I'm working on a project using CentOs 5.3 that uses a solid state drive (SSD) as the boot device. It is desired to configure it such that writes do not typically occur run-time but configuration files can be saved. There are 2 reasons we do not want writes to occur run-time. 1) Writes will wear out a SSD over time. 2) A system disruption during a write can cause a file system error.
I am looking for a procedure to recover the initial installed state of my system with out over writing user data areas. The install procedure has the phrase "will remove all linux partitions" which interpret to mean data partitions, not just /bin and /. Additional background - Was attempting to build a 32 bit cross compile of Mozilla/Firefox on a x86_64 configuration and had a conflict with libgl. Online advice was to remove duplicate libgls from the system (that was bad advice). This led to running yum update.
When I restarted the system I know longer had wireless networking, ntfs mounts and possibly other features I had installed. Further, attempts to update, re-install, erase and reinstall have had no effect on the situation. My assumption is that I need to start with a clean install - which will be about 10-20 hours to reset all the additions I made. But I don't see another solution.
I'm running CentOS 5.4 on an Atom-based motherboard with a quiet, low-power PSU. As the only fan left is a 40mm fan to cool the Intel 945GC chip, I'd like to run a utility to monitor the 945GC and HD temperatures. Ideally, it should be able to run the 945GC fan faster when it's needed.
I had a server with CentOS 5.5 and Asterisk fail today most likely due to the power failure. I guess the stupid electrician turned the power ON and OFF multiple times while changing the burned out fuse without unplugging the PBX. It was set in CMOS to power back on when there is power outage so my two HDDs which were set in RAID-1 now shot.
Trying to start the system and it goes through some check and fixes and then tells me to do Ctrl+D or enter password and run fsck. I have tried both methods and I don't think they yeild anything.
Ctrl+D reboots and same store again with the system fixing and asking me to Ctrl+D again. Putting the password and doing "fsck -y" gives many errors and it fixes it and then it just keeps looping. I am afraid this is making it worst than better. So, after few loops I did few more restarts and just give up. Took out the HDDs and installed new ones and install CentOS+Asterisk so business runs as usual on Monday.
However, I am kind f*ked if I don't get the files out of these HDDs. This is my first time using fsck and also encountering this type of a problem. What is the normal procedure when fixing inodes misplaced in a case like this? and what should I do to at least be able to grab my files?
I have already connected one of the drives to Windows and used Disk Internals (which maps Linux drives) but I see only folders with no contents except for /tmp/ which has contents. While the HDDs were in the system I could actually browse files and they were fine. I am really keen to get the drives fixed but I am also afraid that bad usage of fsck might replace lots of files and burn it all.
this is my first post right here. I'm running on my first Fedora full experience, then I'm not so experienced about the specific details of the distro. Coming from Ubuntu (and certainly sad about Unity bugs), I wanted to know other distros, so I've adopted Fedora as my main OS. I often had some bugs and try to resolve them by myself but, this time, I've no idea about what can I do. So, there it goes:
Recently I've been trying to set up my PostgreSQL server for development purposes. Then I went to EnterpriseDB website and downloaded the x86-64 GUI install bundle, as I always did in Ubuntu (I never had this bug with Ubuntu). After the download, I went on with the installation, doing these steps:
I run the installation with no problem, doing it alright, then I finish the installation and open pgAdmin3, for set up my databases. I log onto my server, put my password for postgres user and create a new server. It's all OK, so when I go to Query Mode tool (Ctrl + E), it crashes along with the pgAdmin.I decided to run the pgadmin script on terminal, looking for more details, then:
/opt/PostgreSQL/9.0/pgAdmin3/bin/pgadmin3: /opt/PostgreSQL/9.0/lib/libuuid.so.1: no version information available (required by /usr/lib64/libSM.so.6) /opt/PostgreSQL/9.0/scripts/launchpgadmin.sh: line 3: 4890 Segmentation fault (core dumped) LD_LIBRARY_PATH=/opt/PostgreSQL/9.0/pgAdmin3/lib:/opt/PostgreSQL/9.0/lib:$LD_LIBRARY_PATH G_SLICE=always-malloc /opt/PostgreSQL/9.0/pgAdmin3/bin/pgadmin3
I've used this program for years on Windows and would miss it if I could not use it with Ubuntu.For people not knowing abt HjSplit here's a link that gives u a basic idea. Try it . Its an amazingly simple and useful software especially when u download movies from net and they are split in to many parts.It's just one of those programs that is tiny and just works.Using this software a big avi file can be splited in to many parts as well as many avi files can be fused in to one avi file.2 things are required for successful installation in Ubuntu ....A) Kylix Library.B) Hjsplit installation.Please note that a Kylix library needs to be installed on your computer before running HJSplit for Linux.
Just wonder is it possible to install non .deb package through the standard procedure of make config etc in Debian, or better not even attempt it.I need to use several engineering, mathematics packages, Matlab, Maple and Ansys,I have been told to use Fedora, but I would prefer to use Debian, as all my computers run on Debian and its stability etc is well known, not to mention the nice people in the forum, Bugs, Evil etc, well known icons.
I am basically very new to linux.. I have rhel 5.2 sever. while the system booting the following error had shown.
touch: can't touch '/var/lib/random-seed ; No such file or directory chmod; can't access'/var/lib/random-seed ; No such file or directory touch; can't touch '/var/log/wtmp ; No such file or directory chgrp; can't access '/var/run/utmp; No such file or directory
I have an issue with normal boot (fail safe boot doesn't have this problem). The boot process just stops and nothing happens, I just see the green background, the white lizard and no moving progress bar. I've given it about 40min without touching it, but nothing happened. If I press escape, the last log print says its mounting/mounted the hard drive. Not until I touch the head pad or press a key, it wakes up and the boot procedure continues. I once had a similar problem on opensuse 11.1 which could require much tickling before booting up completely. This was never seen on 10.3, 11.0 and 11.2, but now its back in 11.3.
I'm new to here and to linux, having changed over about 2 weeks ago. I've had a lot of trouble installing a variety of software and am really starting to despair and regret changing over. Right way to go about things for the installation processes of any of the following software on opensuse11.4 64-bit (I have tried everything I can to no avail): Canon ip2700 series drivers Creative Sound Blaster X-fi drivers Skype iTunes
this is my first thread. Just installed Desktop Kubuntu Natty 11.04 x86_64 and have been amazed by its possibilities. I would like though to install a second OS which is free-ware and unlike Kubuntu but as powerful and userfriendly. Would anyone recommend the followinf?
I am a Windows XP user. During installation of OpenS8uSE on the same PC (for dual-boot installation), I had budgeted a disk space of 23 GB, which I thought was OK for this purpose. Yet, I was advised to resize my existing Windows partition. I had to abort the installation, as the new partition eats away into Windows partition.
That raises a basic question: What is the minimum disk space required for installation of OpenSuSE 11?
The following page recommends only 3 GB space (500 MB minimum). Download Help - openSUSE Then why is the installer trying to disturb the existing partitions? I do realize that this depends upon the choice of software. But I am looking at "default" and "full" options, in which the installer decides what to install.The purpose is to know in advance whether we are starting with the right kind of HDD in the first place.If the user knows this figure in advance, he can avoid a half-way aborting of installation. If needed, he can even purchase a new disk with sufficient capacity.
I am planning to install 10.4 when it arrives. And am not going to upgrade because i upgraded from 9.04 to 9.10 so now i need to refresh the system.But I have all my partitions except root using lvm2 logical volumes. My question is : What is the safest procedure to install 10.4 on an existing lvm2 without losing my files/partitions
- 160gb is where i install CentOS (pretty much the hard drive for operation system) - Lets call this drive A
- Two 1TB drives run in RAID 1, using software RAID (this is where i will store personal data, pictures, movies, music, etc...) - Lets call this RAID 1 setup drive B
I am planning to run a virtual Win Server 2008 using Xen and have that be my domain controller. I will use samba to share drive B and have the network drive map when user login to the domain.
- If for some reasons i have to reinstall CentOS, this pretty much mean drive A will be formatted and reinstalled. Knowing my self i probably will goof up some config in CentOS and will need to reinstall the OS to fix it. Since drive B will be the centralize location for my home network, i dont want to lose the data. Will i be able to re-setup the RAID setup of drive B and still have all the data stored on it intact after a reinstall?
- Is the separation of OS drive and data drive recommended?
- Are there any better way to accomplish my setup? I am pretty much just looking to make a linux file server and windows on client's end.
I'm using Postgresql 8.4.2-2. I'm trying to remote into my server securely. I figure I could do so with ssh. Apparently I figured correctly, as per, [URL] and [URL] I setup the ssh tunnel. ssh -L 5432:serverip:5432 Then I setup pgadmin3 to connect as follows:
An error has occurred: Quote: An error has occurred: Error connecting to the server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
I'm not sure what the problem is. I can connect with Code: psql from the cli after connecting to the terminal via ssh. So I know that I'm using the correct password.
just returned to fedora from a stint with xp for development with xp embedded (acutally pretty cool) before i get all cozy with settings and install programs, etc, etc, what is the upgrade procedure for 13? does all of this go for naught, or are settings kept if you upgrade with yum? i hope the answer is what i want it to be!
i am using linux for couple of years. suddenly i a question arises in my mind. Before loading kernel during booting linux box initrd image loads necessary real mount point, file system, modules etc. but how initrd loads them ?? is there predefined modules list stored in initrd image or something else....what is the background procedure of it
I'm just figureing out the command line, I am trying to find out how to get to the Internet and browse from the command line, also how can you launch any program you want to use from the command line.thanks for the answers,donald Spauldingexectec@zoho.comI can use the GUI but would like to be faster and better
Have decided to stop using Hylafax and our two serial modems on our server running Clarkconnect 4.1 (RHE4.1)What file will I go to to edit so the program and two devices don't start up?I disconneted the devices and the log file is full of the attempts to get the modems working
I'm currently running Xubuntu 10.04LTS as my main distro, but would like to also run Fedora 13 on the same machine.Therefore, I'm more so just after a bit of steer of the best plan of attack to achieve this - best procedure to partition the drive (80gb / i686) and install Fedora etc.
Decided to try to use my console but it didn't work the way I thought it would. What is the proper procedure to log into my console? I've tried to enter data given to me at http://www.zaphu.com/2008/05/30/ubun...-m4a-playback/ It entered the first line of text but not the unwrapped second line. Another line appeared asking my 'neil' login. Tried to enter my password but typed letters wouldn't enter. What do I do?
I am using redhat linux EL5. I am using kernel version 2.6.18-8.el5. In this I want to install mp3 player. I don't know which player is best in redhat. What is the procedure for installing player in redhat. Where I can download RPM Packages.
With Ubuntu i used some software which only had an installation procedure or a package for ubuntu. Program's such as Ailerus or Usenet Resource Downloader. What i would like to is this: Since Ubuntu is Debian-based, is it possible that software, intended for Ubuntu, can also be installed under Debian? Or is there a slight difference in structure between debian and ubuntu that makes it almost impossible to add software, intended for Ubuntu, under Debian?
I'd tried to run HDD bench mark at my Debian Stable called iozone3. It performed I/O actions which took too long. Ctrl+C to terminate process. Everything went as always. It just terminated. Upon completion of program I used laptop for some more time. During shutting down X-Desktop shut down normally. Terminal window was showing command line with lines <Stopping this and that daemon...> but instead of normal black colour background with white text it changed into red background with white text. What does it mean? Is it safe to restart laptop?
I was under the impression that if I have any programs not installed by the package manager, they belong in /usr/local rather than /usr. But if I put the executable in /usr/local/bin, and the jar files into /usr/ local /lib, I get runtime errors about being unable to load the Java classes. So I resorted to putting things in /usr/bin and /usr/lib and it worked fine.Is this something that can only be corrected by compiling differently, or am I missing an installation step?
So I'm getting a new laptop soon, and it ships with Windows 7 64-bit. So I assume I have to use 10.04 64-bit. I noticed that the download page says "not recommended for daily use". I was wondering why this is, and if there were any things I need to look out for when using Ubuntu and 64-bit. I read the older FAQ thread in the closed 64-bit forum, but I wanted to make sure I got more recent information.
