hello dear linux-experts,

How to access failsafe mode from bootloader in openseuse 13.2

i need to do some erasings in the log-files since the system does not start correcly. #

Question i need to access the comand line - how to do this!?

btw: need to erase the logfiles:

  1. rm -rf /var/log/*
  2. dmesg -c
  3. reboot Since this works,

this would be possible too. - if logrotate is installed…

sudo /etc/cron.daily/logrotate

  • therefore i am in need to get to the commandline

note: the systems does not start regularily

hello dear linux-experts,

again me - to give you the full and complete story:

i get the following error:

loading linux 3.12.53-40-desktop
error _ file Boot/vmzlinuz-3.12.53-40-desktop not found
loading initial ramdisk
error you need to load the kernel first
press any key to continue

if i press a key i get the following page -as an overview:

opensuse 12.3 with linux 3.12
opensuse 12.3 with linux 3.12
opensuse 12.3 with linux 3.11
opensuse 12.3 with linux 3.11

but no entry helps here - i am lost since this is a loop!!!

well i think i need to have the filesave mode.

well i am trying to find out why - i have had the same issues months ago see some interesting insights into the system - see here …

note, this sheds a light on the system - and now it is brocken again

the last time i ve had issues with

/var/log files

According to the link above i thought that the deletion of the the files was necessary.

what did i do; i have deleted the files - that are older first.

note; THIS WAS NOT A FRESH INSTALLTION

What helped the last time;: i have had to erase the logfiles:

  1. rm -rf /var/log/*
  2. dmesg -c
  3. reboot Since this works,

this would be possible too. - if logrotate is installed…

sudo /etc/cron.daily/logrotate

but now - i have some more issues;

when i try to get into grub (with F4 while the machine is starting) i get the following

invalid Recovery AreaGRUB loading.
Wellcome to GRUB!

error: unknown fileysystem.
Entering rescue mode…

grub rescue

what should i do now?

love to hear from you

well - this seems to be a filesystem corruption - or what would you say!?

btw. i cannot do this with GPARTED too !? can i -
i guess that Gparted is a bit easier to handle

and with gparted i also can work with comand-line , can t i?!

love to hear from you…

you should never manually delete those files, the OS handle’s this, leave those files alone
from what I understood your kernel is missing you probably deleted something
as you have ext4 you need a reinstall, you can select upgrade from the 13.2 install disk.
before reinstalling backup your files, you can use the 13.2 live image
http://download.opensuse.org/distribution/13.2/iso/openSUSE-13.2-KDE-Live-x86_64.iso
you can reinstall 13.2 from the live disk but beware do not to format your /home partition

hello dear I_A

many many thanks for the quick reply and the great tips. Youre very supportive.

understood.

one question though: can i do some cleanings of the drive with Gparted.

guess that this (live-CD) is a bit easier to handle than the OpenSuse Live-ISO.
note: do i can log in with the Opensuse Live DVD in the same way as i do with the installed system too?
and above all: is it very difficult to mound all the drives (and partitions) that i have to work on.

with knoppix i remember i had to mount the differnt drives.

so this musings lead me to the question: can i do some cleanings of the drive with Gparted?

love to hear from you

the link was to a live cd, it’s a opensuse 13.2 live kde, you do non’t need gparted as the live cd can reformat your system
As far as II know there is no user or root password on the live cd, if your /home partition was encrypted you might have issues,
My idea was you boot from the live cd, copy/backup your files to a usb drive or another disk/partition and reinstall opensuse 13.2 from the live image

a bit of a warning 13.2 will die in a few months but there is no leap live image, if there are no important files on your disk maybe a move to leap might be a better idea

  1. What is the file system you’re using for your root partition, BTRFS or EXT?

  2. Are you running openSUSE 13.2 or 12.3? Your original post suggests you <might> be running 12.3 which is extremely old and very different than 13.2 (and other currently supported openSUSE).

  3. You suggest that your system does not boot “regularly.” Can your system boot at all sometimes?

love to hear from you

btw: if i take the live-DVD - the openSuse 13.2: can i access all the data in order to save it?

do i need some root or some other password / user credentials?

i want to save all the data.

btw: at the moment i cannot see any GRUB> Rescue any more
i have done some cleanings with Gparted - doing so - i guess that i have erased some thing

what i can do:
starting a knoppix and having a look at the various partitions
seeing the temp-directory and erasing some files…

hope that i can do all i need to do… i am a bit frightend that i loose all

see the full system - screenshots i took some weeks ago…

sda7 is readable - with / under knoppix. i can save this
sda1 and sda 2 - have been lvm partitions - i have erased with gparted
sda5 is swap-partition - this does have to be saved
remaining - sda7 and sda6 - those needs to be saved.

what do you say. ?
