I need to force a shutdown. It seems I have lost an array and now the system refuses to shutdown.
Code:
echo o > /proc/sysrq-trigger
gives the warning but no dice.
reboot -f = nothing.
Recently I installed vncserver (tigervnc) on my desktop. Ever since my computer refuses to shutdown normally. At shutdown the following message pops up: Quote: System policy prevents stopping the system when other users are logged in Then I have to enter the root password to shutdown. If I stop vncserver before, the computer shuts down normally.

You do not appear to be using the NVIDIA X driver. edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.
Last night did a shutdown -h +120 which I have done regularly without problems. Only difference was there were some updates to go on which I said Restart later to.
Now my NVIDIA driver is screwed - as in I can't get my dual screens working. I have tried: sudo nvidia-config as suggested but not sure what it means by restart X server - PC restarted? No difference.
I just restarted my server (Ubuntu 9.04 server, running on ESXi 4.0) and while copying files onto the server using samba I got strange problems and the connection was lost. When I rebooted the total system, so ESXi as well as Ubuntu Server I did find problems on my RAID disk.
The directory, where the new files were added I have a lot of files, but a lot of them do not have any info except their name:

Both mirror disks are still functioning and I can still add/delete files, from the server, from other LINUX systems and from other Windows systems via samba.
I did make a full backup on a different server.
I'm trying to reboot the server (shutdown -r now).But it seems like nothing happened.
When I try "shutdown -c", the system prompts "shutdown: cannot find pid of running shutdown."
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 ?
I am a new to linux. I recently purchased a used dell d820. It has 2 gigabites of ram, and has centrino duo. The hard drive is 80 gigabites. I used boot and nuke to erase windows xp, in order to install linux. (I was quite unhappy with the screen, codec, and other problems I was having with windows.)
However, each time I try to install Fedora, or any other version of linux to the hard drive, the computer shuts down ENTIRELY.
Is there a way to fix this? I seems like my machine just doesn't like linux?
So I've recently installed Kubuntu 10.04, and after the first and second runs, the system refuses to connect to the network/internet. I'm not sure why this is, or how to fix it. It shows up in ifconfig, but other than that I'm at a loss. The Knetworkmanager applet says "Disabled" when I hover over it, and no connection can be made to the internet (apt, Firefox). I'm running x86, with a Biostar T5XE mainboard (Realtek RTL8168D/8111D network chipset). The logs don't seem to indicate a problem, though I could be wrong. The connection is known good: it connected before, but it won't now.

Because it only has 256 MB RAM, I used a minimal CD and the installed lxde as the GUI.Today I was working on it and installed the latest updates and Openoffice-Writer. After rebooting, the shutdown button only gives me Hibernate, Log Out and Cancel. I lost Shut Down and Restart. Searching w/Google shows solutions for other distros such as Arch and Mint, but none that worked for Ubuntu w/LXDE. Either the files to edit don't exist, the groups don't exist (one site said to add the user to the "power" group, no such thing in 'buntu) or the options don't exist (such as System->Administration, which isn't in the menu at all).
HAL and dbus are running, which was the other thing some sites mentioned.So, how do I get the shutdown and restart buttons back? The people that will be getting this machine aren't going to know how to go to a terminal and type "sudo shutdown -h now" everytime they want to shut down.I know the buttons existed before installing the latest updates.

I have 3 different systems all running the same OS and KDE versions and it is happening on all 3 systems. All systems have the "Offer Shutdown Options" selected in Session Manager. I have even turned this option off, rebooted, and then back on to try to jumpstart it but that did not work.
Additionally, I have tried deleting the contents of the /tmp directory while in single-user mode and also the .kde under my home directory. This made no difference.
Another symptom I am noticing is that any desktop widgets that I create all get moved to the upper left-hand corner of the display whenever I reboot and log back in. Any extra shortcut widgets that I add to the panel are also gone the next time I log in.
Again, these same symptoms are occurring on 3 different machines.
These symptom do not occur after a fresh install of FC 10. It is breaking during one of the yum updates but I have not narrowed it down yet as to which update is causing this to happen.

What have I done here and how do I get that session back? I've cleared the /tmp/.X11-unix entries but that did no good. Could I have checked something in Yast that is launching an invisible session?

I have a strange problem with evolution in Fedora 14. I run my own mail servers (Postfix and Dovecot) on localhost. This all worked great in F13 but now evolution refuses to connect to the localhost imap server. If I connect from my laptop (also F14) i.e. not from the localhost all works fine and great with evolution. I deleted all the config and started again to no avail. I also created a new user and logged in with this user and I still get the same so looks not to be user config issue.
evolution --debug=evo.debug.txt returns nothing useful.
Dovecot is listening on localhost as I can telnet to the imap port. Also other imap clients like Thunderbird work fine.
I'm trying to install two instances of OCS Inventory on the same machine using virtual hosts in apache. The apache configuration for it is in it's own file and it works fine without any virtual host. If I add it apache refuses to start without giving any error message. I narrowed it down to some lines loading perl modules, and if I comment them away apache will start again. Some of the modules work, but some of the ones specific to OCS Inventory will not work. I can't understand what the difference is between loading it in a virtual host or not, it doesn't make any sense to me!
View 2 Replies View RelatedI am setting up a new server and am in the midst of testing RAID. This is an Ubuntu 9.10 server. RAID1 (/dev/md1) is spread across 12 one-terabyte SCSI disks (/dev/sdi through /dev/sdt). It has four spares configured, each of which are also one-terabyte SCSI drives (/dev/sdu through /dev/sdx). I have been following the instructions on the Linux RAID Wiki ([URL]....
I have already tested the RAID successfully by using mdadm to set a drive faulty. Automatic failover to spare and reconstruction worked like a champ. I am now testing "Force fail by hardware". Specifically, I am following the advice, "Take the system down, unplug the disk, and boot it up again." Well, I did that, and the RAID fails to start. It outright refuses to start. It doesn't seem to notice that a drive is missing. Notably, all the drive letters shift up to fill in the space left by removing a drive. The test I did was to:

Is removing a disk from the bus a reasonable test in the first place? Meaning, is this likely to happen in a production environment by other means than a human coming by and yanking out the drive? Meaning, is there a hardware failure that would replicate this event? Because, if so, then I don't know how to recover from it.

I have a function in my SOAP server that returns an array. When the client calls this function, it only receives "array", and when I use foreach to print each member of this array, it tells me that this is not an array. If I change the returned value of the function to a string or integer type everything works fine though, so I don't think that there is any problem with the client.I am using NuSOAP library on php to achieve that.I had doubt when declaring the type of return value of the function. In XML schema there is no array type, so I specified the return value as a string like this:
PHP Code:
$server->register("getLocation",

View 2 Replies View RelatedI have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care).
Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

I have a NETGEAR ReadyNAS NV+ with four 1TB drives in a RAID-5 array. This is our primary file storage. This has previously been backed up to a hardware RAID-0 array directly attached to our Windows server. The capacity of this backup array is no longer sufficient. So the plan was, take a bunch of 200GB to 320GB drives (And a 750) I had kicking around, chuck them in a couple of old SCSI drive enclosures I have collecting dust, attach them via IDA/SATA-to-USB adaptors to a USB hub, attach that to the server, create a JBOD array spanning the disks, and back up the NAS to that. Performance is not an issue as this is just to be used for backup, with the idea being as near to zero cost as possible (Spend so far = NZ$100�ish).
The first hurdle I struck was Windows not supporting Dynamic Disks on USB drives (Required to create a spanned volume). At first I resisted using another machine (i.e. a machine running Ubuntu) as I didn't want to dedicate a piece of hardware to backing up the NAS. I then decided it would be acceptable to do this via a VM, which is what I've done.So I have 10.04 running under VMWare Server 2.0.2 under Windows Server 2008 R2. The disks are all presented to the VM. I wasn't sure if I was going to end up creating the array under LVM or something else, but I noticed Disk Utility has an option to create an array, so I tried that. When I add two 250GB drives, the array size is 500GB. When I then add a 160GB drive, the array size drops to 480GB. Huh? If I keep adding disks (Regardless of order) the final array size comes out at 1.8 TB, as per the attached screenshot. Now with the following drives, I expected something more like:
160 + 250 + 250+ 750 + 250 +200 + 200 + 250 + 320 + 250 + 320 = 3.2TB
Am I missing something or making a false assumption somewhere?
I have an array called arrayini which stores numbers. I want to take log to the base 2 of each of the numbers in that array and put it in file called result. I've used the following code to do it.
Code:
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
echo "scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >result
It works fine but its taking pretty long to calculate since I've got about 230,000 items in the array. So I decided to store the result into an array hoping that it'd be faster. I tried the following code. arrayresult is where I try and store the result. The code doesn't work because of the second last line.
Code:
unset arrayresult
size=${#arrayini[@]}
for ((i=0;i<size;i++))
do
arrayresult[$i]="scale = 12; l(${arrayini[$i]})/l(2)" | bc -l
done >FILE2
There is a syntax error clearly.
