Fedora :: Clean / Tmp Safely At Shutdown

Jan 20, 2010

I have been using this tip at URL.. to delete the temporary files created in /tmp for quite a few Fedora versions. But, I just found out that it does not work in F12. Is there are reason why it doesn't work?

You can put this into /etc/rc.d/init.d/syslog into the "stop)" section. This will clean up /tmp at every shutdown and keep your disk clean. Please note that you should not run this command when X-Windows is running.

Debian :: Shutdown Fails On Clean Install

Nov 20, 2010

Did a clean minimal install of Testing in a Virtual Machine (VirtualBox).Login as root.Type "shutdown now".It starts shutting down, then says INIT: Sending processes the TERM signal Give root password for maintenance (or type Control-D to continue):If i press Control-D it goes back to a login prompt.Okay, i maybe missing a point since "shutdown -h now" gives the expected behaviour.Call me old fashioned but I think that a "shutdown now" should shutdown a system, and not effectively reboot the system. There is a reboot command for that.

Ubuntu Servers :: Run Fsck If Last Shutdown Wasn't Clean?

Jun 13, 2010

I have a file server that has a raid array with a jfs file system attached. Whenever there is a power cut (quite frequently in our house), and the server is not shutdown cleanly, then the raid array is not automatically mounted since ubuntu doesn't know if the journal is clean. I have to then manually run fsck and remount the partition by hand which is a bit annoying. Basically, does anybody know if fsck can be setto run if a non-clean shutdown has been detected, or failing that, on every boot?

Ubuntu :: 10.10 Clean Install - Sudden Shutdown / Power Off

Nov 9, 2010

I just did a clean reinstall of Ubuntu (10.04 --> 10.10). After the install, any time I do CPU intensive work, my PC is suddenly shutting down like it's overheating. Everything was working fine for months, and started having problems immediately after the reinstall. so this is not a problem with my hardware, and it's not a problem with my fans needing cleaning -- it's a problem with software. So please don't tell me "that sounds like overheating, clean your fans". Something is different in software-land between 10.04 and 10.10 that is causing this to happen.

I have checked my log files, and can't find anything related to overheating -- searches for things related to lm_sensors, "temp", and "thermal" are not turning up anything in the system logs (syslog, kern.log, or messages). I also looked at the logs around the times of the sudden shutdown, and couldn't find anything unusual. How can I diagnose this? I'd like to file a bug report, but since I can't find anything in the logs, I honestly have no idea how to go about providing useful information. Is there anything besides overheating that might be causing my laptop to suddenly shut off? (I am using a Gateway M-6888u laptop, btw)

Programming :: How To Properly Clean Up On Asynchronous Or Sudden Shutdown

Jun 6, 2010

I have an user space application that performs file I/O operations, when a SIGKILL is captured, some routines are done first to ensure that all I/O operations are completed before rebooting the application or system. My question is, this won't work if the power button is pressed or the power supply is disconnected, so there can be incomplete I/O operation or corrupted data written into the file, so is there a way to prevent data corruption or at least complete any ongoing operation when this scenario happens? Assuming there is at most 1 second before the power really went out, can I/O be still completed?' I'm running the application on a busybox 2.6.14 kernel on an embedded system board.

Ubuntu :: Is Alt+SysRq+o Shutdown 'clean' With Regard To Disk Buffers?

May 3, 2010

I've been having a bad problem with X freezing up (but not the whole system), and I hate continually performing unclean shutdowns with the power button.Will an Alt+SysRq+o shut down the system in a way that doesn't cause the loss of disk buffers? Obviously, whatever hasn't been saved to the buffer will be lost, but my concern extends to the buffers themselves.ext4 and autofsck make this less of an issue, but I hate the thought of unnecessary silent corruption until the freezing stops.

Fedora :: Difference Between Unmount And Safely Remove

Mar 25, 2010

I have an external HDD which I use under Fedora. After finishing with my work, I unmount all the mounted partitions of the external HDD & then proceed to switch it off. The HDD partitions are unmounted but they are still visible(but not mounted) under computer. The HDD still seems to spin. But when I click on "Safely Remove Drive" they disappear from Computer & also the HDD stops spinning albeit the switch on HDD being powered on. So what should I use "Unmount" or "Safely Remove". What is the difference between the two?

Fedora Installation :: Safely Removing Gnome

Jun 15, 2011

I've been using Gnome for several years and haven't had any real problems with it. Now, however, I find the descriptions of what Gnome 3 and the Gnome Shell quite unsettling. That is, the Gnome devs have added a number of things I don't want, removed things I do want and made it impossible to configure Gnome 3 to work anywhere near what I want without adding unsupported third-party extensions. (Note: this is neither a complaint nor a flame; it's just a statement of my personal taste and any attempts to argue about it will be ignored.)

Currently, I have installed XFCE and am very happy with it on my two F14 boxes. I know that if and when I move to F15 (or F16 if 15 continues to be as problematic as it is so far) the upgrade will include Gnome 3, even though I don't use it. I'd like, therefore, to remove it but without removing any bits and pieces of it that are needed by whatever programs I'm using. What's the safest way to do this?

Fedora Hardware :: Safely Remove Drive Freezes System?

Aug 26, 2011

Until a recent software update, I encountered no problems when 'Safely Removing' my external hard drive.

After the following update:

Aug 23 14:36:03 Installed: kernel-devel-
Aug 23 14:36:13 Installed: kernel-

The system freezes when I try to safely remove the drive. What I see is the blue screen with the Fedora logo, the caps lock key lights up and the system is totally frozen. Following is the information on my external drive gleamed from the messages log file when the device was mounted:

Aug 26 07:53:03 localhost kernel: [ 496.855476] usb 1-1.2: new high speed USB device using ehci_hcd and address 7

Fedora Installation :: Safely Remove Unsupported Packages After FC13 Upgrade?

Jun 2, 2010

I managed to successfully upgrade FC11 to FC13. While doing the post upgrade steps, I made a HUGE mistake. After identifying the unsupported packages, I used "yum remove package1 package2" command to remove the obsoleted ones without realizing the yum was also removing many FC13 packages! Here are the cmd sequence used:

# package-cleanup --orphans
# yum remove compat-db45-4.5.20-5.fc10.i386 flash-plugin- gnome-spell-1.0.8-5.fc9.i386 ifd-egate-0.05-21.i586


I simply typed Yes and left unattended for a few minutes after yum prompted there were # of packages to be removed as I blindly believed it would do the job. After returning to the computer, I found many installed icons were disappearing, the wireless suddenly turned off etc. I killed the yum process right away but it was too late.

-Is there anything I could do to undo the yum remove process?

-How to safely remove supported packages?

Server :: Shutdown The Nodes From The Master Terminal Using "shutdown -h Now" Get Shutdown?

Dec 10, 2010

I have installed a cluster computer with 10 nodes . The manufacturer is HP . All nodes and the master node have redhat enterprise linux installed in them . When I shutdown the nodes from the master terminal using "shutdown -h now" they get shutdown . But they dont get completely turned off . This issue bothers me when the power supply is given , all nodes boot up simultaneously generating a huge heat .

Thing to note : When we shutdown our PC they get completely turned off . When the power supply is given , a press on the Power On button is required to boot the system. But , why does it not happpen in the case of cluster? Is there any other way of completely turning off the nodes from the master terminal ?

Fedora :: Yum Cache So Big Even After It Clean All / Why Is So?

I have a small older HP OB6000 laptop with F14 on it and only 10GB of disk.

I've been weeding out a lot of packages I don't need on it to carve more user disk space.

One of the biggest disk consumers is /var/cache/yum. My problem is that even after a yum clean all it still consumes over 450MB.code...

Fedora Hardware :: Crashes On "Safely Remove" Of External HDD?

Jun 14, 2011

I'm running Fedora 15 GNOME3 on a Compaq Presario C700 laptop.

I have an external Transcend HDD. I have three partitions on it.

When I insert it, it's automatically detected and the partitions mounted and works perfectly well but when I "Safely Remove" the disk, Fedora freezes and hangs. The mouse is immobilized and none of the keyboard actions work. I can't even enter the Virtual Terminal. The music playing in the background loops a short 1 second buffer or so.

However, if I eject all the partitions by clicking on the eject button in Nautilus and then "Safely Remove Drive", it does not crash.

Fedora :: Clean Up Unused Packages?

Dec 6, 2009

I've been running fedora 12 for a few weeks now and I was wondering how to clean up all of my unused files. I have accumulated quite a bit of software in the form of updates and downloaded packages since starting and I can only assume these are going to continue to build. I have rpmorphan and it lists all of the programs I'm not using but I'm wary of it because it lists WINE as one I haven't used but I use it everyday to play a game. I'm afraid I'll erase something I need, but I'd like to keep my system as clean and slimmed down as possible.

Fedora :: Clean Up After Aborted Preupgrade?

Apr 27, 2010

I've just finished upgrading to f12 from f11 using the DVD ISO and all is well - I'm looking for a bit of guidance for a n00b on cleaning-up after an aborted preupgrade.A yum --enablerepo='*' clean all didn't clean-up as much as I'd hoped it would and neither did preupgrade-cli --clean - the latter of which reported that there was nothing to clean.I've upgraded all packages and removed orphans and just have the latest kernel installed.

Here's what I think I need to do:

# ls -l /boot | awk '{print $1 " " $8}'
-rw-r--r--. config-
-rw-r--r--. config-
drwxr-xr-x. efi
-rw-r--r--. elf-memtest86+-4.00


oh, now that i've posted this, i see a related post: Need to clean up failed preupgrade which confirms my thoughts.

Installation :: Clean Install Fedora 11 From USB?

Jan 7, 2010

The Fedora Core 8 which has been preloaded is certainly not up to scratch as all I want the laptop for is to play MP4 and AVI files. I have looked over all the threads on how to load fedora 11 (recommended version), and have gone to the Fedora site to download the files (32-bit was also recommended - running a i686 Intel Atom).

1. My issue is do I download the files onto CD/DVD, then copy those straight onto a USB and boot from there, or can I find another way to get it directly onto a USB stick without having to waste a CD/DVD?

2. There is also mention of a clean install and partitions across quite a few threads but I can't see how to do these and in what order, and are they necessary?

p.s there is no CD/DVD player on this machine so it can only be loaded from USB.

I can't remove any notifications package without removing a bunch of important software along with it. Also, F13 refuses to "Safely Remove" either of my external disks. I have to yank out the usb cord, touching wood each time.
