I want to practice Veritas Volume Manager on my CentOS 5.5 x86_64 machine.
Thus, I have downloaded the appropriate package i.e. Storage Foundation and HA Solutions 5.1 SP1 for Linux Red Hat from here.
I believe this is the 60 day trial version. Does anyone know if it has some limitations also in this 60 day period ? Forgive my ignorance, I am new to Veritas.
I need to replace a disk from a veritas mirrored volume, I can not delete the disk from the diskgroup as the disk is using by other volumes in the same group. so, how can i remove the disk from my mirrored volume and can replace another disk.
View 1 Replies View RelatedI have a 2 node RH 5u4 64-bit. I have installed and configured the latest Veritas CFS (Cluster File System) which also uses Veritas Cluster Server. File system if VxFS. Storage is on EMC Symmetrix arrays with Veritas Mirroring between the arrays.We have noticed that running 'du -hs' on the shared directory/filesystem where it takes about 3 minutes on one node and 30 - 45 minutes on the other node.I've been running strace on 'du'.'du' runs an 'lstat' on each file (66,000+ files). On the slower node, the ave time spent in 'du' is about .001 seconds longer, which accounts for the 30-45 minutes. Also, the standard deviation is much larger, which means to me that the lstat times are all over the place!Another interesting thing is that iozone profiling shows that the i/o rates from both nodes are darn near identical, with no anomalies at various buffer & file sizes! And, iostat looks really good as does 'vxdmpadm iostat show
View 3 Replies View RelatedI am installing Debian for the very first time and having read websites similar to [url] I have come across parts of the installation which I do not understand.
For example, I have created logical volumes using the logical volume manager however am unclear what the message regarding writing changes to disk before configuring Logical Volume Manager means.
Once I have created the volume group, I am presented with a window that provides me with the ability to
Display configuration details
Create volume groups
Create logical volume
Delete logical volume
Extend volume group
Option 2 is pretty self-explanatory however am unsure whether it is advisable to segment directories between 2 or more volume groups. What benefits does it serve?
Option 5 provides me to extend a volume group however am unsure how this works?
Does it mean I can assign free space available one 1 physical drive to the existing volume group or does it mean I can assign free space available on a second phyical drive or does it mean both? How does it affect security, performance, etc?
Currently the only way I can see the logical volumes I have created by selection Option 4. Is there any other way? How do most people keep track of the logical volumes they have created e.g. checking off against a checklist, etc?
Next I have the ability to map the logical volumes to mount points however am confused what purpose the none mount point serves as I have the option to select it?
What are mount options for?
What do I use labels for?
What are reserved blocks for?
What does typical usage refer to?
How does the option to copy data from another partition work? What is it for?
Is there any way to have Volume Manager in systray without PA?
View 5 Replies View RelatedThe Volume control and network manager icons are not visible in the notification area..
I sure its has nothing to do with
Add to panel-->Notification area....beacuse the notification area is already there..
but the icons are not visible
the only way that I can make the visible is by typing code...
for volume control.. Only then they become visible in the notification area
Both, the network manager and volume control are mentioned in the "Start-up programs"
I've done an Upgrade from Lenny to Squeeze and I get these warning messages in syslog:

Maybe this is a reason, my Gnome Desktop from time to time is completely freezing.
I know how to manage them from a commandline but I was wondering if there are any graphical partition editors that understand and work with lvm2?
View 1 Replies View RelatedI'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.
View 2 Replies View RelatedDebian 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.
View 8 Replies View RelatedIs 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.
View 1 Replies View RelatedI'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?

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.

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 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.
View 2 Replies View RelatedI'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
View 3 Replies View RelatedI 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.
View 2 Replies View RelatedMy 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.
In Intrepid Ibex, I was using the left Super key as Volume Down and the right Super key as Volume Up, because it was just so convenient.
However when I go to the "Keyboard Shortcuts" window in Karmic, it doesn't let me assign the Super keys to anything. I mean like, I can use the Super Keys along with other keys, but not by themselves.
Is it somehow possible to use the Super keys for Volume Up and Volume Down in Karmic?
It seems that when I adjust the volume with the volume wheel on the side of my notebook, the OS messes up. Nothing is clickable, I cannot type anything, in order to get a working computer again I have to hard reset it.Why is this happening? I have never experienced this.

So why is there a change in the max of volume? I am a huge music person and that is the only thing holding me back from getting rid of gnome. I like how fresh and clean KDE is.

Volume up, volume down and mute keys on the keyboard don't control the volume any longer.They worked before. Hitting the keys brings up a progress bar widget with the volume level unchangeable, set at 0% (which is not accurate at all).It looks like the key mappings or key bindings are working, but there is a disconnect with actual functionality. The volume cannot be changed or muted anymore from the keyboard.
This worked just fine in KDE on Fedora 11 before upgrading KDE components yesterday with Yumex. I am now using KDE 4.3.2 I don't think that it's a coincidence that it stopped working after doing an update.
I updated the kernel and nVidia drivers too, but this problem exists when I went back and tested with the previous kernel, so I don't suspect the kernel upgrade. No info in Xorg.conf about the keyboard. Is there a setting that I am missing?
Sound works just fine. I can listen to whatever source I like.
