General :: Command To Add A Volume In An Existing LVM VolGroup?
May 23, 2011
I created LVM partition when I had access to GUI. Now the GUI has been removed and I need to create a new volume out of what was left untouched in LVM. I don't know any command to create a volume out of existing volume group.
pvdisplay shows as follows:
Code:
--- Physical volume ---
PV Name /dev/sda2
VG Name VolGroup00
PV Size 439.45 GB / not usable 16.42 MB
I'm trying opensuse 11.2 KDE out again after a bad experience last year. I'm installing it over Fedora 12 and when I try to install I get this error: Failure occured during following action: Deleting logical volume /dev/VolGroup/lv swap system error 4015 What does this mean? I've had other problems with with distro in the past but never this one. what is needed to enable the installer to install?
I have a system with a 2TB RAID level 1 installed (2 x 2TB drives, configured as RAID1 through the BIOS). I installed Centos 5.5 and it runs fine. I now added another 2x2TB drives and configured them as RAID1 through the BIOS.
How do I add this new RAID volume to the existing logical volume?
Could we create mirror of the existing volume in Linux. Is yes please let me know the procedure to create the mirror of existing Logical volume in Linux.
Im not getting able to neither add new users using command useradd nor delete existing users using command userdel. And even Im not getting able to login into any existing users except root. It was ok before. Im having this problem very recently on my linux server. Im using RHEL5.
If I start a script that is going to take a long time, I inevitably realize it after I've started the script, and wish I had a way of doing some kind of alert once it finishes.
So, for example, if I run:
really_long_script.sh
and press enter...how can I run another command once it finishes?
I'm rearranging a bunch of disks on my server at home and I find myself in the position of wanting to move a bunch of LVM logical volumes to another volume group. Is there a simple way to do this? I saw mention of a cplv command but this seems to be either old or not something that was ever available for linux.
I have an existing unix user that some how didnt make it into the copy over to our LDAP server. How do I add an existing unix user to an existing LDAP directory? Will ldapadd work? I was under the impression ldapadd required an ldif file to work properly.
I use F13. How can I control the volume of my desktop ssh'ing into it from my laptop?
I use the laptop like a remote control to control my desktop through vnc while watching movies, but changing volume through this setup is a bit too cumbersome and clumsy. I tried alsamixer but it behaves strangely and doesn't change volume.
I have kind of test partition, but I need lv_root on it. So I have:

I have inserted my handy drive. However, when I right click and select unmount I get the following message:
An application is preventing the volume "New Volume" from being unmounted
So I try from the command line:
umount /dev/sdb1
And I get the following message:
umount: /media/New Volume: device is busy.
All I have done is copied some files to my handy drive. So I am not sure what process is keeping my handy drive busy.Is there any command that I can use to see what process of anything else is using the handy drive?
I'm running squeeze (last updated today), and everything has been working great. There is only thing that would simplify my life minutely..Anybody know how can I have the volume buttons on my laptop change the "pcm" channel volume rather than "master"? If they could control pcm, then I could adjust the volume coming out of my headphones or my computer speaker (both controlled by pcm, but not master...seems strange to me) with just one click.I tried to find this info online, but all results seem to refer to an older version. The simple "click here, set this" solution no longer is possible.
Debian Squeeze 6.0.0 on a Thinkpad T43, sound volume is not synchronized between the laptop volume buttons and GNOME's Volume Applet. So if I turn the volume all the way down with the physical buttons, the volume applet may still indicate 75%.I did not have this problem in Debian Lenny. Pressing the volume buttons used to show a volume bar on the screen, as did pressing the mute button.
Is there a way to default volume to 100% in the terminal with gnome-volume-control-applet or any other program? I am setting up a dedicated Zsnes machine which boots into Fluxbox but the volume is muted by default. There isn't a man page for gnome-volume-control-applet.
When I log into Gnome the volume is set to 100%, but Fluxbox is always set to mute.
I've got my xubuntu 10.10 install just about perfect on a little acer aspire d250, apart from a small sound useability issue: In the interests of simplicity and resource usage I removed pulseaudio. After a bit of fiddling I got it so that my USB soundcard (ProDac) is recognized and automatically set as the default soundcard when plugged in. Any sound applications automatically use the USB sound if it present, no need to around with pulse. The only problem is that my netbook's volume control keys still only control the master volume of the inbuilt soundcard, and have no effect on the usb sound. Does anyone know of a way to change which sound device these keys actually effect? I'd like to write a little script so that when the usb device is detected the keys are remapped.
I'm running Kubuntu 10.10 32 bit on an old DFI KT600AL motherboard based system using the onboard VIA 3058 AC97 audio (because it supports front panel audio connections and none of the add-in PCI soundcards I have do). I have an old Gateway/STB TVPCI TV tuner card (mainly wanted the FM radio part to work) hooked up to the cd audio connector on the motherboard because the digital audio over the pci bus apparently isn't supported for this card (neither is the onboard analog mixer on the tv tuner card, I had to hack a CD-ROM audio cable and solder it to the audio outputs of the tv tuner module on the TV tuner card). When I use the master channel as the master channel (selected in Kmix) then as one would expect it affects the output volume of all other audio playing on the system except that which is being handled by the PCM channel. On Windows the PCM channel was also affected by the "Volume Control" slider such that ALL volume levels were reduced when moving the slider. I'm hoping someone can help me figure out how to make it work like this on Kubuntu.
First off I should warn you that I (like many users of older hardware that is not properly supported under PulseAudio) have uninstalled PulseAudio (because it's garbage) and am using Alsa to manage my audio hardware. I would think that there would be some way to do this using the 'amixer' application to add the PCM channel as a component of the 'Master' channel so that when the volume is turned down using the 'Master' channel control it will affect the PCM channel too (at least the output to the speaker jack, not necessarily the capture or mix volume though), but I'm not really any good at doing things from a terminal window and the options for the amixer command kind of confused me.
I used Ubuntu 10.10 (64 bit) on IMac i7. As far as, I remember, after installing Pulse-Audio Equalizer, for each restart of the system, after login screen, system sets volume to maximum value. What can I do?
since using 10.04 I have a big problem with my usb headset (freetalk everyman)
1. Problem: I cannot regulate the volume of the phones (output) anymore with gnome-volume-control. By default the volume is set to 100% which is way too loud. When I set it under 100% there is no sound at all. Values over 100% work.
2. Problem: The X server is freezing iregulary when I connect the headset and disconnect it, Magic SysRq works. I checked Xorg.0.log and found out that it recognizes the usb headset as keyboard:
I don't know much about lvm and I've managed to screw up a drive. I had a 500GB drive with FC14 on it and I wanted to copy over a load of data to my new 1TB that was replacing it. I set up my new install the same way as the old...including the same volume names (error number 1 I think) I successfully mounted the old/500GB drive (using vgscan and vgchange -a y etc.) using a laptop (running FC13) and an external hdd cradle. I could access the files I wanted but this wasn't the machine I wanted to copy them to (I was doing this while waiting for the install to finish on the new drive).
When I tried the same process on the new install I found that having two lvm with the same name meant I couldn't mount the external one. So I opened the disk utility (palimsest) and was going to change the name of the old volume group but it wouldn't let me do that. I then thought maybe I could get away with just changing the name of the partition where the files were and maybe I could add it to the mounted group or something so I changed it to lv_home2. This changed the name of my new/1TB lv_home to lv_home2 as well. So thinking that wasn't the answer I just changed the name of the new lv_home2 back to lv_home.
From that point on I haven't been able to see the old drives partitions (the new volume group still works so far). I has a physical volume but the volume group and volume names are gone from view. When I try to vgscan on my main computer or the laptop I had it working on earlier I get:
I'm using 10.04 now and it runs ok, except one strange thing in the Volume control applet. Sometimes, when I click on the volume slider, it moves up. Even if I try to slide it down, it moves up on every click. The same when I click left of it - it keeps moving up! This is very annoying at night when the music gets loud and wakes everybody. It happens with or without Compiz turned on
I am struggling with a problem with the volume control... when i try to adjust the volume with the sliding bar i can not do it. If i put the scrollbar to the 0 position, it is muted. when i move it to anywhere else, i get the full volume. From other programs like vlc, i can adjust the volume with no problem.
My volume control seems to have only three settings: TOO LOUD, VERY QUIET, OFF. If I adjust the Master volume slider from the Panel, only about the right 1/8th has any effect and if I slide it past about the 95% mark, I get no sound at all. At the far-right end of the volume control, I get total volume. It's basically like the slider only has any impact in the top 5% of it's space. Below 95% of the slide, there is zero volume.
It's so drastic, that one tap down of the volume button on my keyboard kills the sound (because it nudges the slider past that 95% mark). This happens in the Audio settings, etc., system-wide. If I adjust the volume for an individual app from within the app (MPlayer, for example) it behaves exactly as expected (that is, app volume works smoothly, it's just master volume that has this issue). I have run through most of the "obvious" things-- I'm wondering if I broke something by installing the extra KDE packages to get Amarok to work.
I try to write to a file "date > file" but Linux says 'cannot overwrite existing file'. I tried chmod 755 but still cannot write to the file. What should I do?
When I left work yesterday I left vim open with the files I was working on. I'm working from home today, so I VPN'ed in and when I go to edit those same files, I get the warning that there's another current vim session open with those files. I know I could just force logout my other user, but that would kill the existing vim session. I think my changes would all be saved in the .swp file. Instead, is it possible for me to take that existing vim session and open it with my second login? That way it would for sure preserve all my changes, and I wouldn't have to open all the same tabs again.
I run a command in a Linux terminal, the result was written to the desied folder. After I modified the command and rerun it. The old files are still there and not overwritten at all. Only it is successfull after I deleted the old files and run the command.
I recently ran across a client that wanted me to set up a new IDE Drive in his existing Red Hat Server. I reluctantly agreed to try. I am completely uneducated in Linux and could use some input. The server itself appears to be set up in text mode as all that I see is text after the initial boot up screen goes away. It, at present is set up in an old dell machine on a 3 Gig drive and all he wants is to be able to add a secondary drive to extend storage capacity. What do I need to do to prepare the drive and OS to accomplish the task? The secondary drive is 120 Gig. I reformatted the drive, as a fat 32 and installed it into the machine. The board sees it. The network does not
