Yesterday I installed a new server with a large partition for my XEN images. This partition is a about 930GB. The installation tooks ages and after he finished I was finding out why that is. The SoftRAID1 I configured is rebuilding the large partition.
View 7 RepliesI have been wanting to increase the fps rate of my current game servers, and I need to have a custom config for this cause I'm only hitting 500.

I have installed a 2TB drive in my dual PIII 866 with 750MB ram. The drive is properly installed and I have configured the drive with 1 partition in RAID1. The array loads fine, but when I add the entry to mount the /dev/md2 /data/repository the following error occurs The filesystem size according to the superblock is 488378000 blocks The physical size of the device is 488377986 blocks Either the superblock or partition table is likely corrupt I have run fsck manually with no errors reported. I have removed the partition and rebuilt the array. The array assembles properly and I can manually mount the /dev/md2, but as soon as I add the entry to the fstab I get dropped to a shell after a reboot. Not sure where to go now?
View 3 Replies View RelatedI recently installed Fedora 13 on an 80 gigabyte hard drive, and it split the space in two, giving root and the normal partition both 36 gigabytes. I need at least 60 gig or more for my home partition. What can I do to shrink the root one? I currently do not have accsess to the install media or a rescue disk.

Not sure on what is going on here. The server is RAID1 through hardware RAID. It was running an unusual high load so I rebooted it. Now it won't boot up. I am getting these errors after the CentOS boot screen:sda: Current [descriptor]: sense key: Medium ErrorAdd.Sense: Address mark not found for data field
end_request: I/O error, dev sda, sector 3040555357

I have a VIA Epia M 5000 system with 2 western digital 1TB NAS SATA drives connected through SATA<->IDE adapter. Everything installs and writes as expected except... grub. It never boots, after a message 'Grub loading' I always get 'error: no such disk'. I've tried numerous times and has been attemping to fix the issue for the past 2 days.
/dev/sda
0.999TB 0xfd linux raid autodetect partition
1GB 0xfd linux raid autodetect, logical partition
/dev/sdb exactly the same
0.999TB 0xfd linux raid autodetect partition
1GB 0xfd linux raid autodetect
/dev/md0
RAID1 of /dev/sda1 and /dev/sdb1
marked as ext4, boot point /
/dev/md1
RAID1 of /dev/sda5 and /dev/sdb5
marked as swap
update-grub2 in rescue mode generates grub.cfg with SET root=/mduuid/UUID_OF_SDA1
then after that there's search --no-floppy etc --set root=/mduuid/UUID_OF_MD0
I'm writing this from memory but simply the two uuids are different. Is this correct? I get those UUIDs to compare from blkid. All partitions are marked as bootable. grub-install /dev/sda and grub-install /dev/sdb produces no errors. grub-install /dev/md0 does not work, complains about superblocks or something similar.
Grub.cfg file contains insmod raid mdraid1x and similar lines, so that should be ok. Grub drops to rescue mode with message error: no such disk. Not device, but disk. Google finds many results for 'no such device' error, but I am not getting that error. 'ls' produces
(hd0) (hd0,msdos1) (hd1) (hd1,msdos1) ls ANY_VALID_PATH produces empty newline being printed, nothing more.
setting prefixes manually does not work, with error message 'error: file not found'. ls (hd0,msdos1)/boot/grub also produces empty line being printed. Rescue CD and auto-assemble of md0 and md1 works, the files are there, everything okay, except grub.
Followed steps 2-5 and purged/reinstalled grub now it boots as it should, NO idea where it was messed up.[URL].. I had 9.10 running in raid1 and upgraded my hardware (cpu, mb, memory etc) and wanted to do a fresh install of 10.04 to get updated. After following the various guides online such as [URL]...It begins to load grub and drops to a "grub> " shell. Which I have to do the following to get it to boot.
Code:
set root=(md1)
linux /vmlinuz root=/dev/md1 ro
initrd /initrd.img
boot
Then it boots up normally and I can use it like any other desktop. I've been over my grub.cfg and /etc/defaut/grub files and cannot find the issue. At this point I'm wondering if the fact it's a raid1 setup is keeping grub from finding it's files.

I want to some how get a list of the packages I installed. I was hoping that I could just list all of the packages that were not installed automatically as a dependency. It turns out that there are 320 packages that match that description (I think). Is there a way to do what I want to do? Shouldn't all of these dependencies have been installed as a handful of meta-packages instead?

When I tried to reboot, my machine started Windows but then "autochk program not found". And I am lost for what to do...
View 3 Replies View RelatedWe have had a hardisk crash in our RAID1 webhosting server running CentOS5 and Plesk. We first realized something was wrong when our main site didn't load but showed MySQL errors. We then found out that the system was in read-only state. Something that also happened the day before yesterday, but we could fix with a FSCK. Then the system worked well til around 18 hours later when it crashed with the same sympoms. So, we rebooted the server and wanted to do a filesystem check again. But the HDD wouldnt even load. It was gone. Unfortunatelly it was not realized that the second disk in the system was also not working any more for some time now. Fortunatelly we had our main site backed up externally though. So we could re-install a fresh box and mounted the two drives to the system. We checked the harddisk. One is practically empty (the older one), the other has almost only files in 'lost + found' but these are all "numbered", no real filenames or so.

View 2 Replies View RelatedI've got a server running CentOS 5.5. I used the automated iptables config tool included in the operating system to allow traffic for vsftpd, Apache and UnrealIRCd. When I send large files to FTP, even from the local network, it works fine for a while and then completely times out... on everything. IRC disconnects, FTP can't find it and when I try to ping it I get "Reply from 10.1.10.134: Destination host unreachable" where ..134 is the host address for the Win7 box I'm pinging from. This is especially frustrating as it's a headless server, and as I can't SSH into it to reboot I'm forced to resort to the reset switch on the front, which I really don't like doing.
Edit: the timeouts are global, across all machines both on the local network and users connecting in from outside.
It is now almost 3 'o clock in the night here, last 5 hours trying to fix this problem. CentOS always runs perfectly here. I am not a genie with the terminal so wanted to install GNOME on my vps, than vnc but didn't work and did a restart.
Now got this:

I have been a RPM-based distribution guy for a long time (redhat,centos,suse). We have a large shared and dedicated web environment that is starting to require more and more linux. I am in a position to switch gears and move to ubuntu if it makes sense. Things that are important to me are:
1. ease of deployment (both servers and websites themselves)
2. patch management
3. documentation
I have CentOS 5.5 x86_64 with Apache, php and mysql.
I have just installed OTRS (helpdesk - trouble ticket system) on that server and no users.
This system works with perl, apache and mysql.
I notice that is slow to respond and at times unresponsive the apache welcome page. code...
I have a vps, and the only way to access my vps is using SSH . putty.
After playing around with my vps, learning how certain stuff works and so on, i somehow messed up my server.
Is it possible to do a fresh install remotely using only putty, and nothing else but putty, of my server with centos 5.6?
I am attempting to upgrade a system from 4.7 to 5.2 using a (now) DVD drive attached to the onboard IDE. Originally I had tried using a remote NFS image and a USB stick but I thought maybe there was a problem with the image. I can get up to the point of the installation of selecting the keyboard for the system and then it freezes and never goes any further. It doesn't appear to be a kernel panic since I can still switch between consoles.
I've got an MSI K9NGM2-FID with 14 drives in it. It serves as a file server for our backup server. It's got a secondary 4 port Silicon Image SII 3114 SATA card using the sata_sil module, and an old IDE Promise FastTrak TX2000. Technically I could have 16 drives but the 750W PS is walking the fine line on tripping it's self-breaker with the 14 drives and 7 fans. I would like to NOT have to disconnect all of this to do the upgrade.
I thought maybe that running the install using the "noprobe" option would help so it didn't detect and load the modules for the Silicon Image or the Promise cards and detect all of the drives but it still gets stuck on the step after selecting the keyboard. The installation info console and the dmesg console don't really provide any useful information. The installation console says:
INFO : moving (1) to step welcome
INFO : moving (1) to step language
INFO : moving (1) to step keyboard
INFO : moving (1) to step findrootparts
And the last lines of the dmesg console says:
<6>device-mapper: multipath: version 1.0.5 loaded
<6>device-mapper: multipath round-robin: version 1.0.0 loaded
<6>device-mapper: multipath emc: version 0.0.3 loaded
Is there a hidden "debug" option that will turn on a lot of extra logging?
I'm trying to create new RAM image file to get my server load raid1 module upon start, I was following redhat documentation & it suggested to use the following command mkinited --with=raid1 inited-raid1-$(uname -r).img $(uname -r) However after running this command I'm getting this message No Kernel available for 'inited-2.6.18-128.el5"
View 4 Replies View RelatedI have installed CentOS 5.3 with Xen on a PowerEdge 2650 machine with 6GB of RAM. As usual, PAE was already enabled so I did not have any problem with utilising all of the memory. However after upgrading to the latest release of the kernel (2.6.18-128.7.1.el5xen), memory available decreased to 4GBs. Then I switched back to the old kernel and 6GB was there. Then finally have switched back to the new kernel and 6GB is again there. So now PAE seems to be enabled but what concerns me is the inconsistent behaviour. (Also I am not sure the reason was the upgraded kernel.)
View 2 Replies View RelatedI am running a dell poweredge 2600 in which i just now did a fresh install of Centos 5.5 KDE. The install went perfectly with no hiccups or errors. I reboot the server and centos dose its normal checking everything and giving a Green"OK" or Red"Error" and everything seems to be fine. I then get to a black screen with a X mouse cursor, i can move the cursor freely and i can turn the Num Lock key on and off and i can do a Ctrl+Alt+F5 and then reboot with a Ctrl+Alt+Del smoothly, but i just cant get the centos to boot up all the way into the GUI.

View 1 Replies View RelatedI have a Bind DNS caching-only server setup that is working. I am bringing up a new AD domain controller that will also be a DNS server for that AD but I don't want it responding to any DNS queries except those that are AD related.So, my goal is to leave this caching server as the primary DNS server for stations on the network and have it forward requests for the AD domain to the domain controller.My understanding is that I just need a forward zone for that domain pointing to the domain controller. However it does not seem to be working.So that leaves me to think that my caching server is not forwarding properly.
For example, this AD is going to have a naming convention of hostname.mydomain.local.If I do an nslookup and specify the domain controller's IP address as the server, I can query addresses that exist in DNS on that server, such as dc1.mydomain.local.However, queries to my caching server times out (I get a response from the caching server if I query mydomain.local but none of the objects in that domain) Here is my named.conf file:
options {
directory "/var/named";
listen-on { 192.168.0.14; 127.0.0.1; };

I'm trying to change some configurations but when I change it from the default options in main.cf, it doesn't actually update the running configuration. I've even restarted the server all together but it still doesn't update it.In main.cf, here is the configuration I've added:
bounce_template_file = /etc/postfix/bounce.cf
bounce_queue_lifetime = 4h
maximal_queue_lifetime = 4h
delay_warning_time = 1h
I am trying to see if a can get a centos 5.5 server setup as an smtp store and forward spamfilter by following the Centos Wiki and the freespamfilter.org guide by Mr88Talent at [url], which relates to another linux distro.
The spamfilter is essentially working! however, i have one issue with DCC.
test problem:
I'm not sure if anyone else would be interested in a Centos version of Mr88Talent's tutorial, but a very rough and completely untested first effort is available at the following url: [url]
Any opinions on this setup or just a total slating of everything i have done wrong would be welcome as i don't want to waste time trying to use a setup that is just not going to be practical or reliable to maintain / keep operational.
I have read that yum update can break this type of system - which concerns me.
The intended use of the spamfilter is for a small business (only about twenty e-mail accounts). However, they still need to reliably receive e-mails (hopefully with less spam though).
I've got a situation where I would normally use NFS, but cannot. So in it's place I need to use a samba share (even though it's linux -> linux). I need it completely open and world writeable as if I had done an rw in an NFS export. I thought I had it as when logged in as a user I can edit delete etc. however the apache user seems to be struggling with creating files. Here's my smb.conf as it stands.
[global]
workgroup = WGRP
server string = Samba Server Version %v
security = user
passdb backend = tdbsam
unix extensions = no
[tmp]
comment = Temp Directory
path = /var/tmp
public = yes
guest ok = yes
writeable = yes
browseable = yes
[sites]
comment = Sites Directory
path = /var/www/sites
public = yes
guest ok = no
write list = siteusr
writeable = yes
create mask = 0777
browseable = no
security mask = 0777
directory security mask = 0777
Note that the drive is mapped as user siteusr. What I can do to open it up more?
I have installed CentOS and Redhat5 on a LVM partition and selinux is enabled. Both OS's share the same /home partition with one user with the same login(gc) and same uid (1000). The problem I am having is that gc can login with all permissions etc on the OS that was installed first (CentOS). For the redhat OS gc can login but cannot write to the home directory (or startx since X needs to write to Xauthority)Here are outputs - 1st CentOS

We have been struggling with a problem with the mysql-server package. This might be in the wrong category because our problems are with it on x86_64. Where the problem happens variables that should populate from the my.cnf don't, on other servers, they do, the my.cnf files are identical except for the server-id
The problem occurs on some of our machines but not others. All are using the mysql-server-5.0.45-7.el5.x86_64 The ones that work, when you connect with a client respond with server version 5.0.45-log source distribution The ones that don't work respond with 5.0.45 source distribution
It's unclear what the differences are between the two source versions and how we wind up with two different versions. One thing that might be involved, the mysql package is installed with both the i386 and x86_64
