here is the problem I am facing. My system [ fedora 11 with all updates installed as of nov 27] suffered a power interuption.[ well that happens I dont have an UPS] here is what happen then
1- when i restarted i get stuck with the "install problem with gnome power manager" that prevent the desktop to launch. I found this to be well documented and I ssh'd [ for some reason cannot get the consol] my system and tried as root to remove gnome-power manager with yum remove power manager ... well the command hang out doing nothing and I have to close the session and reconnect... CTRL C dont even work.
So I had another problem. I started checking my system and when I tried df, I received the shocking following answer
My mom's ubuntu 10.04 laptop ran out of battery during a software update and now it will not boot.
When attempting to boot normally, it comes up to the login screen but the keyboard and mouse do not respond at that point. Ctrl + Alt + F2 doesn't work.
Choosing recovery mode also does not complete. The last line showing is "Begin: Running /scripts/init-bottom ... Done." Ctrl + Alt + F2 also doesn't work at that point, although Ctrl + Alt + F7 changes to another screen of text with the last line showing "init: udevmonitor main process killed by TERM signal".
I've tried booting from a 10.04 live CD and ran fsck which did not find any problems on the linux partition. I can also mount the partition and view files.
I have a little/big problem. This morning, I dont know why, but suddently my hard disk was full. I thougt that the temporary space grew too mucho and I thought if I restart my machine, everything would be nice but no. Now in the logging screen comes messages that some components cant be load and so I can't go in my Fedora
I tried to access to my partition with Knoppix-livecd and free some space, but it seems that Knoppix can't access to that partition. I have installed fedora 12.
I am investigating full disk encryption and have made a DD copy of the hard drive which has been encrypted, this DD file is stored on my computer for analysis.
First question is - Anyone know how i can access data in this DD file even though its been encrypted?
Second question - Is there a DD command where i can image the systems memory? I ask this because when a system is turned on, to get past the pre-boot authentication stage you need a password. From what i understand, this password will be passed in to ram when power is applied to the system. Making a copy of the memory will also copy the password?
i'm curently compressing a big 100GB file with 7zip on a system with an intel 2,66Ghz quadcore processor. Allthough 7zip uses 4 cores to compress the file, it still uses only about 40% of the cpu performance. The cpu isn't doing anything else, nothing heavy anyway.
I started compressing 8 hours ago and the compression is currently 47% done. Reading and writing the files isn't very fast so my harddrive isn't slowing the process down.
So what's the holdup? There is still 53% of work to be done. Is it for some reason impossible to do this faster?
im installing ubuntu onto a friends ibook, but am first running it live off the disk. it runs well, except for one thing, the display has a problem,i guess it seems like its tiled on the monitor, instead of fullscreen, it has a full desktop taking about 2/3 of the monitor, a sliver of the same desktop right below it, and a line of black to the right.
One day I was using Gparted and following this I rebooted and had this came up
"Install problem! Configuration defaults for Gnome Power Manager have not been installed correctly. Please contact your computer administrator."
Initially from reading the forums I figured it was because my Ubuntu partition ( I dual boot Windows 7 and Ubuntu 10.4) filled up for some reason.
I used a boot CD and cleared some files in /media. It seems like I kept about 17 GB of backups there for some reason.
The problem is that even though I cleared this out, I still have the same message.
I could just reinstall, but I want to try to keep my data for once, especially my virtualbox harddisks, unless someone can suggest a way to save it and reuse it.
i'm having issues in trying to copy files from one hard drive to another. The destination disk is not full yet I get the message "Error creating directory: No space left on device".
I am running Debian on an ARM module (BananaPi).5 minutes ago, i started upgrading the system, but fortunately the power cable moved and the system closed.Now i open it up again and i'm trying to re-upgrade the system but i'm always getting this message
# apt-get upgrade E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
I made a huge mistake. I was installing dtc-toaster in a Lenny box, and i accidentally closed the aptitude window. Then I opened another konsole (I have kde 3.5 installed), and I couldn't switch to root via "su" command. I can't remember the error message that i got, but it was something like "module not recognized".
Next i reboot the PC, and when I tried to login in tty1, system saids that root "is not a valid username". I had no better luck with other users.
As I'm not an experienced user, I really don't know where to begin. The good news are that starting in recovery mode seems to work.
I have no extra data by now, except that I ran fsck (from a System Rescue CD) on the lenny root partition, and it found no errors.
I'm on 10.04. Cloning a vdi yesterday, I managed to produce a 'disk is almost full' message. Deleted some movies and wanted to try the cloning again today, but starting my laptop, I get an ugly gray login screen.When I login, it looks almost good (some console writing to fast to read) but then it falls back to login informing me 'Install Problem: The configuration defaults for GNOME Power Manager have not been installed correctly."
So i just installed ubuntu server 8.04. Got everything set up and started putting my files on it. 6 Hours of copying later I get a message saying that my Disk is full. This is a 1.5TB HD and it stopped copying at 269GB. fdisk shows the drive as 1.5TB, and ls -sh shows that only 269GB have been used. Yet I cannot add any more files. The other weird thing is that df doesn't show the hard drive, yet I know it is mounted and accessible. If it makes a difference I have it formatted to ext3.
I have a Samsung N135 notebook which boots well from USB. When I travel, I am afraid to damage the disk due to shocks. When I boot from USB and dismounts the build-in disk are the heads parked away from the platters? Is the disk not spinning at all? Is there a command to force power off of the disk!
While using my computer the other day (I was sending an email) it suddenly turned off. I didn't get any low power warning, but I was running on battery and had my iphone charging from a USB port.
As I didn't think there was low battery, I just turned it back on again. As it was booting I saw the battery light flashing, indicating low power. I went to get the charger, but before I got it, mid boot-up it turned off again.
This seemingly damaged something hard-disk-wise.
Upon turning it on again it dropped into busy box with some message similar to this:
Quote:
No init fount. Try passing init= bootarg.
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu7) built in shell (ash) Enter 'help' for a list of build in commands
(initramfs)
That's not the actual message (copy pasted from another post) but the message is VERY similar to that.
If I "exit" busy box, I get a load of message about "kernel panic" before it freezes up.
I have booted a live USB (what I am using now). I thought since it wasn't cleanly unmounted, simply mounting and unmounting would do the trick. I was wrong.
Code: ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
[Code].....
I had previously ran e2fsck (after checking it was unmounted) but it wouldn't run also because it was reporting that the device was already mounted, busy, or being exclusively used by a process.
I don't want to do any more for fear of causing further damage.
I am astounded that such damage can be caused so easily!
I do IT work for a decently-sized bookstore. Over the past year or so we have had a recurring problem crop up where file transfers with networks outside of our building will be interrupted, or those receiving our uploads will get truncated files. It is an intermittent problem and I have not been able to narrow it down to any particular day of the month or time of day. Files that are dealt with in our web browsers have no issues - I can happily download and upload large files all day without interruption. Yet when our little postage meter machine tries to connect to its update server, it sometimes has its connection interrupted downloading its update files. Our credit card machines sometimes have trouble holding a connection long enough to batch out, and our storewide POS system often has to resend its credit batch multiple times before it can maintain connection long enough to push the whole file through. One server daily ftp's a ~11mb file to an associate, and a few days a month they will receive a truncated file that appears to have been cut off mid-transfer. Our bandwidth is handled through three T1 lines that share phone line and internet service. Our voice calls never get dropped and have good line quality, but mobile credit card terminals will have trouble maintaining a connection when they dial out.
I'm thinking this is either an ISP issue or an internal network problem. I don't know what protocol the mobile machines use, but it's possible it could be restricted to ftp or, I dunno, telnet? Maybe a port forwarding conflict? Files sent internally have no problems, so I'm thinking it's something at the firewall/proxy/router stage.
Our servers run a number of *nixes: our central databasing/pos is handled by an IBM RISC box running AIX 4.3; our DHCP server runs Debian Sarge 3.1; we have a Ubuntu 8.04 LTS box running a squidproxy setup using squidguard for url filtering; firewalling is handled by a Debian 5 box running Untangle. Our ISP provides us a 4.5 Mb connection via three T1 lines that provide shared bandwidth for our digital telephone lines and internet.
Could anyone recommend a method of creating a full disk image. I have the Acronis bootable media, would this work to backup Linux partitions? I'm thinking that Acronis doesn't know or care what is written to the disk as it works at a lower level.
The only reason why I don't use Linux (even though I prefer Linux over Windows, and can do everything faster and more efficiently) is because each time I try to learn about dm-crypt I give up.
Can someone point me in the right direction for full OTFE on Linux (like TrueCrypt)?
I am trying to upgrade to 9.10 but it fails because the disk is full. I am running a Dell Mini with 16GB SSD...so there isn't a lot of free space to begin with. Added to that, I have some hefty applications (rosegarden, audacity, skype, etc) which I kind of need. Am I better off just sticking to 9.04? Are there any good ways to clean up the system and get rid of stuff that might be sticking around? I did apt-get clean and it didn't clean enough.
I am using default USB Startup disk creator for spreading new versions of ubuntu on all my machines. In 10.04, I point it to GnomeLiveCD of 600Mb, and usual 4Gb flash drive. And the application says I have not enough space.4Gb is empty, fresh formatted, with right partiion. It is OK in short. Do somebody know what to do with app?
The disk on this machine was full (0 bytes available). I rebooted and now it just goes to a blank screen. I thought I might need to free up some space for something, so I booted to a live cd and freed up some space. Still boots to a blank black screen.
I do know about cold boot attacks. But I ran across a couple of posts/websites that had me wonder if it is possible, without the passphrase, to just remove the encryption?
In fact I'm not the systems administrator, but I have a strange problem unzipping a file. I think is a problem of memory or swap space or somethin similar, but I'm going explain the problem in detail: Distribution: Red Hat Enterprise Linux ES release 4 (Nahant Update 3) I'm connected as root. I have this zipped file: -rw-r--r-- 1 root root 678183271 abr 7 15:30 Master032010.zip it contains a 2,4G file
My system does not power off completely after I trigger the "suspend to disk" function. The monitor gets blank and the usb-mouse does not light anymore, but the power led is still on and the pc fans can be heared. Interestingly, neither pressing the power button nor the reset button starts the pc in this state. I have to unplug the electrical power and then press the power button. After that, the system resumes nicely from the hibernation state as it should. I know that the hardware itself is capable of powering off because it worked perfectly before with opensuse 10.2, and I didn't change any bios settings either. I tried the option acpi=force, but to no avail.
I run Ubuntu Netbook 10.04 on my EeePC 1005HA. I'm going to get a SSD for it eventually, but I can't afford one right now so it's running from a 200GB hard disk I scavenged off a dead laptop.
I went in power management and set the option that says "spin down hard drives whenever possible", but this accomplished a whole lot of nothing - whenever the computer is on, the drive's spinning. I ran hdparm -y and the drive clicked off, and then promptly spun back up after a few seconds. Iotop shows occasional tiny bursts of activity from "jdb2/sda1-8", which I don't really know how to interpret, but I don't have anything weird installed so I'm assuming this is normal system operation.
Now, what I need is some sort of application, utility, command - anything - that forces the computer to keep all filesystem changes in RAM with the drive shut down; every five/ten minutes or so (this would hopefully be configurable) it spins up the drive, dumps the filesystem changes to it, and spins it down again.
I realize this presents data loss risks related to crashing and poweroffs when the cache hasn't been dumped to disk, but I'm willing to risk it as Linux never really crashes at all, and since it's a netbook power failures won't cause unexpected shutdowns.
I would like to configure my Debian Jessie system in this way.
Two partitions:
1) /boot on /dev/sda1 2) everything else on /dev/sda2
I want to encrypt the second partition with LUKS. And then install over it a LVM volume. Inside the LVM volume i will create the / (root), /var, /opt and /home virtual partitions. In this way, i'll get asked only once for the password to decrypt all partitions. Because if i don't use LVM, then i'll get asked for the password for each encrypted partition.
I can follow and understand almost everything of this HOW-TO for Archlinux: [URL] ....
Only two passages are unclear to me:
1) Configuring mkinitcpio
I don't understand what i should do here in order to complete this. What should i do in Debian to configure "mkinitcpio"? what is the equivalent thing to do here?
I thought that the kernel would automatically recompile itself with all installed modules on the Debian system, once cryptosetup/LUKS or LVM2 get installed.
2) Configuring the boot loader
I don't understand what should i write in /etc/default/grub. Will GRUB automatically load the LUKS and LVM2 modules? Also, I don't think that i could boot the system in this way:
