Resize a physical volume, will lvm freak out?
location: ubuntuforums.com - date: June 22, 2010
So I'm installing bsd in a virtual machine to play around with it, may install it to my machine if I have enough fun
This is my current partition layout.
Disk /dev/sda: 251.0 GB, 251000193024 bytes
255 heads, 63 sectors/track, 30515 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000e5e32
Device Boot Start End Blocks Id System
/dev/sda1 * 1 36 289138+ 83 Linux
/dev/sda2 37 30515 244822537 5 Extended
/dev/sda5 37 30515 244822536 8e Linux LVM
/dev/sda5 is the only physical volume in my volume group, will lvm freak out if I go resizing it so I can carve out some space for bsd.
Here is a screen shot of system-config-lvm if that is relevant.
12.04 Removing all games from default installation
location: linuxquestions.com - date: August 26, 2013
I know this has been raised/answered several times before, but the solutions I've found & tried have not worked for me completly.
I have Gnome panel and I can't work out how to remove:-
!. Applications > Games > "Aisleriot Solitaire"
2. The parent "Games" menu item itself.
All the other games have been deleted.
Right click on Applications allows editing the entries but not the removal of the "menu item" itself.
Removing hardcoded subs from .MKV video file
location: ubuntuforums.com - date: July 22, 2011
Is there a way to remove subs from an MKV (x264 if it matters) that seem to be hardcoded (VLC doesn't show any subtitles so I can't remove them). I don't mind re-encoding if necessary as long as the video quality remains the same and the video image isn't actually ripped out. Is it possible?
Removing KANJI characters from filenames batch mode
location: ubuntuforums.com - date: December 27, 2009
I'd like to find a batch renamer util that supports removing/replacing Japanese characters with English and/or , well- nothing.
I don't necessarily need a translator as part of the solution, what I want to do is rename files but not change/convert the contents.
I've been trying to find such a thing via search engines, both here in the forum and over the web, as well as via Synaptic- all to no avail.
Thx in advance,
[SOLVED] How to Rescue a VM from LVM storage pool?
location: linuxquestions.com - date: January 19, 2014
I'm looking to see if I can rescue a guest VM from a LVM Storage Pool.
I have a server with 2 disks. The CentOS 6.4 HOST OS was on /dev/sda and I had /dev/sdb dedicated to a LVM based storage pool where I had only one CentOS guest VM.
The HOST OS disk /dev/sda is broken. Doesn't appear to be recoverable and no backups (I know, that will be my next project after I get this all back up and running). All rescue tools I've tried result in many IO errors on sda.
The 2'nd disk sdb is intact but I don't know how to retrieve anything from it.
When I set this up, I followed the RedHat Virtualization Admin manual "12.1.4. LVM-based storage pools". So sdb had one physical volume and a volume group.
I inserted the good sdb disk into another/different healthy CentOS 6.5 server (where it shows up as /dev/sdc). lsblk shows this:
sdc 8:32 0 223.6G 0 disk
\_sdc1 8:33 0 223G 0 part
pvs and vgs don't show anythin
Problem removing preinstalled apps from Lubuntu desktop
location: ubuntuforums.com - date: February 28, 2013
I've just recently started using Lubuntu.
The first time I installed the 'minimal' system (from 'Minimal CD) and then installed the Lubuntu desktop on top. At that time I had no problem removing certain of the pre-installed applications (Pidgin, Penguin games etc) that I did not particularly need.
In the process of attempting to resize some partitions (evidently the wrong way) I messed up and decided to start over (new partition table) and re-install the full system.
This time I installed Lubuntu directly from the Lubuntu ISO 'Live' CD. All went fine except that now I find that whatever pre-installed application I mark for removal with Synaptic Package Manager (whether Removal or Complete Removal) it always lists the 'Lubuntu desktop' as one of the co-dependency packages that will be removed as well. So obviously, not wanting to lose the desktop, I have refrained.
I'm trying to think of what could have made the difference.
I don't know if it's relevant but when I first install
[SOLVED] Command to list the amount of unused space on a physical disk.
location: linuxquestions.com - date: July 9, 2013
Im new to Ubuntu or Linux and i'm looking for away to check the hard disk free space. I know about df -h, but that only shows me free space inside mounted partitions. I want to see unused disks space on the physical hard drive like /dev/sda not /dev/sda1
Getting this information in fdisk is hard because its only shows the blocks that are used.
If i a 500GB Disk and i create 1 partition that's 100GB in size, which command would i run so i can see the 400GB that are unused on the disk?
I'm a Windows SysAdmin that's trying to convert so please dont hate me.

Allowing SSH from Internet via router port forward.
location: linuxquestions.com - date: April 29, 2006
I'm trying to allow SSH from the internet on an OpenSuSE 10.x box that sits behind an router/firewall. The router/firewall has been configured to port forward port 22 to the static ip configured on the OpenSuSE box. Now I need to know how best to configure the firewall so that it doesn't drop packets from the Internet. Here's the problem. I've added SSH as an Allowed port to the Interface for the External Zone. However, the External Zone as far as OpenSuSE is concerned is my private network. As a result I can SSH into it while I'm on my network, but when I try to SSH into it from the Internet, it drops, blocks or other ways the packets (it seems the router/firewall is literally forwarding the packets, not NATing them in any way). So how do I get OpenSuSE 10.x to allow these Internet connections?
It would be bad to disable the firewall all together. How can I re-define the External Zone to be the Internet, without messing up the network setting on that machine? Any direction
