Verification on Syntax Questions

Hi there --

I am running mondoarchive as part of a cron script, and I have been asked to verify the syntax that I am using is correct.

The command in question is shown below:

/usr/sbin/mondoarchive -9 -N -O -s 650m -S / -T /tmp -p <hostname> -n <nfs server>:/<hostname> -E -I "/boot /"

The questions that have been posed concerning the command syntax are the following:

1. Will the above command syntax back up the filesystems as opposed to the devices?

2. Is it better to back up the filesystems, or should I back up the devices?

3. One filesystem that was not included in the -I arguments was the /dev/shm filesystem.
    Should that be included, or is not necessary?

The reasoning for the first two questions is the possibility of replacing the physical server with a newer one, and
for the relative ease of porting the existing filesystems into a new physical environment.

Thanks.

Re: Verification on Syntax Questions

Hi Andrew,

I'll have a go with what little I know.  (Poem, there.)

The -E is for exclude.  If you are going to use it you need to provide
the blank-delimited list of directories to exclude.  By default the
list is what you would want, and excludes the pseudo filesystems such
as /proc /sys ...  which means you probably don't even need that
option. If you had large data somewhere you were backing up outside
your disaster recovery backup (mondoarchive)-- let's pretend
/usr/local/gallery and /usr/local/images -- you might use: 
	-E "/usr/local/gallery /usr/local/images"

Opinion, NOT a rule:
* I would point -S somewhere besides / (root) -- I usually point -S
  and -T to the same place: 
  	mkdir /tmp/mondo
	mondoarchive ... -S /tmp/mondo -T /tmp/mondo
  Wherever you point it there needs to be enough room to stage data
  the size of your media (650m).

I cannot comment on the -n ... parameters because I haven't done
backup to NFS.

No, absolutely not!  /dev/shm is a shared memory filesystem.

I realize that my remarks are not exactly a technical guidebook, but
perhaps they will help clarify things a bit.

Others can jump in here and point out any errors and/or oversights in
my remarks.   ...and I'm sure they will.  :-)

Re: Verification on Syntax Questions

Hello Andrew,

I agree with Bill.

And, concerning the scratchdir, I would use :
   -S /scratch -E /scratch

Victor

Re: Verification on Syntax Questions

Hi Andrew,

I agree with Bill.
Below is a sample of use with NFS:
# mondoarchive -O -n 10.58.117.171:/data -p <hostname+date> -N -d backup_200930/mondo -s 4380m -S /tmp/mondo/scratch -T /tmp/mondo/tmp -E "/udr /log"
WARNING: restore via PXE/NFS has been tested with late test version (ftp://ftp.mondorescue.org/test/...) because "nfspath" option (equivalent to '-d' mondoarchive) below is not supported yet by mondorescue 2.2.8 ! You may need to be patient for official release of it (check: http://trac.mondorescue.org/ticket/310)! But maybe if you let the archive in same dir between backup & restore mondorestore may be able to find it by itself... to be tested!
# cat /tftpboot/pxelinux.cfg/01-xx-xx-xx-xx-xx

Mondorestore missing CD-ROM

I've made a backup of my system to DVD using mondoarchive and all went well. As soon as I boot the DVD to try a restore it looks like the DVD is not mounted causing the restore to fail. As I'm not able to provide you with the logfiles I'll send you the errormessage that appears at the end of the boot sequence.

/init: line 721: ide-opt: not found

Does anyone have a clue?

Thanks in advance!

Re: Mondorestore missing CD-ROM

Hello Robin,
 
On which GNU/Linux distrib (and version) do you use Mondorescue ?
 
Which versions of Mondo and Mindi do you use ?
Example : rpm -qa | egrep 'mondo|mindi'
 
Do you backup and restore on the same machine ?
> ide-opt: not found
Before the backup, try to add ide-cd_mod in FORCE_MODS line of /usr/sbin/mindi script, on the machine on which you do the backup :
FORCE_MODS="ide-cd_mod"If the problem still appear, please email too these logs, from the machine on which you do the backup:/var/log/mondoarchive.log
/var/log/mindi.log

Re: Mondorestore missing CD-ROM

Hi Victor,

The FORCE_MODS entry did the trick for me! I'm using Mondo 2.2.8-6.1 and Mindi 2.0.2-3.1 on OpenSUSE 11.1 64-bit. Thanks again for the tip!

Kind regards,

Robin Meeuwsen

HELP... can't restore images on HP DL320 G5

Hi all,

looking desperately for help on this!
I think quite standard HW with HP Proliant DL320 G5 (especially with main mondo contributor by HP! ;-) )
but that one doesn't want to path the formatting of the partitions!

Joined is the corresponding mondoarchive.log (with debug level at 99).
I have took some snapshots of my screen
Also the monrestore.log which fails on formatting partitions

Maybe somebody can find what makes mondorestore not happy!?
Please note the following:
- there is a indication of slight partition size readjusment:
Changing /
Changing /dev/sda2 from 21001028 KB to 21001028 KB
Changing /dev/sda6 from 128162 KB to 128162 KB
final_size = 76319 MB
Mountlist adjusted to suit current hard drive(s)
- there is a mention of LVM when there is no LVM in place on source system
# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             4.8G  370M  4.2G   9% /
/dev/sda7              19G   57M   18G   1% /udr
/dev/sda5              15G  1.8G   12G  13% /usr
/dev/sda3              15G  383M   14G   3% /log
/dev/sda2              19G   65M   18G   1% /db
tmpfs                 506M     0  506M   0% /dev/shm
but
Preparing to format your disk(s)
Please wait. This may take a few minutes.
Configuring LVM
LVM initialized OK
                 I am now formatting your hard disk partitions.
- onboard RAID is mentioned

Apart from that I can't see what it is not happy

mondoarcive on kernel 2.6.30: unsupp initrd fs!

Hi,

With mondo-2.2.8-r2153 and mindi-2.0.6-r2153 I get 'UNSUPPORTED INITRD 
FS!' when I run mondoarchive with kernel 2.6.30 booted.

It makes no difference if I use my own compiled kernel or if I use Debian's.

Mindi gets to GetInitrdFilesystemToUse() and does its magic to find the 
fs of initrd in the kernel image and just cannot find it.

I tried mondoarcive with the 2.6.29 kernel booted and *that* runs just 
fine with the same mondo/mindi versions.

I also queried the Debian User List if anybody has tried mondoarchive 
with 2.6.30 booted and got zip for replies.

Is the 2.6.30 kernel that rare?

I enclose mondoarchive.log.sdb5.unsuppfs-hvw.gz of the run on my own 
compiled kernel,
mondoarchive.log.sdb5.2.6.29.gz of the successful run with the Debian 
2.6.29 kernel,
mindi.log.sdb5.unsuppfs.gz of the failed run on Debian's 2.6.30 kernel,
mindi.log.sdb5.unsuppfs-hvw.gz of the failed run with my own compiled 
2.6.30 kernel and,
mindi.log.sdb5.2.6.29.gz of the successful run with the 2.6.29 Debian 
kernel.

Hasn't anyone tried mondoarchive with the 2.6.30 kernel?

Second question: can anyone verbalize in detail what 
GetInitrdFilesystemToUse() actually does?

Thanks!

GetInitrdFilesystemToUse() looks for the phrase '<6>checking if image is 
initramfs...|<6>Unpacking initramfs...' to see if initrd uses an 
initramfs fs. *That* phrase is absent.

But when I change the phrase to '<6>Trying to unpack rootfs image as 
initramfs', which *is* present, mindi successfully terminates and 
mondoarchive completes.

Magic code alright, now see if the DVD will boot + restore... Stay tuned.
