using the boot paramter USB=/dev/sda or some
other /dev/sd* at the prompt where you would specifcy interactive,nuke, or
advanced mode. Leave off the partition number. In my case, this message had
nothing to do with finding a CD or CD drive.

Also, if trying different devices doesn't work, make sure to include your
mondoarchive, mindi, and mondorestore log. The restore log should be in the
/tmp directory of the boot device.
