not able of booting into rescue mode

[Angelo Moreschini]

Hi,

I'm not able of booting fedora 20 into rescue mode.

 In the manuals is wrote:

Once you have booted, using one of the described methods, (booting  from a
boot CD-ROM or DVD, ...,  ...)

add the keyword rescue as a kernel parameter.

For example, for an x86 system, type the following command at the
installation boot prompt:

linux  rescue

etc ...............


*but I can not see any prompt* where I can type
that command.


When I boot from my disk of installation  (fedora live 20)
I get (only) the following menu:

   -

   start fedora live in basic graphic mode;
   - test this media and start fedora live
   - run a boot memory test
   - boot from local drive
   - return to main menu

( I opt for the first option (of course) and so by the installation of the
OS)

nothing to do with a recovery procedure .....

 What am I doing wrong ?

Regards

Thank you

Angelo

Every Linux boot
media can display the prompt, but the commands available have to be
included on the media itself. 
 The rescue commands are not provided by
Fedora LiveCDs. So you need to download a non-liveCD Fedora installation
media, boot from it and then use the prompt.

Yes. Except, loaded rather than installed; loaded suggests read from
disk into memory, installed suggests extracted from package and saved
to a drive.

syslinux - isolinux - extlinux all typically look to a configuration
file for this. The configuration file includes drawing a menu, what
the menu options are, and their underlying commands. Or you can do it
from the boot: prompt. All of this is fairly well detailed in syslinux
documentation.

Well if you're booting from other media, then first you need to
identify the partition that contains the file system volume you want
to repair. Some combination of:

parted -l
lsblk
blkid

Should hopefully give you a hint what /dev/sdXY is that partition. And
then it depends on what filesystem it is what command you should use:
e2fsck, xfs_repair, btrfs check, and so on. fsck itself will detect
the file system and run fsck.<foo> but off hand the only three
filesystems this works on are ext234, fat, and ntfs.

But like I mentioned in another thread, it's easier to just use
rd.break=cmdline as a kernel parameter from the boot menu of the
installed system (no rescue media), and then just do file system
check/repair from there. Both the hostonly (default) and nohostonly
initramfs contain disk repair tools. So you don't need a successfully
mounted root to have access to these tools. And further, except for
FAT, it's not that common to need fsck. All the other filesystems
listed have journals and usually journal playback is sufficient to
make the file system consistent again. The whole idea of journals is
to obviate the need for (most, not all) filesystem checks or repairs.
So if you have to do it often it'l make me think something else is
wrong that's causing file system corruption to happen.

No. Syslinux is a bootloader. Its job is to find, load, and execute a
kernel. There are derivatives isolinux, extlinux, pxelinux.

I'm uncertain what you mean by "virtual kernel" but if you mean a
virtual machine, you wouldn't use a virtual machine to repair the file
system on the drive. If you need to fix virtual machine image
filesystems, then you can use guestfish to access the image's
filesystem to run fsck. Guestfish is in libguestfs-tools package.

I  learned, just now, something about the use of SYSLINUX.
That it is interesting, and I would like to know if the utilities of
SystemRescueCD are equivalent to use the SYSLINUX procedure...
(if they also allow to intervene in the same way to repair to an HD permanently
installed on the computer - Perhaps you don't know this very well... -you
said it- ).

And...
When we get (in some way) a working virtual kernel working on the RAM, how
we can access to the real file system (that is stored on the HD of the
computer)
in order to intervene at its repair?

----

I am not also sure  about your last answer:
You say that I can type a kernel file name at the prompt boot, after I
clicked the key "escape"...
But, ...how it  continue  this work, after?
...what I can (...at the last...) gain, performing this procedure,  ??
... I am afraid do do it really.. and don't understand ...

Bad advice and wrong.
All the OP has to do is hit the escape key to get the boot: command prompt
at which s/he can type linux rescue

I Chris,

you were really good in your explanation which helped me a lot to understand

Angelo, 

Working with CD or DVD images is basically the same. You
download the install DVD from the same place you download the LiveCD and
burn it the same way. Of course you need a DVD drive with write
capability, but I hope your computer is not so old to have only a CD
drive. 

When you enter fedoraproject.org, clik on the "Server" link,
then "Download now". It provides a DVD install iso image, while the
"Workstaion" link on the home page provides a LiveCD image. Also note
the "Other downloads" on the same page: it provides the netinst isos
someone else talked about. Those are much smaller than the DVD images
but provides the rescue option if that's all you need. 

If you need an
older Fedora release, the lastest Fedora Project web site doesn't
provide easy links anymore. But you can copy any of the download links
for the latest release and strip from the file name until the release
number, for example:


http://download.fedoraproject.org/pub/fedora/linux/releases/21/Server/x86...


becomes


http://download.fedoraproject.org/pub/fedora/linux/releases/ 

Then
you can click on the release number you want and browse until you find
the install or netinst image you want. For example, if you need Fedora
18, you'd click 18/Fedora/x86_64/iso/ to get the DVD and netinst iso
images. 

Please be aware some mirrors won't provide all releases. In
this case, start over from until you get directed to a
http://download.fedoraproject.org/pub/fedora/linux/releases/ mirrior
that has the release you want. 

If you need a relase that's too old and
most mirrors have already deleted it, go to:


http://archives.fedoraproject.org/pub/archive/fedora/

Ok  now I understand better...
So syslinux need to know what is the kernel that have to be installed...

<  I'm uncertain what you mean by "virtual kernel"

I mean the *kernel that is running on the computer* (I used 'virtual'
inappropriately,
because it is loaded from a special support - the CD used for the procedure
of  restoring - and not is loaded from the HD that is installed on the
computer).


What abut to purpose (-the finality-) of the procedure that begin when I click
the key "escape"...
When I am using the CD with the iso image of Fedora live ?
What I gain at the last of this procedure ...?

Any problem is a very long list. I've never used sysresccd. I think
the goals of that project are quite purposeful, but also challenging,
depending on the problem.

As a very narrow scope example, its current version contains
btrfs-progs 3.17.1. But Fedora has had a 3.18.x version for nearly a
month, including 3.18.1 in stable now, and 3.18.2 (current to
upstream) since 3 days ago. So getting new things in Fedora itself are
pretty easy. I tend to use something like the Fedora live security
spin, and yum or dnf upgrade or install whatever tool I need.

I don't understand the question. I'm not sure what you want to fix,
and any problem is simply too long a list to answer.

Thank you to all of you,

I learned many things that I yet did not know ...
And also I have yet to explore issues ...

Just I would still ask :

   - we can get a linux kernel using SystemRescueCD (
   http://www.sysresccd.org/SystemRescueCd_Homepage) it is possible to fix
   any "rescue problem" in this environment? And, if it is possible to do,
   how we can achieve this purpose?


   - what we can do with the prompt (boot : ) that comes when we type "
   escape" from the "iso installation disc CD" ?

There's no rescue option on the Live image AFAICS; typing rescue at
the "boot: " prompt returns an error.

And IINM adding rescue to the kernel cmdline is the equivalent to
using "rescue" the "boot: " prompt on the netinstall or the DVD
images.

FYI it's not linux rescue. It's just rescue. Add one word at the end
of the boot parameter line.

On BIOS systems, the media uses isolinux, so to edit the boot
parameter you use arrow keys to choose the boot option you want, hit
tab and the cursor should already be at the end of that line, so just
type rescue and then press enter.

On UEFI systems, the media uses GRUB2, so to edit the boot parameter
you need to use arrow keys to pick the boot option you want, hit the
letter e to edit that entry, and then use arrows to find the line
starting with linuxefi and use arrow keys to (laboriously) get to the
end of that line where you see rhgb quiet and add the word rescue.
Then you need to hit either control-x or F10 or Fn+F10 depending on
how your keyboard, firmware, and GRUB negotiate such things.

(On my Mac, it's always Fn+F10, nothing else works. On a new Dell,
it's always control-x, nothing else works. Joy.)

Angelo, the live media images do NOT have the "rescue" option. You
first must download the netinst iso. One location you can get it from
is:

http://download.fedoraproject.org/pub/fedora/linux/releases/21/Server/x86...

Boot from that image and you should be able to get to the boot prompt
and enter:

thank you for answering me..

Yes (for installing Fedora) I am using a live CD..; and I know that it is
also a possibility to use DVD iso (about that I have to learn).

However  I was able to get the prompt pressing "Escape" [?]

Anyway I still  not was been able to enter in recovery mode from the prompt,
because both the command: "linux rescue" and "init.rescue"  were not
recognized by the interpreter.

Always I got the message :
° could not find kernel image °

Could you tell me what is the command to enter in recovery mode, from the
prompt,  with Fedora 20, please ?

Where did you read that?

This is the F20 installation guide:
https://docs.fedoraproject.org/en-US/Fedora/20/html/Installation_Guide/se...

The rescue option is only available in the netinstall and the DVD
images, but not the Live images AFAIK.

Hi, Angelo,

Did you tried pressing "Escape" from that menu to reach the prompt ?
