CentOS 5 Hardware :: Added HDD - Server Fails To Restart
Apr 27, 2010
I have a issue that could get me fired, so I would appreciate your input. My knowledge about linux is limited
The company I work for has a Dell Poweredge 6850 that keeps pretty much everything (databases, websites, etc). The server had a Virtual Drive created from 2 Physical Drives. Since the HDD space was getting low, we got a new drive, inserted it, formatted and rebooted the system. But the system now refuses to start, giving an FAILED message, something related to EXT2 partition that cannot be read at /dev/hda1

I have just been told that httpd was not running on my Centos virtual server. It seems that my hosting company rebooted my server 2 days ago and that httpd restart failed due to:
Starting httpd: httpd:
Syntax error on line 213 of /etc/httpd/conf/httpd.conf:
Syntax error on line 2 of /etc/httpd/conf.d/proxy_ajp.conf:
Cannot load /etc/httpd/modules/mod_proxy_ajp.so into server: /etc/httpd/modules/mod_proxy_ajp.so: undefined symbol: proxy_module
I had worked around and forgotten about this some time ago. The problem arose because the most recent httpd update installed proxy_ajp.conf into /etc/httpd/conf.d which was then loaded on restart The trouble is I do not use mod_proxy (I think just to try and get a lean and mean web server) and proxy_ajp.conf does not check if mod_proxy is loaded before it tries to LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
Hence httpd fails to restart. RedHats's bug tracker lists this as an old issue (which was never resolved) [URL] My workaround was to rename proxy_ajp.conf to proxy_ajp.conf.orig so that httpd would start up correctly. However any updates simply reinstall proxy_ajp.conf and so IMO the problem needs to be resolved at source. how to ensure that httpd updates do not bite me in the future? Do I really have to run mod_proxy whether or not I need it?

I have a small problem on my Compaq Evo Centos 5.4 web server. The web server runs just fine, the problem is it fails to restart from a power outage. Simple edit the BIOS. No! For a reason I can't think of the keyboard stops working after a few key strokes following the F10 to enter BIOS setup. Then its a power cycle. If left to BOOT the PC and keyboard are fine. After hearing about viruses which get to the BIOS I will ask can NIX get that far so I can adjust the Power ON?

I made a software RAID 0. It works fine, but when I add it to fstab and reboot the server, I can't restart the server.
Code:
# cat /etc/fstab
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
LABEL=SWAP-sda5 swap swap defaults 0 0
/dev/md0 /vz ext3 defaults 0 0
When I go to rescue mode and delete /dev/md0 from fstab, I can restart, but I get this when I try to mount it again:
Code:
mount: you must specify the filesystem type
So I try to make it to a ext3
Code:
# mkfs.ext3 /dev/md0
mke2fs 1.39 (29-May-2006)
mkfs.ext3: Device size reported to be zero. Invalid partition specified, or partition table wasn't reread after running fdisk, due to a modified partition being busy and in use. You may need to reboot to re-read your partition table.
#fdisk /dev/md0
Unable to read /dev/md0

I have a Dell precision 380 (system specs can be found here: [URL]. My system is set-up in dual boot configuration with Windows Xp x64 on one side of my HD and CentOS 5.3 (64bit) on the other. My system came with 2Gb (2 x 1Gb) of RAM and I recently wanted to upgrade. I bought 2 x 2Gb ELIXER DDR2 667Mhz RAM. I carefully added the new sticks to my motherboard, booted up windows via bios which noticed the new RAM was present. All seemed well.
However, on rebooting the system and entering the CentOS boot phase, after the boot phase (eg starting program... [ok] etc) but before the login screen my screen goes black / blank. My system has an ATI FireGL v3100 graphics card, I checked out the technical info on this and it should be ok on 64 bit linux. (See: [URL])

So this very (for me) important little package fails me once again. But this time it refuses to restart/start
This is the output:
Setting up openssh-server (1:5.3p1:-1)
Restarting OpenBSD Secure Shell Server: sshd: failed!
/dev/null is not a character device!
invoke-rc.d: initscript ssh, action "restart" failed.
[Code].....
The error is within the /etc/init.d/ssh script. ("error")
This is in squeeze so I can only blame my self, but.. This is one of the packages that fair and square should not fail to install/update/start/restart no mather what!

I'm running CentOS 5.3 64bit and from the get go I've had problems with the Apache server.More specifically, on what seems to be a random occurance, the apache server stops to respond.The process is still running, but nothing happens with it, and it is not responding.The /var/logs/httpd/error_log is blank for the occurance and only shows an entry after I give it a restart.So I'm a bit confused about what is going on.With that said, I need to make sure the httpd is working one way or another.I don't want to force a restart service every 10 minutes as this seems a bit too much.However, I do want to have the following:
run a crond every minute to do:If it fails, then do service httpd restart (and log the failure and restart to a file and email me a message).Any pointers on how to do that?It ain't the pretty solution, but it will save me from a very angry user until I'll figure what is the real cause for this failure.

I'm running VNC Server on CentOS5 on a brand new installation, this is for some of my students to use specific software via VNC on their machines from home that they otherwise don't have access to on their Windows machines. This has been working fine on our previous server for a few years but the hardware is now outdated so I have upgraded and put a fresh install of CentOS 5 on. This works fine for about 24 hours and then eventually one of the session ends up freezing where the user then can see everything on their session, the cursor can move but they cant click a single thing.

I have a Toshiba A205 S5804 laptop that had Vista Home Premium installed. Tried to install Centos 5 (2.6.18-8-el5) and when I went through the install process, X Server failed to start so I had to go thorough the command line install. Once the install completed, it only booted to console.
The default resolution for this laptop is 1280X800 but I dont know if that is why or not. if anyone has a clue about my issue, please let me know.. I really dont want to install windows.

I seem to be having an issue with iptables, every so often the server starts loosing packets and then goes off completley, if I manage to login to ssh I can stop iptables and this resolves the problem, however it keeps doing this. Is it possible to stop anything being added to iptables?

I've recently installed Proftpd to host for someone for a couple of hours.
With the default config it works however when taken the comments out and edited for anonymous, proftpd fails to start
This is the default config file which works if you have a user and password for my machine, but anonymous wont work (when the comments were removed).

I have a CentOS V5.3 system with a single 30GB HDD having about 21 GB of free space. I added a 40 GB HDD with a single ext3 partition. After reboot, the free space still reads as 21 GB. I ran the LVM GUI, and added the volume to the LVM group 00; no change to the free space after reboot. I ran the LVM again, removed the volume from the group and created a new group for the volume; still no change after reboot. I am clearly missing a key operation.

Apologies if this was asked before -- I have googled the last bytes out of my Firefox but fail to find anything helpful. Here's my problem:I have a foomatic hpijs cups-driver for a HP Inkjet (Non-PS printer) installed. Printing from UNIX-hosts works. I have cups configured not to allow raw-printing (/etc/cups/mime.types: #application/octet-stream, /etc/cups/mime.convs: #application/octet-stream).I have now installed samba-printing, the cups PS-drivers plus the Windows PS-drivers are populated to /etc/samba/drivers/W32X86/ and get pushed to the WIN-Client.Problem is that when I print from a WINXP client, the printer outputs heaps of Postscript-text instead of my page.I have tried to debug this a bit but fail to find anything really useful. My observations so far:
- The samba-pushed HP_Photosmart_3300.ppd (in both /etc/samba/drivers/... and in the resulting dir on the WINXP client) reads:
*cupsFilter: "application/vnd.cups-postscript 0 foomatic-rip"

I'm using rsync to create a mirror of the data files on our main server every day. I've looked at the man page, and can't see it; can I get a listing of the files that have been changed on or added to the mirror when it's completed? Can it just log what it's doing to a file?

I am having problems with getting the drivers to work for a geforce 9500gt.To get started Im working with a fresh install of 8.10, and I have successfully installed the driver package for this card from nvidia's site, version 260.The problem comes after I restart the computer. It fails to load. I am able to install the driver and start X and it works greatI can even restart x and it still works. but as soon as I restart the computer it doesn't load. I then need to reinstall the driver. I am curious if anyone has an idea of whats wrong here? I am wondering if it's a possible xorg.conf problem so I will post that below.
xorg.conf file
Section "ServerLayout"
Identifier "Layout0"

I have observed a problem twice now with Apache trying to restart but hanging somewhere in the process. This happens after a power failure; the machine comes back just fine, but not the web server. The machine is on a UPS, but occasionally it runs out of "juice" before someone can get to it (we have a generator for emergencies). When this happens, a ps indicates about three processes running that are trying to start Apache, but they just sit there - this time for three days since the power failure was on a Friday. I can fix this by killing those processes and doing an Apache restart - but that takes human intervention, which is not acceptable.
I suspect this may have to do with SSL, since when I do a manual restart it asks me for the SSL password. There must be some way around this so the system can recover on its own. This system's web site runs under SSL since it maintains medical information that must by law be protected. But it also could be life-threatening to someone if the system can't come back and as a result a person can't get help.
So I would appreciate some guidance as to what I could change that would allow for system recovery without intervention. I'm happy to provide any configuration file info, if you tell me where to look.

I have a Toshiba Satellite A135 with a built in Atheros 802.11 b/g wireless card. It worked perfectly up until i upgraded from Fedora 12 to 13 but now it quits working and when i go to the terminal and type service network restart I get this:
[Nemesis@Nemesiss-paradise ~]$ su
Password:
[root@Nemesiss-paradise Nemesis]# service network restart
Shutting down interface eth0: [OK]
Shutting down interface wlan0: [OK]
Shutting down loopback interface: [OK]
Bringing up loopback interface: [OK]
Bringing up interface eth0: Error: Connection activation failed: Device not managed by NetworkManager [FAILED]
Bringing up interface wlan0: [OK]
[root@Nemesiss-paradise Nemesis]#
And I am not sure what to do, I can get the wireless working again if I completely shut my computer down and restart it. I am running gnome.
