I am trying to figure out the "actual" disk size used by my system. When I run the "df -h" command, it outputs as below:
Windows Boot rescue disk from Linux??
location: linuxquestions.com - date: May 5, 2004
Forgive me if this is a stupid question...newbie here. I've been asked to make a Windows Boot Rescue Disk using my Linux distro (SuSE 8.2 Pro). This person says they don't have Linux on their computer - but I can use my Linux distro to make this rescue boot disk for him. Does anybody have any idea what I'm to do? Thanks in advance.
boot fails when booting from lvm partition
location: linuxquestions.com - date: March 4, 2006
I am trying to convert my root partition to use LVM. I have the LVM set up and the root has been copied to the partition, but when I try to boot with the root in the LVM partition I get a system panic saying it cant mount the root partition.
Running on Slackware V10.2
Kernel Version is 2.4.31
I get the messages
load the kernel from LVM /boot partition.
location: linuxquestions.com - date: November 14, 2011
I have /boot and /root that I have copy to a new one lvm volume.
I am try to boot my system through it but can't do that, it seems that all I need is to know what syntax to use on Grub2.
I have an uninteresting with lvm support in it, and I am still able to boot the system with the old partitions.
I didn't created a new grub.cfg file yet, since I want to test it without do it yet.
I need to know what syntax I need to use when I am try to boot from an lvm volume (that contain both /boot and /root as one partition).
I have Grub2 and Arch Linux if that helps.
Adding new disk to LVM + crypt
location: linux.com - date: April 21, 2011
I have currently disk setup like this:
sda2 was encrypted prior to lvm.
I need to increase lvm-root size with new disk, but I'm unsure how to do that properly. Suppose my new disk is sdb, I guess it's just something like
fdisk sdb, add new partition of type 8e
vgextend lvmgroup sdb1
lvextend -L 100%FREE lvm-root
Is this correct? And what about encryption, do I just encrypt sdb1 before doing the above, like I did with sda?
I'm just looking forward to do this without any dataloss from lvm-root.
Removing old kernels from /boot
location: linuxquestions.com - date: September 18, 2007
My boot partition is getting filled up after a number of kernel upgrades.
Is it okay to remove the old kernels from the /boot?
I see that the boot partition has config-..., initrd-..., System.map-..., and vmlinuz-...
Do I remove all 4 of them excluding the latest kernel?
Below is what my /boot looks like:
-rw-r--r-- 1 root root 49K Feb 24 2006 config-2.6.9-34.EL
-rw-r--r-- 1 root root 49K Feb 24 2006 config-2.6.9-34.ELsmp
-rw-r--r-- 1 root root 50K Feb 16 2007 config-2.6.9-42.0.10.EL
-rw-r--r-- 1 root root 49K Feb 16 2007 config-2.6.9-42.0.10.ELsmp
-rw-r--r-- 1 root root 50K Aug 17 2006 config-2.6.9-42.0.2.EL
-rw-r--r-- 1 root root 49K Aug 17 2006 config-2.6.9-42.0.2.ELsmp
-rw-r--r-- 1 root root 50K Sep 25 2006 config-2.6.9-42.0.3.EL
-rw-r--r-- 1 root root 49K Sep 25 2006 config-2.6.9-42.0.3.ELsmp
-rw-r--r-- 1 root root 50K Jan 23 2007 config-2.6.9-42.0.8.EL
-rw-r--r-- 1 root root 49K Jan 23 2007 config-2.6.9-42.0.8.ELsmp
Can I boot Super GRUB Disk from ISO ?
location: ubuntuforums.com - date: April 15, 2013
[COLOR=#FFFFFF ! important]2[/COLOR]Hi,
I want to try something; to speed up my Ubuntu boot time, I've turned off the GRUB menu, so that it would only display if I hold SHIFT during boot.
What's too bad is that doing this make it impossible to boot into Windows. It's apparently incompatible with OS_Prober.
Is there a workaround ?
I've thought about something. I know about the Super GRUB 2 Disk, which is basically a ISO that you can burn to a CD-ROM, and allow to choose GRUB entries from the CD (I use it to boot in Ubuntu when GRUB is wiped from the hard drive).
http://www.supergrubdisk.org/super-grub2-disk/[COLOR=#FFFFFF ! important]374[/COLOR]
I also know that you can boot a few ISOs from the GRUB menu. I've done it with GParted. Now, what I would like to do, is be able to boot this ISO from the GRUB menu. That way, I should be able to boot in Windows 7 using this ISO.
I've tried editing the GParted booting file from /etc/grub.d/40_custom:
exec tail -n
boot from lvm without initrd
location: linuxquestions.com - date: March 1, 2009
Installation is rh 5.2 using lvm. I'm able to boot using inintrd file
but without it get kernel panic not syncin vfs unable to mount root error.
I believe that I compiled the kernel with all the necessary optioins(not as modules)
so it's not a case of it not being able to undestand some filesystem. So my question is there
a way of booting from lvm without initrd file.
Removing administrative abilities from users
location: ubuntuforums.com - date: March 18, 2009
At my school we are starting up a test linux lab to see how it goes over with the students. We are trying three different versions, Ubunutu, Linux Mint, and Suse. The ubunutu install is under my control. I am attempting to create a student account with as few privileges as possible. Most of the main things, such as synaptic, were easy to lock out simply by unchecking all of the categories under the users and groups>configure>privileges menu. Yet still many things remain under the preferences and administrative panels that I would like to exclude, such as authorizations, network tools, system log, etc. In fact, what I would really love to do would be to remove the administrative menu from the main menu altogether in that account.
Thanks in advance for the help!
HOWTO download from FileSonic via a Python script
- date: March 9, 2011
Here's a Python script to make it easy to download files from Filesonic via the command line (i.e. no need for a GUI download manager). Just replace the userid, password, and dataURLs with the appropriate values and run the script. Note that the dataURLs can be multiple lines of URLs.
I just run the script as "python fs_get.py", but you might prefer to add the necessary bits to make it directly executable (add the usual "#!/usr/bin/python" at the start and the "#if __name__ == "__main__":" junk at the bottom).
Obviously there are lots of small things that could be done to make this nicer, so go wild and post your changes to this thread. For me, it works well enough as-is.
import cookielib, urllib2, urllib
import sys, os, traceback
userid = "[email protected]
password = "SEEEEEKRIT"
loginURL = "http://www.filesonic.com/user/login"
