CentOS 5 Hardware :: Server Reboots When UPS Unplugged?

Jun 3, 2011

I received a new Cyberpower CP1000PFCLCD UPS today. I let it charge for about 6 hours.My server is a former desktop PC with the following specs:MSI MotherboardAMD Athlon XP 2000+ CPU768 MB DDR RAMDual 80 GB HDD running RAID 1 (Disk Mirroring)After shutting the server, router, and backup drive down and plugging in the UPS, I did the UNPLUG test where you unplug the UPS to see if everything stays on.My Router and Backup disk both stayed powered on, but the Server immediately rebooted.Does anybody have any ideas how I can fix the server rebooting problem? It should be staying on just as everything else.

General :: Cousin Unplugged The Computer - Freezes And The Computer Reboots Over And Over

Apr 17, 2009

I boot linux from a usb drive so I can carry my distro wherever I go - I've been doing it for quite some time now and it's always worked wonderfully. Problem: This morning my little cousin unplugged the computer WHILE I was booting into linux. Power loss has happened before, but with no ill effects. This time however, it's decided it won't boot. The screen clears, and just as GRUB is about to load, it freezes and the computer reboots over and over.

I booted to a LiveCD of Ubuntu to try and fsck the drive, but it won't mount the volume. I've worked with this install so long, and have customized it so much I **really** don't want to do a reinstall.. What can I do?

CentOS 5 :: 5.5 System Randomly Reboots?

Sep 21, 2010

Running CentOS 5.5 on a Dell PowerEdge 710 with a mirrored RAID. System randomly reboots leading to MySQL table corruption as its not a graceful shutdown. Here is the output of the getinfo shell script [URL]. Some data has been obfuscated such as public ip addresses. Prior to posting this a full hardware diagnostic was run by the Data Centers support team which turned up nothing.

General :: Autostart An Application After CentOS 4.4 Reboots

Jan 28, 2010

I am fairly new to linux.We have a machine running CentOS 4.4 and sometimes the machine has to be rebooted. Each time after the reboot, I have to SSH in and manually restart one of our application. I have been reading about doing this online and I am a little confuse.Seems like there are multiple possibilities for starting things up. My finding suggest using the inittab file. Then my question is what runlevel do I pass in? Should I use runlevel 1, 2, 3, or 5? Once the runlevel is determine, then how should I name my startup script? I know to use "S" but what number should I give it? Or, another way to approach this is to put my autostart script in the /etc/rc.local file?

CentOS 5 :: CentoOS Xen Host Reboots When Guest Is Booting

Jan 5, 2011

I've found a workaround, but the workaround doesn't make any sense to me.I suspect I am running into a bug of some sort.I've tried to search for a solution, but the search terms are too broad and I can't seem to find anything useful.I have a CentOS 5.5 system that I've set up Virtualization on (presumably Xen, right?). I have a RHEL 5.4 Guest OS using "Full Virtualization" method.When I was installing the RHEL guest, the entire server rebooted just as the RHEL guest was booting for the first time.Thinking that odd, but coincidental, I just let the Host server reboot and then started up the RHEL Guest again.The reboot happened again and in the same spot! When I say the server rebooted, I mean black screen...pause...bios screen.I finally managed to get the RHEL Guest booted by removing the DVD that I had in the DVD drive and disconnecting it from the Guest OS in VMM. Very, very odd. I can reproduce this behavior by simply booting a Guest OS with a DVD in the drive (so far I've tried only RHEL guests).

The reboot happens at the same place in the Guest boot process. It's when RHEL starts the UDEV script. Actually, a few seconds after the RHEL system displays "Starting udev" message. I've looked in both the CentOS and RHEL messages log and found nothing.It's not a huge deal at this moment, but I will be sending these servers out into the field and I can't control what the end users of these systems put in the DVD drives.

CentOS 5 :: Fresh Install 5.6 Won't Boot - Reboots Instantly On Selecting From Grub

May 14, 2011

I just installed 5.6 using the x86_64 netinstall - all appeared to go well, albeit a little slowly. At the end of the install i rebooted the machine but CentOS won't load. If I select the CentOS option from grub (only other option is 'other') the machine instantly reboots.

Only options selected for install where 'server' and 'server gui'.

Editing the CentOS options shows the following but I've no idea whether this is correct or not (assume it is):

root (hd1,0)
kernel /vmlinuz-2.6.18-238.e15 ro root=/dev/VolGroup00/LogVol00 rhgb initrd /initrd-2.6.18-238.e15.img

CentOS 5 Networking :: Reboots Causes Unpredictable Enumeration Of Ethernet Drivers Causes Eth0 To Be Random?

Mar 20, 2009

I have several systems experiencing this issue, but the "worst case" system at the moment is a system where there are 2 dual-port PCI-X e1000 cards, and two on-board e1000e PCI-express card.What happens is maddening. If the /etc/sysconfig/hwconf is removed, and kudzu is not run, and the 6 interfaces each have a corresponding script:

/etc/sysconfig/network-script/ifcfg-eth0
/etc/sysconfig/network-script/ifcfg-eth1
/etc/sysconfig/network-script/ifcfg-eth2[code]...

Now what happens defies explanation. The only way I can be sure to make the e1000e first-listed-in-pci-order e1000e device always eth0 is to remake the initrd and add e1000e to the initrd.If I do not do that, eth0 might be the onboard night, it can also be the first port on either of the dual port cards.So eth0, eth2 and eth4 all take turns being eth0. This was not an issue in the EL-5.1 timeframe. This is certainly new to the EL-5.2 timeframe and thus far is not possible to control because the system does not load eth0's driver alias in order, and the enumeration of the PCI devices causes what seems to be random labeling of the first interface.

This is a particular problem in that identical hardware systems will come up with different eth0 interfaces , and on a single system, without the /etc/sysconfig/hwconf (which calls "eth0" something different from what was originally in the /etc/sysconfig/network-scripts/ifcfg-eth0 HWADDR directive).I need as little auto-magic as possible, I can live with PCI-bus order and driver load order is the order ethernet devices appear in, I cannot use the software in a state where what is "eth0" is randomly determined and the only way I can nail it down is to run kudzu, generate a hwconf AND brand the network interfaces in the network-scripts with HWADDR. I've been using EL since 6.2 and this is the first time I've ever encountered a situation where the enumeration rules (which are ancient at this point) over-ridden by something.

Version-Release number of selected component (if applicable): EL-5.2 series.The random enumeration of PCI devices and the subsequent assigning of eth0 to a random NIC is not on every reboot, and does not seem tied to a power off scenario vs a simple reset or warm reboot. Over the course of 0 reboots , eth0 should have moved between 2-3 times.Packages that seem relevant.

Debian Installation :: Unplugged HDD Now Cannot Start OS

Jun 8, 2010

I have some years experience of linux & programming, but I don't really know whats "under the hood" in a PC. I decided to learn. I have two hard drive disks in one of my computers, so I decided to see if I could run it with only one. I removed the voltage from one of the hard drive disks and when I booted, of course the cumputer gave me the message: "Disk failure, insert system disk and restart". When I reconnected the HDD in my computer and booted once again, I got the same message.

This brings me to my first question: Why can't I start my computer as usual after unplugging and replugging one of my two hard drive disks? All cables remains the same, what has changed? The first question remained unanswered and I tried to install a OS on one of the HDDs when the other was disconnected. This worked fine and I set up a windows/debian dual boot. Perfect! But after reconnecting the disconnected HDD I tried to do the same thing (so I would install a new version of the system I started out with, a windows/debian dual boot). I formatted and installed windows on one of my HDDs again. It was bootable.

When I installed debian and let the installer set up Grub, I got the message "Missing operating system" when booting. I tried to install only linux (without windows) and I reached the same resault: after unplugging and replugging one of my 2 HDDs I can no longer boot a debian operating system, though the installation runs without a problem. What has happened? What do I need to do to be able to install a working debian system on this computer? (installing windows works fine) Has the settings of my BIOS changed when I unplugged?

Ubuntu :: 9.10 Will Not Boot If External HDD Unplugged

Apr 29, 2010

When my Western Digital MyBook is plugged into my desktop machine via usb everything works fine. The computer boots up normally to the dual boot screen, and all OS options will boot up normally. However, if I unplug the external hdd (whether that be when the computer is off, or I unmount it and then restart) before I get to the dual boot screen I get an error message informing me that I have incorrect boot media, and to insert and hit any key. Some background: I have checked the bios and it is set up to boot from the internal sata hdd as the first boot device, and there are no usb boot devices defined. Prior to making this a dual boot machine, it ran windows only, and had no issues booting when the external hdd was unplugged.

Ubuntu :: 10.10 Will Not Boot If Laptop Unplugged

Feb 18, 2011

I have got rid of windows 7 of my laptop and installed Ubuntu 10.10. So for the past week or so have done a lot o testing and stuff. Laptop I have is hp pavilion tx 2000 model tx 2130ea. Problem I have is laptop wont boot when unplugged but boots when plugged in. When it starts up you can hear the logo music but screen remains black. Now I have found what the problem is after hours of fault finding. Ubuntu detects the additional drivers to download wireless driver etc., and a couple of nvidia 2d/3d drivers so its when one these nvidia drivers are installed is what causes the problem when booting up unplugged. No problem when plugged in. At the moment I just have not installed these nividia drivers and all is good. Graphics Card Nvidia Geforce Go 6150.

Ubuntu :: BIOS Not Found - External HD Unplugged

May 26, 2010

So basically, as rookie as it sounds, I spent about 3 days trying to figure out why my computer wouldn't boot (BIOS not found, then it ran grub rescue) until I saw that my external hard drive (which evidently somehow has some file on) was unplugged. I am running windows and ubuntu 10.4 on partitions on my computer's internal 120gb drive. The problem I have is that during these 3 days, I re-installed ubuntu on the drive from the CD- so I think I have 3 partitions, even though the 3rd does not show up as an option to boot into from startup.

What it does show though, is on my desktop I have 2 mounted drives:
One 52gb one that has my Windows files in it, and one 44gb one that has ubuntu files in it, but NOT the ones I use- this is the rogue copy I installed by "accident". I checked this by looking through the contents and it was all minimal (nothing in home folder).
How do I "remove" this partition safely, and return to having just a windows an ubuntu partition?

Networking :: Won't Boot When Ether Cable Unplugged Or In New LAN?

I'm trying to boot and connect to my home internet provider.With or without ethernet cable connected, the boot process seems to timeout on a number of steps (system logger, NFS Statd, automount5) and eventually get's stuck in NFS quotas.I started looking at /etc (in single user mode) and of course there are a bunch of files (hosts, resolv.conf, etc) with hard IPs, domains, etc.My questions are:- how hard is to change network setting to use soft IP and be able to connect to my provider

Software :: Can't Unmount After Unplugged Usb Drive On Accident

Oct 26, 2010

I accidentally unplugged my usb drive before unmounting it. In windows this is no big deal, so I'm used to that. However, I'm finding that in Kubuntu 10.04 this is a big deal. Now I can't mount any other drives unless I use the command line. Also, I can't unmount anything, even if I mount it on the command line.

What do i do? I know a reboot will fix this, but if it happens again i will be right back at this point. It should not take a full reboot just to unmount a drive. I have tried umount -l and umount -f and the terminal window just hangs.

Fedora Hardware :: AC Adaptor Alternately Plugged In And Unplugged?

Dec 30, 2010

I am using a Laptop with Fedora 12 and got a recent issue with the power management. I am not sure if this issue is Fedora-related, thereforeI have a (relatively) new main battery in my laptop and a (relatively) new Ac adapter (both not older than 6 months). Besides, a second battery is installed. Recently, I took out the second battery because I needed to use the CD rom drive. Then I put back the second battery (when the laptop was off, of corse).

After I switched the Laptop on again, everything works fine unless the laptop is thinking I am unplugging and plugging in the AC adapter every 3 seconds or so. I can see that behavior when clicking on the battery symbol, as the following terms change every few seconds:AC Adapter: Plugged inAC Adapter: Not Plugged inAlso I notice that the batteries are much slower charged than before when the laptop is operating, and even slower or halting when the laptop is powered off.

Ubuntu Networking :: PC Runs Slow If Network Unplugged?

Dec 16, 2010

I've been asked to look at a system which is running slowly. It's running hardy on an intel Q9400 quad core CPU system which should be a pretty fast machine.

The most obvious symptom of this problem is that the terminal takes about 10 seconds to open instead of the usual fraction of a second.

What I've discovered so far is that the system has 2 network ports one configured to access the LAN and the other to connect directly to another piece of hardware using a different subnet. If the LAN is not connected the system runs slowly and if it is connected it runs at normal speed. It also makes no difference whether or not the second network port is connected.

I've looked at the system monitor and can see no abnormal network traffic or processes using a lot of CPU resources.

Ubuntu :: Automatically Unmount Encrypted USB Flash Drive When Device Is Unplugged?

Apr 21, 2010

I formatted the USB flash drive using Karmic's Format Disk utility (right-click on a volume, select "Format..."), and selected "Encrypted, compatible with Linux (FAT)" from the "Type" drop-down menu.It mounts correctly when I plug it in, and I can access the files just fine.When I unplug the Flash drive without using the 'Safely Remove Drive' option, the icon on my desktop changes its name to '2.0 GB Encrypted', instead of disappearing and unmounting like my unencrypted Flash drives do.

I would like to have encrypted Flash drive treated in the same way as my unencrypted Flash drives, which disappear and unmount when unplugged, even if the 'Remove Safely' menu option isn't used. What can I do to accomplish this?NOTES:When I plug the encrypted Flash drive in, the following line shows up in the output of 'mount'. 'secure' is the name I gave the disk during the format process:

Code:
/dev/mapper/devkit-disks-luks-uuid-302db16c-c6e2-4dd9-a259-436437c76475-uid1005 on /media/secure type vfat

Software :: Horelease /dev Entry Of Unplugged Storage Device While A Program Has A File Open

I plug a USB device, it gets a /dev entry, e.g. sdf, i mount its filesystem, then some program opens a file on this filesystem. I unplug this device, its /dev entry disappears, but if i replug this device again, it gets another name - sdg.

How can i force the program to close the file so the filesystem is ready to be unmounted without using "lazy unmount" to release the device name, BUT so that the program doesn't crash after trying to make I/O to this file, and, of course, without having to kill the program?
