Hardware :: Corrupted Drive- Mechanical Or Logical - Fsck Repair?

Sep 7, 2010

I was working on my RHEL 5.2 workstation yesterday when the OS became flakey. first I noticed that some software that I had running was outputting and error that it was unable to write to log file because permission was denied - I've never seen this output before- it would have been writing to my home dir running under my user name. From an open terminal, i did "ls -al" and saw that many of the permissions the files in my home dir were listed as "????????" some were still "rwxrwxrwx", as well, many files were highlighted in the colors set for links and root privileges.

I tried to start a new terminal, and it failed. then Gnome crashed. When I reset the Machine, I got through grub, and into the startup, and after finding the Volumes, the startup failed with a Kernel panic:

giving several errors- like:

I dont have much experiencie with this stuff, but it looks obvious that somethig like the MBR or wherever the partion information is stored might have been corrupted.

What I dont understand is why I can get into GRUB (its a dual boot Windows Vista, RHEL machine). I'm guessing that this means its not a mechanical problem, because I can get RHEL to begin to boot which i think is failing somewhere around the /etc/rc.d/re.sysinit script, and also can get Vista to bring up the inital windows screen and a mouse pointer on spanning both of my screens which i think means that it must have at least loaded my ati drivers for my dual head radeon 4850. windows hangs there however.

I've tried the RHEL 5.2 rescue disc, and it doesn't recognize any Linux partitions.

I ran the system diagnostics out of the dell bios and it came back with a failed HDD : Error code 0142, but from digging around a bit I've found that this is a very broad diagnosis.

My concern over it being a mechanical problem is that I'm not sure that I want to try to run any further diagnostics, or any of the disk utility programs that i've seen listed here on linuxquestions, as it might damage it further, and there is some data that i would really like to get off this disk.

Ubuntu :: Looking For Electrical CAD Not Electronics?

Oct 22, 2010

Can anyone point me in the right direction ?
I'm looking for electrical cad software similar to AutoCAD Electrical or PCSchematic Automation. I need something to do WIRING diagrams as apposed to circuit schematics like Egal. Electrical not Electronic. I'm talking about power distribution, fuses, relays, PLCs, motors, solenoids, switches, buttons, and cables. I am not talking about transistors, capacitors, integrated circuits, and printed circuit boards. Sorry to put such a fine point on it, but there are a lot of PC board design tools out there that use the word "electrical" in their description, but are not useful for diagramming the wiring connections in a machine.

I think an electrical cad program should have the following features in order of importance code...

Here is an example of the sort of thing, but wiring diagrams can represent an entire factory, documents with hundreds of pages.

Server :: 2 Separate External Hard Drives With ESata To Minimize An Electrical Failure To The Drives?

Mar 26, 2011

I am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data

Software :: CAD Software For Electrical Diagrams?

Feb 15, 2010

I'm looking for Linux software capable of producing Electrical diagrams. The Windows standard, is of course, AutoCAD (Electrical), and I'm wondering if such a program exists for Linux, specifically the Debian branches (I'm using Mint).I'm in the Fire Alarm industry, so the candidate I'm after will have a library of symbols pertinent to Fire Alarm system design.

Debian :: Installing I386 Packages Prompts Removal Of Amd64 Packages

Apr 8, 2015

I am working on a project which targets both 32 and 64 bit architectures at the moment. My system is amd64. I added i386 architecture using this guide. However, my problem is

Code: Select allapt-get install package-name:i386

prompts the removal of currently installed packages (amd64 arch.) which is the problem.

Code: Select allReading package lists... Done
Building dependency tree       
Reading state information... Done
The following extra packages will be installed:
  libportaudio0:i386

[Code] ...

Some of the packages I am talking about are

-libegl1-mesa-dev:i386
-libportaudio-dev:i386

Now, as of now, I want to carry out the compilation using 32 bit libraries, however, I really don't want to install 64bit version of all prerequisites each time I switch the compilation from 32 bit to 64. Is there any way to have both architectures at the same time?

OpenSUSE Install :: Upgraded From 11.2 To 11.4 - Switching Systems Packages To PACKMAN Packages

Aug 31, 2011

I just upgraded from 11.2 to 11.4 and the installation/upgrade worked just perfect. I than followed the instructions in the "New User How To/FAQ", "Multimedia and restricted format" post. I was following the instruction in the 11.4 section. I added the additional repositories as explained. I then was on the section where it talks about going into software management and selecting the "Packman" repository and clicking to "switch systems packages" to the versions in this repository (packman). I than click this link and the "warning" screen appears and I am present with conflict resolution after conflict resolution dialog. It just seems that there are some many conflicts, it just seems wrong and I canceled.

The installation/upgrade appears to have worked just fine. My mail is there, audio and dvd play back worked the first try after the upgrade. I am not clear if this is what I should expect or their is something wrong or if I even need to complete this step for a successfully installation.

Ubuntu :: Apt/dpkg: Segregate User Application Packages From System Packages?

Dec 2, 2010

Is there a way using dpkg or apt-get to segregate user application packages from system packages? What I envision is an /apps directory structure that can be the install target for selected packages so not to "clutter" the storage areas for the system administration files/packages - maybe even with permissions set so that (a GROUP of) users could install packages on an Ubuntu server w/o SysAdmin guidance. This could also allow 1)system upgrades with or w/o including these packages, and 2)the sharing of /apps (via NFS) among common Ubuntu systems. Is this doable using the dpkg or apt maintenance tools?

Fedora Installation :: Preupgrade Leftover Packages - 176 F13 Packages Remaining

Nov 17, 2010

I recently upgraded from F13 to F14 using "preupgrade". This is the first time I've used preupgrade. So far, F14 is running OK. There are some leftovers from F13 and I'm wondering if this is correct.

Q1: There are 176 F13 packages remaining. [alfrugal@localhost Documents]$ rpm -qa | grep fc13 | wc -l 176 Is this OK? FWIW, after the upgrade, I ran "package-cleanup --orphans" as recommended by the "preupgrade" page on the Fedora Project wiki.

Q2: Also, my GRUB menu was correctly updated for F14, but it still contains the three entries it had for F13. Is it normal for the preupgrade process to require the user to clean up the obsolete entries from the GRUB menu?

Ubuntu Installation :: LUCID: Downloading Repositories/Packages - Get This Message " Unable To Find Expected Entry Deb-src/binary-i386/Packages In Meta-index File "?

Jun 24, 2010

I did the UPGRADE from Karmic Koala to Lucid, and everything was going well. But now I've been having problems with the UBUNTU UPDATE tool for the last 2 weeks. Every time I try to do an update check on the packages, I get the following message:Failed to fetch http:[url]....Release Unable to find expected entry deb-src/binary-i386/Packages in Meta-index file (malformed Release file?)

Some index files failed to download, they have been ignored, or old ones used instead.I've tried changing the servers to MAIN and others, and still no way to solve it. I've also checked for other posts, but haven't found a solution yet. Here's my SOURCES LIST (gksudo gedit /etc/apt/sources.list)# See http:[url].... for how to upgrade to # newer versions of the distribution.

Debian :: Downloading Packages With APT?

Jan 10, 2011

APT - it really has me mystified at times so I'm looking for an idiots guide on how to use it. I've googled and read the APT How to on the Debian site, as well as a lot of other APT pages, so I understand what it does and the command structure, but I can't seem to download one off packages from the Debian site.

I've managed to get the updates to work (ran an update the other day) so I know my source file is working (my source.list points to deb http://ftp.uk.debian.org/debian/ lenny main) however I don't understand/can't figure out how to get single packages from Debian.

As an example I want to get the rsynch package which has a download page in Debian and my mirror in the source.list file can be used. However when I do apt-get rsynch I get an error message that says it can't be found.

Looking at the Debian package website it does say that the rsynch package can be requested from the subdirectory of pool/main/r/rsync/ at any one of the listed download sites (of which the site in my source.list file is one of those listed). Do I have to add the pool/main/r/rsync/ information to my sources.list file, or add it to the apt-get command?
