Fedora :: F15 - When Ran A Df -h And Found That It Reported All My LVM Partitions Twice
May 26, 2011
I installed Fedora 15 twice last night because I thought I had screwed up the installation somehow when I ran a df -h and found that it reported all my LVM partitions twice (/, /home, and /var) and it also showed /var/tmp mounted on the same logical volume that /var was mounted on (lv02 = /var AND lv02=/var/tmp). I've never seen this before and it definitely didn't appear like this in Fedora 14. Is this something new to Fedora 15?
I'm doing an distro upgrade from 11.2 to 11.3 and for the DVD drive, the repo URL comes up as dvd:/// in ast and zypper. However medium not read is being reported, forcing me to find out exactly what "dvd:///" is pointing to.
My DVD drive is certainly readable and mountable and sits at /dev/dvd (symlink for /dev/sr0). I usually mount it manually, but the problem here is I don't know how to find out what "dvd:///" represents.
I have windows 7 and ubuntu on my computer they were working fine together, so i decided to get fedora. now when i go to the boot menu on fedora it has a list that says fedora (numbers), and other. so i clicked on "other" but it says partitions were not found.
incoming connections are not being reported to my /var/log/secure. I can't see if people are trying to connect. I can't troubleshoot because I can't do anything.
Suggestion: increase the VM dirty writeback time from 5.00 to 15 seconds with: Echo 1500 > /proc/sys/vm/dirty_writeback_centisecs This wakes the disk up less frequently for background VM activity Q - Quit R - Refresh W - Increase Writeback time If I wait it decreases to 50000, but it is still huge!
Situation is duplicated after complete F12 re-install. All defaults are used and no changes performed after install. Just checked again and let computer run idle for a while. Powertop reports 79604 wake-up per second, even more than before. Again, the top cause is "pata_atiixp". Also, performing suggestions of powertop shown at the bottom of the program does not help either. That decreases wake-up by a few hundreds only. Wake-ups are still well over 50000.
During booting of lupu 5.20 ,It starts searching for puppy files in computer disk drives,says boot partitions not found, dropping out to initial ram disk console then /bin/sh: can't access tty: job control turned off # it remains at this position for ever. I have been using lucid puppy 5.1.1 with pen drive through multibooting software of pendrivelinux. I have P2 with 256MB ram, hdd 10GB,usb pendrive 1 GB.
I have installed fedora13 OS on it recently,earlier it has both windows and linux but now only fedora13. My laptop's harddisk has probably some bad sectors and a software package "Automatic Bug Reporting Tool" has reported kernel crash,gnome-panel crash. I reported them upto some extent but in totality all I can't report. How to deal with it, why is it happening, and will it be harmful for any part like CPU,RAM,HardDisk of my laptop?
I'm trying to migrate from Ubuntu but I'm stuck at partitioning part of the installation... The problem is that the partitions are not recognized (I have NTFS + EXT3). I see only /dev/sda and it says it's unpartitioned When installing Ubuntu I had similar problem and I was solving it by removing dmraid.
I have noticed this now for the 125 time that when you mount a volume and use mount to see if it is ro or rw, it says rw, but actually is read only.
Why is mount reporting it wrong?
systema3:/vol/mysql_vo2 on /mnt/mysql2 type nfs (rw,addr=192.168.10.82)
vs
failed to change ownership of `/mnt/mysql2/.snapshot/hourly.5/v240-2-bin.058' to mysql:mysql chown: changing ownership of `/mnt/mysql2/.snapshot/hourly.5': Read-only file system
I was struggling to find the information so I thought it would be easier to ask here. What does the load average as reported by top mean ? To me those are 3 mysterious values, which most likely refer to some average CPU usage and this is all I know about it (not sure if it's true).What is the maximum value for this parameter (I guess the minimum is 0.00) and what does it mean ?
Today, someone who had problems with his usb flash drive showed it to me. I plugged it in my linux box.
Code: cat /proc/partitions only showed Code: sdb
and no partition name (sdb1, etc.). So I ran fdisk on it I deleted all the partitions (4 in all) and recreated a single partition taking up the whole drive and marked it as c (win32 vfat) I exited fdisk (w) and formatted the new partition
I inherited a centos 5.2 server at my work. I didn't know anything about it when I got it except that the fate of the organization rested on my ability to manage it. I've gotten along fine with it. I don't really like it, but it mostly works. I learned a lot in the process. Anyway, I went bought some more ram for the box because, hey, it's a server and it will serve faster with more RAM. So it had 3x512mb and I took out one of the 512mb and put in 2x1gb (it's only got four slots). I rebooted and and top reports 1585152k of ram. It should be 3gb. So I haul out a monitor and keyboard because I want to see if the BIOS sees more. Sure enough, on boot I arrive at a grub/centos boot screen and it says somewhere that I have 3gb, I boot and top still reports 1585152k.
How do I make this computer realize it has more RAM?
When I setup Intrepid (upgraded to Jaunty now), I chose to create a swap partition. I don't remember the size I specified. Here's what I'm confused about When I do 'cat /proc/meminfo' or 'free' or use the system monitor, it reports my swap size as 1262304 KB (i.e. 1.2GB). But if I do a 'fdisk -l', the partition size is reported as 746991 blocks (of 1024 bytes) and if I use the partition editor it says it's 729.48MB. XP disk mgmt shows it as app. 700MB too
Currently I am running Ubuntu on my laptop however my desktop is still XP pro. I want to move from XP to a Linux (Ubuntu) or Unix distro (BSD). My desktop is used as my ftp server, music/network storage, and for syncing my iPod with iTunes. The only thing that is keeping me from totally reinstalling the OS on that computer is iTunes. I know there are tons of applications out there that will sync your music to your iPod however I want to still be able to use itunesu and some other features in iTunes. My plan is to run a *nix os but have xp running in virtual box for iTunes. Has anyone else done this and if you have is it a huge pain? Is there a better way to go about what I'm trying to do? I have tried to get the newer iTunes installers to work with wine but I haven't gotten it to work yet. I get errors and the errors are reported bugs on winehq.
My MP3 Player (Zen:Vision:M) has roughly 60 GB of space and yet Ubuntu insists only 3.6 GB is available. I know this is not true because in Windows the correct amount of room is displayed and can be filled up. Because my music collection is stored in my Linux partition I need to solve this issue if I'm going to actually use my MP3 Player. What is also interesting is the fact that the device doesn't show up in Gparted, System Monitor or fdisk.
When I attempt to look at the Zen's contents through Nautilus I get this message:
Error initializing camera: -1: Unspecified error
And when I update through Banshee every song gives an error of:
I am running CPU tests on a radio controller to determine max simultanious calls. A tool using top was developed so that we could get a good look at what exactly was happening on the process level, however we are mainly interested in one object running on the box.The box has a single core Celeron processsor running the Wind River Linux platform. The CPU usage from my object is frequently spiking over 100%. Doing some research online so far has led me to the fact that a multicore processor can do this however I have found no mention of a single core processor displaying this behavior.
I am having a strange problem on my private nameservers registered with godaddy. There are around 10 domains right now which are using my nameservers ns1 & ns2. After the setup of my nameservers, domains. I checked that the domains are resolving good to the mentioned IP addresses which I mentioned in the zone files but when I am checking the domains on it is showing "Missing nameservers reported by parent" error. I don't know why it is reporting me this error.For example I checked one of my domains spurstone.com & I got the above mentioned error. Although whois database is giving correct results with nameservers NS1.INDEPENDENTADVISORONLINE.COM & NS2.INDEPENDENTADVISORONLINE.COM
I'm running 13.1 on a Dell Latitude D630 with 4GB of RAM. My problem is that Slackware doesn't seem to see all of the available memory. Here are the #s being reported (just including pertinent #s rather than all output)...
On my dell inspiron laptop if I use a live cd to boot into Ubuntu and then reboot into Windows the computer freezes up within 5 minutes. I uninstalled everything that I had put onto my computer since I purchased it (less than a week ago) in desperate measures because I was ready to take it back and play stupid to get a replacement. Once I went on an uninstalling frenzy my problem was fixed, but I had to know if it was from a program I installed or the live cd I used so I tried it again and sure enough, within 5 minutes my computer was unresponsive. I was using usb flash drives for my live cd and this was on a different flash drive than the first. Just thought it should be known, and I'm not doing it again once I fix my less than a week old computer from this again.
I have created a folder including some html link pages in /test/htlink . Now I want to create a soft link of that folder as htlink -> /test/htlink in /var/www/html . Now when I m browsing the folder , its erroring (404 Not Found) folder is not found on the server . I have given 777 permission on every file-folder in /test . No firewall & no SELINUX .
After installing 64 bit 11.2 with no apparent problems: computer hangs up on desktop boot opensuse 11.2-2.6.31.5-0.1, however I can boot from failsafe opensuse 11.2-2.6.31.5-0.1. I had problems trying to install Ubuntu so I checked out the opensuse. I do not know if this is an easy fix! I decided to avoid buying anymore windows system software. I ran memory test with no problems. The firmware test reported 4 errors. I have windows XP installed on other hard drive - no problems there.
I need to install a package. For that I need root access. However the system says that I am not in sudoers file. When trying to edit one, it complains alike! How I am supposed to add myself to the sudoers file if I don't have the right to edit one? I have installed this system and only administrator. What can I do?
Edit: I have tried visudo already. It requires me to be in sudoers in the first place.
I have got four webservers and one fileserver, all running Karmic and kernel 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux.A folder on the fileserver has been exported using NFSv3 with these options: rw,async,no_subtree_check and mounted on all four webservers with these options: efaults,rsize=32768,wsize=32768,noatimeThe webservers run Apache+PHP+APC. Some php-files include other php-files from the nfs mount, and are requested by users very frequently (~ 100 times per second). Sometimes but not always if I alter an included php-file using FTP (the FTP server is ProFTPD and runs on the fileserver), the file seems missing:user@webserver1: ~ $ ls --full-time -al /path/to/included/file.phpls: cannot access /path/to/included/file.php: No such file or directoryI can repeat this command for hours, but the file keeps missing. Until I query the directory:user@webserver1: ~ $ ls --full-time -al /path/to/included/ | grep file-rwxr-xr-x 1 1002 1002 14294 2010-07-04 21:11:30.000000000 +0200 file.php
I have set logwatch to report daily the logs, somehow since last week i get below message. A total of 1 possible successful probes were detected (the following URLs contain strings that match one or more of a listing of strings that indicate a possible exploit):
I tried to load a simple driver program. I am using RHEL5. When I tried to compile my 'driver.c' program it shows the following error:

I removed an ntfs partition I had in my HD and then resized my home partition with gparted to occupy all the available space. The resulting partition is supposed to be 129GB, and gparted/partition magic see that size. But the system does not, and all tools report the old partition size and the same free space I had before resizing.
