I'm trying to install RubyGems, but when I run:
# yum install rubygems -v
...yum displays "Loading mirror speeds from cached hostfile" and I can't get any further. The same thing happens when I try to run:
# yum upgrade
I'm running CentOS 5.2 on a MediaTemple (dv) server.
So everytime i try and use the "yum" command. for some reason it doesn't go past this point: "loading mirror speeds from cached host files". i cleaned up the cache and rebuilt the OS again, and im still getting this problem. would this be a problem with my internet connection? I'm using CentOS 5.5.

what can be the problem.I think it is related to proxy but i am unable to resolve.
I recently setup a software RAID1 with two hard drives for testing. I manually unplugged one hard drive to test redundancy and it was fine. I then did the same to the second and plugged back in the first and it was fine. But when I plugged both back in it is only loading one of the mirrors instead of both. I am guessing when the mirror (failed), at least as far as the system knew it removed it from the load sequence to prevent data corruption... how do I go about re-enabling it?.

when we do enter on a folder it take some time for loading the folder depending on the no of entries in the folder . If the folder has more entries it take more time to load and if less no of entries then correspondingly less time . the delay in loading the folder varies due to reading of the folder entries in advance . SO what i want to know is that what is the MAX no of entries read in advance while opening a folder in linux and also how can we calculate this
View 4 Replies View RelatedI have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?
have the latest Vbox installed on CentOS 5.4, i have a XP home VM & Server 2003 VM set up. Im using the T1000 Emulated network driver and only getting 100-150mbps throughput when checked with QCheck. I tried the virtio-net (paravirtualized) drivers and only getting 50-90mbps using it, which i found odd. Is there any way i can increase the througput to my VMs? I seen some people on forums talking about getting 300-350mbps, but im no where close to that. When i check throughput to the host (CentOS) i get at least 800 mbps.
View 2 Replies View RelatedI installed fedora on my laptop and everything went fine, i installed my bradcom drivers and rebooted.
Next step was kmod for nvidia but when i rebooted i couldn't use fedora anymore cause loading freezes at some point. same thing happens to my desktop pc, where i solved the problem booting with an older kernel (this time i have an error saying "eth0 link not ready" or something like that). Everytime i try to boot with a more recent kernel loading freezes. The point is...i can go through with my desktop pc by choosing another kernel, but i can't even boot with my laptop.
I was not able to install any version of Ubuntu. Everytime when the splash screen would appear, the computer would freeze and no hard drive activity would be present. The only way was to use the alternate install version of Ubuntu 10.10. Though, the splash screen problem persists. After the Ubuntu boot screen disappears, the splash screen appears with the coursor. About 3 seconds later it becomes unresponsive and the hard drive light stops showing activity. After reading a lot, I think it's my video card driver. I'm a complete newbie, so any commands need to be written out so I can just type in and cross my fingers. I can boot into the GRUB recovery mode. I log in and have a text based setup at this point.You know, I can type sudo commands and all that jazz. How can I fix my video? The graphics is not integrated. It's a 32mb nvidia TNT2 PRO.

I am using grub4dos 0.44 but can't boot directly into Kubuntu. The bootup freezes at the step of reading the initrd. Can't copy 'n paste the exact bootup-message but it looks similar to this one, I found on another forum-thread:
Code:
Filesystem type is fat, partition type 0x06 [Linux-bzImage, setup=0x1400, size=0xcff87] Unlike the guy who posted the two lines above, I installed Kubuntu on an ext3-partition (hd0,5), (which is /dev/sda6 in Ubuntu) and without an own bootloader, since I wanna use grub4dos instead of grub2. The installation is fresh - the initrd-file shouldn't be broken. My menu.lst looks like this:

I'm using Arch with the latest updates and I'm pretty sure this is a software problem.Basically about one out of five times my system freezes at "Grub Loading Stage 2". Whenever this happens, I usually just reset my box with the reset button and it will boot up just fine the next time.I originally put it down to being a defect in my hard drive which is probably three years old now at least. However, last week I bought a brand new 1.5TB drive. I removed my old drive and am using only my new one. Same problem.I Googled for this problem and found a bunch of posts with the same issue as I'm having, yet all of those issues are with people that dual boot with Windows. I don't. I only have Arch and no other OS on my system. I then tried reinstalling Grub and that doesn't seem to have solved it.I'm hoping someone can help me out with this. I hope it's not a hardware problem. Any help is VERY appreciated as this problem makes me worry that something worse is going on.

I am trying to create a local mirror/repository for CentOS 5.6 for updates and network installs. I have read the page here on the site about how to do it over and over again, and I still can't figure it out. I have already created the directory, but right after that, I can't go any further. I know this is much easier than I probably think it is. Would someone mind telling me, (in beginners terms) on how to do this? I just want the 'os' package and nothing else.

View 4 Replies View RelatedI am trying to install Fedora 12 x64 on my 27" iMac 10,1. I have tried both the installation dvd and the gnome live cd (both x64 i did not try the x86). On the installation dvd I get as far as the menu giving me the boot/install options - I have tried to install both with a basic video driver and the regular install/upgrade option - both times it begins loading components for the installer program (/sbin/loader) etc. After it loads sbin/loader and mounts the partitions it freezes with half the screen being the terminal txt beforehand and the other half being just a standard fedora logo w/blue background. It is not much different when I try the live-cd the only different is it does the exact same thing when the timer for automatic login is done. Any possible command line arguments that I could use to stop the graphical corruption?
View 2 Replies View RelatedI recently upgraded from Hardy to 9.10 Kubuntu. The install went smoothly, and when I boot up, the loading screen (the one with the progress bar) does its thing. Then I see the 'waiting' cursor (in Kubuntu, the two dots chasing each other around in a circle). I see this for about two to three seconds, then the entire thing freezes up and I can't do anything, including switching to a virtual console. How do I figure out my system's dying words so I can figure out what's going wrong? As a (sort of) aside, when I open files in /var/log for reading with cat <file> | less, I have to Page-Down a whole bunch to get to the most recent stuff. Is there a way to jump to the bottom, or read with something other than what I have been using?

View 6 Replies View RelatedI was puzzling over the nss dependence problem that people are having in upgrading 5.2 to 5.3. The issue is clear (that the mirror people are using for [updates] is not pointing to the latest set when an uptodate mirror may be being used for your [base]). My question is though how the mirror list decides whether a mirror is fresh. According to [URL] then this mirror [URL] is "green" which presumably means that the system thinks it is up to date (last probe was 1 hour ago). However if you look at the files on the mirror now (12:54 BST, Apr 1 2009) you see that the date of the 5/ branch is 24-Jun-2008. Thus this host is not ready to give you updates to 5.3. Is this a bug?
View 2 Replies View RelatedI am using LVM2 Clustering to mirror logical volumes between 2 different storage arrays ( iscsi target hosts). Everything is up and running fine, but I would like to be able to monitor the status of the mirror(s), and "re-sync" them if necessary.
I have attempted the locate the information from Google. From what I have read, lvdisplay -v should tell me whether the mirrors are in sync, but it either is not, or I am simply miss reading it. I have come also across information stating lvchange -m [ 0 | # ] should be used to add or remove mirror copies. Is the is correct / only way to "resync" a mirror, in the event that I can determine the mirror is actually out sync?
For those who are familiar with Symantec's VERITAS volume manager, I am looking get the equivalent information related to plexes from vxprint, the equivalent function from /etc/vx/bin/vxreattach -br, and the progress information from vxtask list. I hope the information is currently "search challenged", or I am simply not fully comprehending what I have found.
I've just set up the local mirror for my 96 CentOS 5 workstations. The mirroring script is taken from public-mirror howto and looks like this:
#!/bin/sh
rsync="/usr/bin/rsync -avHzL --delete --delay-updates" # replaced -q with -v for debuging purposes, removed --bwlimit, added -L to follow symlinks
mirror=centos.politechnika.lublin.pl::CentOS # tried several different same result
[Code]....
I tested mirror consistency by putting the mirror addres I'm syncing with, directly into repo file. Than yumex works fine. I tried several different mirrors with the same result.
After reading a lot of docs, I'm still having problems using wget to download a Centos repo from a mirror. Here's my best attempt so far:
$cd /repos/centos/5.4
$wget -r -nH --cut-dirs=3 -np [URL]
Of course I get all the unwanted index files etc, but I seem to get a lot of other downloads from the mirror, not just their 5.4 directory. It's like it's following other links on the web pages. Maybe I should be using "ftp://" instead of "http://" considering it's an ftp site, but I seem to have connection problems that way.
since yesterday, this domain has been painful slow and the only fix is removing it from /var/cache/yum/updates/mirrorlist.txt the last straw was about an hour ago, when 10kb/s was the max bandwidth and I had to download perl and glibc * glibc-common it would have taken over an hour. once removed from updates/mirrorlist the other mirrors picked up the slack and I was back in business,
