General :: Not Clean Volume According To Tune2fs?

Jun 24, 2010

I did a tune2fs -l on some volumes of mine, and a few say "not clean" as the filesystem state. But how do I tell what's causing it to be not clean, or how severe it is, so i know how soon i need to schedule downtime to run a e2fsck on that volume?

General :: Safe To Tune2fs Mounted Volume To Prevent Disk Checks At Reboot?

May 12, 2010

I have some large volumes that I don't want to automatically be e2fsck'd when I reboot the server. Is it safe to change maximum mount count to -1 and check interval to 0 while a volume is mounted, or will that cause problems to the file system?

General :: Check JFS Disks (fsck.jfs) At Every Boots Using Tune2fs Like Tool?

May 15, 2010

Fstab has at the end some values: 0 1 for / or 0 2 for /home or others.

It is nice to set tune2fs -c 2 for disks that have to be reliable and increase the security of the data.

tune2fs is not working for JFS. How to make this check at every single boot of the Debian/ubuntu machine?

General :: Tune2fs Says Couldn't Find Valid Filesystem Superblock

May 12, 2010

I'm logged into a server through the CLI and did a df -T and confirmed all my volumes are ext3. but when I do a tune2fs -l /dev/sde it tells me

tune2fs 1.39 (29-May-2006)
tune2fs: Permission denied while trying to open /dev/sde
Couldn't find valid filesystem superblock.

I don't have root access on the server, but is that why it's complaining, or is my syntax incorrect?

Ubuntu :: Tune2fs Not Working For 2TB HDD?

Oct 18, 2010

I have a Western Digital 2TB HDD on Ubuntu 9.10. This is my secondary HDD which is used only for Storage of media files. I mount it as & when needed only to stream my media content. I have tried many times to use tune2fs to free up the extra space which has been reserved automatically by linux yet although it accepts the commands & doesnt give back any errors, when I run the df- h or du- h commands, linux has still reserved 200GB & I only have 1.8TB to use. This extremely annoying as Im quickly filling it up with about 400GB currently available for me, that could easily be 500GB.

My primary drive is a seperate HDD of 320GB Storage is /dev/sdb1 for which I mount it to a folder called 'media-centre'. Then after mounting, I run the command: tune2fs -m 0 /dev/sdb1 media-centre I takes the command with no problems, I run df -h, & no joy. I have read my books at home as well as google searches & forums. Am I missing something simple here, does this command work only with certain types of HDD's?

I posted on another forum & followed a post that said I should convert from ext3 to ext2 as the journal is the cause, I ran a tune2fs -O ^has_journal etx2 /dev/sdb1 (something like that) & checked /etc/fstab which did not reference my storage HDD.

General :: Move / Copy A Logical Volume From One Volume Group To Another?

Dec 1, 2010

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.

Ubuntu :: /etc/mtab And /proc/mounts Do Not Show Tune2fs Mount Option

May 23, 2011

I just discovered that you can automount an ext4 filesystem with acl enabled by running "tune2fs -o acl". (I knew about tune2fs but did not dare to use it until now). However, the acl mount option does not show up in /etc/mtab and /proc/mounts. Can I ignore this, or is there a way of telling the system about the actual mount options?

Edit: I can do "tune2fs -l <device> | grep acl | awk '{print $4}'" and if that isn't empty I can update /etc/mtab with "mount -f -o remount,acl <device>", but like the udev rule I previously messed with this seems lumberingly unelegant to me.

General :: Error - An Application Is Preventing The Volume "New Volume" From Being Unmounted

Feb 26, 2011

HP 210 Mini
Fedora 14 xfce

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?

General :: How To Clean Dish Space

Feb 4, 2009

I have a basic question regarding how to clean up linux disk space. I use "df" to check my disk and found out usage is 100%. SO I use "du -b | sort -r -n > tmp.txt" and found out that /var/spoon/clientmqueue/ has taken the biggest disk space. I deleted the file in that directory using "rm". But after that, I run "df" again, still got 100% usage.

Debian Multimedia :: How To Have Volume Buttons On Laptop Change 'pcm' Channel Volume Rather Than 'master'?

Jun 13, 2010

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 Multimedia :: Laptop Volume Buttons And GNOME Volume Are Not Synchronized

Feb 27, 2011

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.

Ubuntu :: Default Volume To 100% In Terminal With Gnome-volume-control-applet?

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.

Ubuntu Multimedia :: USB Soundcard Volume Controls With Laptop Volume Keys?

Oct 29, 2010

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.

Ubuntu Multimedia :: PCM Volume Not Affected By Master Volume Control With Alsa

Mar 7, 2011

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.

General :: Clean Makefiles After Calling ./configure

how can you remove all the makefiles and whatnot and basically restore the source package to its original form after you've called "./configure" or even "make" ?

for instance you changed the source code then you ran ./configure then make then make install ....etc you checked the software and it functioned as you expected it does , now you want to remove all the makefiles and all that other jizz that you don't need or want anymore in the source (obviously in order to package it for distribution)

what is the "standard" method for doing so?

General :: Clean /var Storage On Dedicated Server?

Feb 4, 2010

The /var directory is 97% full on my dedicated server:

I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).

I have Matrix control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.

I have Putty Access to root but do not know which command to use.

I found a few threads but the information is not clear to me as there seems to be an assumption of basic knowledge I don't yet have.

My linux/ubuntu support that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.

I have only a very basic understanding of command line but really need to get this sorted ASAP.

Ubuntu Multimedia :: Usb Headset - Cannot Regulate The Volume Of The Phones (output) Anymore With Gnome-volume-control

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:
