CentOS 5 :: Cannot Log In After Restoring With Mondo Rescue
Nov 3, 2010
I install CentOS 5.5 from DVD, set root password and log in as root. Then I install Mondo Rescue backup solution, make a backup and restore from it. After that, the system boots just like before, but I cannot log in. When I enter the right password, a couple of lines of text flicks briefly on a screen, too fast to read and the it returns to the initial password prompt. When I enter wrong password, it says "Login incorrect".What am I doing wrong?
I am sending a message to mondo-devel mailing list, but I suspect the root of the problem lies in CentOS, or something that I do wrong with it?I have installed both i386 and x86_64 versions of CentOS 5.5 from DVD's, the problem is the same.I'm running this on a separate machine that I have just for experiments with CentOS and virtualization. I install CentOS with defaults except I uncheck "Desktop - Gnome" and check "Virtualization". I can reinstall if needed.

i can't use imondo restore anymore, due to upgtading to jessie, did aynone get to make it work with jessie. I love to use mondo restore because i can get hots backpus, and i can do partial restore so i can restore my full system preserving home foldest, other way i have to move my home folder, very much waste of time. I cant get installed it but it doesnt open up, it says mondo, mindi bad installed or something like that.

I created a CD image of my CentOS installation using mondo. When I booted from this CD and, in the restore process, selected an option to test the integrity of the image, it got to a certain point and said: Failure to execute /init. Kernel panic - not syncing: No init found. Try passing init= option to kernel.The instructions say the kernel may need to be recompiled with certain options.Does anyone know if the CentOS kernel needs to be recompiled for use with mondo? If so, with exactly what options?I'm using CentOS 5.5. dmesg: Linux version 2.6.18-194.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat4.1.2-48)) #1 SMP Fri Apr 2 14:58:14 EDT 2010.
Unfortunately I don't remember exactly what command I used to test the integrity of the mondo image, and http:[url]....the source of the instructions, is currently down.

We are doing some disaster recovery exercises with CentOS 5. One of the things we want to do is be able to restore to our old production server. However, after restoring the partitions the boot loader starts and then does nothing other than displaying the location of the kernel image at the top of the screen.
If I use the installation CD to boot and chroot into the system everything appears to work fine. I am not sure why the system isn't working right.

The last time I did a restore using cpio under CentOS 3.9 it took a very long time for me to find my seemingly correct command wasn't working and I ended up doing the work in Knoppix. This time I thought I'd run my command by wiser heads before the necessary tape turns up and I spend a lot of time finding my command doesn't work. cpio -i -mtvV --block-size=128 --no-absolute-filenames /var/log/maillog* < /dev/st0
Does this look right? The backup string is find / -path /mnt -prune -o -path /lost+found -prune -o -path /sys -prune -o -path /proc -prune -o -path /swapfile1 -prune -o -path /var/named/chroot/proc -prune -o -print | cpio -o -H crc --block-size=128 > /dev/st0
EDIT: I changed the restore string to cpio -i -mtvV --block-size=128 --no-absolute-filenames *var/log/maillog* < /dev/st0 EDIT2: Whoops, should be cpio -i -mvV --block-size=128 --no-absolute-filenames *var/log/maillog* < /dev/st0

I want to move on from dependable v8.04 to 10.04.I am not an expert user so decided to create a back up dvd of my old system using Mondo rescue. I came across the recommendation in [URL] "to adapt your /etc/apt/preferences file to avoid updates of mondo with apt-get with indeed older versions" because of problems using Mondo with 8.04. I have been unable to find the file /etc/apt/preferences in my system using file search or the Synaptic Manager. When I tried to create a file with this name the Synaptic Manager got up set.

i have a server which i have no physical access to, all i can do is boot in rescue mode from a live debian CD and i want to know of a way to install CentOS from iso image or maybe NFS? on that server using this debian live CD.
since it's live CD i can't mount the iso image and boot from it cos after reboot nothing will be preserved. so the case in breif is, i am booted form debian live cd and i want to install CentOS on the machine from that system using iso image

I am attempting to work with adding a new hard drive with a default logical volume setup. In order to complete the task, I am instructed to use a live CD to boot the system without mounting the drives using linux rescue. I am using CentOS-5.5-i386-LiveCD-Release2.iso
I have reviewed the centos documentation. When the live CD boots, it starts a count down to an automatic boot. I attempt to invoke the boot options as directed by hitting the tab and adding the words
linux rescue
At the end of the line and hit return to begin the booting process.
Unfortunately, the linux rescue boot option is ignored and the system mounts the hard drive. Additionally, I have checked the boot option several times by hitting the tab a second time and the option is not displayed.
In researching the issue, I inevitably get very similar instructions like:
Quote:The first centos CD or DVD has a rescue mode, just type on the boot screen: linux rescue

I am trying to build a server based on an ASUS P5BV-C, which has dual-Marvell 80856 Gig-E ethernet controllers.If I boot into rescue mode, using CentOS 5.3, x86_64, disc 1, I can start eth0, and it configures via dhcp. No problems.
If I boot the same disk with 'linux askmethod' and select http as the install method, it tries to start eth0, then times out trying to get dhcp. Checking tty3 (or 4, i forget) indicates the eth0 link is up, but no communication. Manual configuration doesn't work either.

Booting to CentOS 5.5 works and I am able to login with all my devices mounted. When I boot from the install DVD and type "linux rescue" I eventually get the message, after attempting to have one of the screens mount my partitions in read/write mode:
"An error occurred trying to mount some or all of your system. Some of it may be mounted under /mnt/sysimage." But nothing appears mounted under /mnt/sysimage. Should I try mounting my CentOS 5.5 partitions manually at this point ?

I installed ubuntu on a second hard drive.Nowhere did the fracken ubuntu installer ask my permission to over-write my mbr but that's exactly what it did.I'm booted off the rescue CD trying to restore the mbr to how centos left it (I'll add ubuntu to grub manually) but I can't boot into rescue.linux rescue results in a kernel panic suggesting I need the noapic argument. Makes sense, I needed that to install and need that in grub.linux rescue noapic boots into the installer, not rescue.How do I boot into rescue mode with the noapic kernel argument?

I have been reading about rescue CD's but haven't found out whether I can make one using my currently running Centos(centos-release-5-4.el5.centos.1 ).I tried to use a Centos cd we have here and it looks fine till it asks where the 'tree' structure is located, when I select cd it ejects it and asks the same question again. Do I need to build a rescue cd containing directory info of my specific system?This is related to wanting to fsck my file system.

give me the sequence for manually mounting devices in "rescue mode" ? When I try "linux rescue" from the install disk, it eventually fails to mount my partitions with a generalized failure message, which tells me nothing. I then try mounting them myself on /mnt/sysimage. I have separate root, boot, and home partititions. Is the sequence:
Mount root partition at /mnt/sysimage
chroot /mnt/sysimage
Mount boot partition at /boot
Mount home partition at /home
What about tmpfs, devpts, sysfs ? Do they need to be manually mounted also ? The 'mount' command does not show them as mounted after I do my chroot.

I save my whole system to a .tar.gz file weekly except for the /proc content. I have used this backup a few times to restore my system without issue.
Last time I restored, I discovered the following 2 issues I home somebody can explain:
#1: while extracting the .tar.gz using tar xzvf filename.tar.gz, I get the following error near the end of the restore process "tar: Incorrect Length". This error only occurs when I boot the system with the slackware 12.1 disc 1 CD. It does not occur if I try to restore from my working system, same file. Other than this, everything seems to be restored properly and the system boots up properly. I am just concerned by the meaning of this error.
#2: After restore, I do lilo -C /mnt/etc/lilo.conf to make sure the systems boots up properly. This works... however, I have discovered that just this won't make module autoloading work after the restore. When booting the restored system, no module autoload !
I have correct this by just entering setup when booted up using the slackware 12.1 disk 1 CD and going thru addswap, set target without format and the going thru the configuration menu and cancelling all question.
Why would modules not load automatically ?

all my test restores in vbox worked fine. i may use the backup as a second OS, so it works. but there i first deleted the old OS and than ran cp -a /media/backup_partition /media/restore_parititon.
yesterday i ran into trouble and had to restore my system.
mount /dev/sda1 /media/restore
mount /dev/sdb1 /media/backup
rsync -auv /media/backup/ /media/restore
that did work, but not so good. dpkg-errors, all non-repo-apps, like opera and some old thrash, were a mess. i had to reinstall them with dpkg to delete them. besides that the system is up and running, but it was a lot of work.

I'm really into desktop customization so today while i was changing a couple of things here, i did the stupidity of changing the recycle bin icon (right click on the icon> properties> basic tab). I obviously regreted it and now i'm trying desperatly to restore it to the default icon. I'm not a total noob when it comes to customization

The HD containing my main F14 install is suddenly failing with many unreadable blocks. So I booted a different F14 installation I have on another disk.
Then I run dump, for example, as following:
Code:
dump -0 -a -q -v -A sdb1_home.arc -f sdb1_home.dmp -L F14_sdb1_home /dev/sdb1
as, for what I can recall, I've often done to create full backups.
The problem is that running restore with this command:
Code:
restore -i -A sdb1_home.arc -f sdb1_home.dmp
(as, for whatI can...) and using the add and extract commands, only the directory are created. But files are listed using ls. If I add just a file, only dirname is extracted.

I currently backup my database using MySQL Administrator. I wanted to test out restoring the database, so on my test server I deleted the database and restored the .sql file to a new schema with the same name as the old. one. It appears to complete the process just fine. But I noticed that the number of rows for the restored database is slightly less than what was backed up.
Is this normal or should the numbers be exactly the same? It's only a difference of about 28 rows. I seem to be able to view the data just fine in the query tool.

had a lvm (non luks i suspect) home partition on my 11.04 install. I've since install opensue on the same laptop hoping that if i don't leave that partition alone during opensuse installation i would be able to mount and enter my key to access the data within...stupid me.... i formated my /boot and / partition, not my /home partition of 450gb. I'm now back on ubuntu 11.04 trying to get access to my data. i'v found the command "encryptfs-recover-private" but i only works on mounted partitons, i can't mount my encrypted partition because the system does not recongnize it. I've have to format it to mount it.
