I have a problem on my dedicated server, the boot is at 99% but i am not sure
how to fix this problem.
The server runs centos 4.5 final.
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 228G 17G 199G 8% /
/dev/sda1 31M 29M 492K 99% /boot

I used WHM to mount a spare partition and when the machine next rebooted, it give this error, nothing has been put on the disk as of yet.
Has anyone here been successful in doing a usb boot of windows xp & win2k3 server?
View 3 Replies View RelatedI've supposedly set APF firewall to start at boot time, by doing something like:
chkconfig --levels 2345 apf on
However i have my reservations to weather it is actually starting, its set to block port 80, after boot if i try and access it, the connection will get refused straight away, however if i go and manually start APF then try and access again, it will take a while, like its ignoring the connection attempt (which is good).
How could I check if APF is actually running?
How We can set a shoutcast servers to starts automatically on boot/restart/etc?
View 14 Replies View RelatedI'm trying to put together a new 1U rackmount server that I'm intending to colocate (my first server of my own). Here are the details:
11-152-087 CHASSIS SUPERMICRO|CSE-512L-260B R
13-182-120 SERVER_MB SUPERMICRO|MBD-PDSML-LN2+
22-144-417 HD 250G|WD 7K 8M SATA2 WD2500JS
19-115-029 CPU INTEL|C2D E6750 2.66G 65N 4M R
20-134-337 MEM 1Gx2|KST KVR667D2E5K2/2G R
The stock CPU fan is obviously too big to sit in a 1U rackmount chassis, but I've got the top off and was just trying to boot up with the OEM fan to make certain everything worked (forgot to order a low-profile fan and heatsink--they're on the way).
Well, I put everything together, and it won't boot. Upon power up, there is nothing sent to the VGA port, and after a second or two, there is a hi-low alarm sound that does not stop that seems to imply the system is overheating (the MB and chassis manuals don't mention this alarm anywhere, but the read "temperature" light on the front is red). The CPU fan runs as well as the case fan, and even if I hold a huge high-velocity home fan over it, it still won't send any signal to the VGA monitor or POST.
I've checked that the power connections are good, the fans are seated properly, the memory contact is good, etc., and all I get is this hi-low chime every time I try to boot up. I think it's either a bad MB or CPU, since I can't imagine that the CPU is overheating with the heat sink and CPU fan.
Perhaps I've screwed something up, but the next issue I have is trying to figure out what could be causing the problem so I know what to return or replace. Is it the CPU? MB? RAM? Power unit? How can I test any of these without buying another set and possibly frying those?
I figured maybe some of you might have some ideas. I've built several computers over the years, but this one has me completely stymied.
This is probably the wrong location for this thread but I am unsure which section it is best located at.
I have 2 hard drives - 1 has XP pro installed (master drive) on it and the other is blank and set to slave. On the blank one i intedn to install Red Hat linux.
How is the best way to create a dual boot with these machines if each hard drive has one O/S dedicated to it.
I'm not sure exactly how to phrase the question. But, I'm researching how to PXE boot a server without having a DHCP/PXE server in each vlan.
Scenario: Datacenter with dozens of servers. 1 VLAN per server. Cisco switches and routers. Each server has a serial console available for remote management (OS and BIOS are configured for serial console). If an admin wants to re-install OS, they should be able to reboot the server and tell the BIOS to initiate a PXE boot request. A central install server is available to provide the DHCP and PXE boot images.
Has anyone tried this? I have been reading about the 'ip helper-address' for Cisco to relay DHCP requests. Interested in hearing about real-world setups. Or is there a better way to accomplish remote OS installs?
We cannot figure out why our dedicated server will not boot to the correct kernel. I've removed all other options from grub.conf but it's still booting to the default CentOS setup.

I've got Centos 4 and I'm wondering what's the best way to cleanup my /boot partition?
Tried to do a yum update tonight and it included kernel, amongst other updates that belonged there so it stopped. I've googled around for commands to run and whatnot, but no go... or I just can't find it... if I had to clean it up I have an idea already about what to do, but I want to ask for advice first to see if there's an easier way.
so, how do people here clean up that partition?
I have a NAS to mount but it disappears on every (re)boot. How do I automatically mount it on boot?

Just asking, where should I usually install my boot loader:
/dev/sda - master boot record (MBR)
-- or --
/dev/sda1 - first sector of boot partition
My partition for /sda1/ is /boot 100MB
am running CentOs with whm/cpanel and am whenever i reboot my server all sites that required mysql show erros ( can't connect ) it resolves by manually in the web host manager restarting mysql.
I already tried
chkconfig mysql on
then rebooted and the error persists,
I have an old server with only IDE and SCSI connectors on the mobo.
However, I have only SATA drives and no IDE available. I consider to buy an entry level PCI SATA adapter card. What do you think ? Can I install and boot Linux directly from it?
There is no raid involved.
I have insalled windows in hda and linux on hdb, but after I installed grub loader it is coming to grub prompt as this:
grub>
someone suggested to do the follwing comand
root (hd0,0)
kernel /boot/vmlinux....
boot
I am not sure about this this line:
root (hd0,0)
What exactly trying to do?
Right after booting from HP-UX PA-RISC, Tomcat refuses connections.
Trouble Description:
No startup error messages are logged and processes are up and running.
Checking /etc/rc.log:
----------------------------
Starting Tomcat server
Output from "/sbin/rc3.d/S998Tomcat start":
----------------------------
Using CATALINA_BASE: /opt/mediation/Tomcat5.5
Using CATALINA_HOME: /opt/mediation/Tomcat5.5

Using JRE_HOME: /opt/mediation/java/jre15_15002
/opt/mediation/Tomcat5.5/bin/catalina.sh[233]: touch: not found.
----------------------------
If Tomcat is manually stopped and restarted, it accepts connections.
I have set up Windows Small Business Server 2003 and was testing it over the past week. Everything has been going well and yesterday it requested to install an update (not to sure what it was now) and soon after the update was installed a restart was required.
After the server shutdown and tried to restart the system will not restart.
The machine powers up and then I am faced with a blank black screen (no load bar nothing). The monitor led light flashes from green to orange then to a static green light after the Dell splash screen.
I can load up into safe mode although I do not know how to work out what is wrong. I am guessing the update has caused the issue, possibly a boot sector needs repairing. There are no new additions to control panel -> install/remove programs which i believe is where all updates can be uninstalled from.
I backed a system up with rsync, and just used rsync to copy it into a new machine... I just backed up / to my home directory on another machine, and then 'extracted' it to / on the new machine.
But now everything (and I mean everything) is owned by "matt", my user on the intermediate machine. I rebooted the system to get it to boot the new stuff without realizing this, and now it's not booting... Since /etc/passwd, /bin/bash, etc. aren't owned by root.
Any tips on where to go from here? As I said, it's a brand-new machine (VM, actually: even better!), so re-imaging is a solution, but I'd still have to copy the data back over. Reinstalling is a pain, though, so if there's a simple fix, I'd prefer that. I've got pygrub installed as a boot manager for the VM, but I can't for the life of me figure out how to get into single-user mode. (Nor am I sure that a "cd /; chown -R root" will have the desired effect?)
After installing Kernels seems /boot is boing to be full soon. Which files can be safely deleted ? Mean lets say to keep the latest Kernel and previous version:

2.) the command line to boot a VM linking to its config file
I have a problem about my server, after it is unsuspended, it is not actually working anymore.
I got kvm access, when i try to choose harddisk for boot option it says INIT: No inittab file found
and asks for runlevel : I tried 1,2,6 but none of them are working.
I am choosing the rescue mode than it is asking me for rescued login which i don`t know
I've exausted my self attempting to load on a boot image to the management blade for a project that i'm doing with a few friends.
I just bought this Foundary *off ebay of course* and who ever had it last removed the image! I mean I cant even get into the primary or secondary. I tried booting from tftp, but everytime that happens, the switch just restarts and then doesnt boot up again. This is what i'm getting.
Code:
BOOT INFO: RESET ANY
master arbitrate : become primary arbitrator.
BOOT INFO: Become active CPU module
M2 BI Boot Code Version 06.05.00
Enter 'b' to go to boot monitor ...
BOOT INFO: load from primary copy
BOOT ERR: bad code image header
BOOT INFO: load from secondary copy
BOOT ERR: bad code image header
BOOT INFO: try to boot from bootp server
bootp timed out, bootp-tftp process aborted!
BOOT ERR: bootp failed
I currently have the B2R07601b.BIN image, just I dont know how to load the file onto the blade via tftp or any other method.
I've software RAID installed with one SATA and one ATA/IDE drive. It is a combined controller so I had to add noprobe=/dev/hdc to the kernel boot line. Now the disks are named /dev/sda and /dev/sdb. There are four partitions, /dev/sda1 and /dev/sdb1 are the /dev/md0 root partition and then /dev/sda2 and /dev/sdb2 are the swap partition.
First when I removed one drive I just came to the grub command line..
Then I tried to do this in grub to make both drives bootable:
grub>device (hd0) /dev/sda
grub>root (hd0,0)
grub>setup (hd0)
grub>device (hd1) /dev/sdb
grub>root (hd1,0)
grub>setup (hd1)
grub>quit
Now it looks like normal when I get to grub apart from that the background of the boot screen is black instead of blue and then the computer just restarts when it is supposed to start/boot the system.
Everytime it boot up, desktop gdm will be loaded. I need to go in straight to command line during boot up with some sort of shortcut key.
View 2 Replies View RelatedI am in a somewhat complicated situation... I wanted to order a custom server with hardware 3Ware RAID controller but after over a month of waiting I was told the HW RAID controller, as well as any other 3Ware controller they tried, does not work with the motherboard used in the server from Fujitsu-Siemens and that they simply got a reply from FS that the controller is not certified to work with their motherboard.
So although I'd prefer a HW raid, I am forced to either choose a different webhost or setup a software RAID. The problem is, I haven't done that before and am somewhat moderately...scared
I have read a lot of the info about SW RAID on Linux that I could find through Google but there are some questions unanswered still. So I thought that perhaps some of the more knowledgeable WHT members could help me with this problem...
The server specs will be:
Core2Duo E6600 (2.4Ghz), 2GB RAM, 6-8x* 250GB SATA II HDDs, CentOS 4.4 or SuSe, DirectAdmin
* I prefer 8 HDDs (or actually 9) over 6 but I am not sure if their server chassis can hold that many HDDs, I am awaiting answer from them. They don't have any other drives beside the 250GB ones so I am limited to those.
The preferred SW RAID setup is to have everything in RAID 10, except for the /boot partition which has to be on RAID-1 or no RAID I believe, plus one drive as hot spare (that would be the 9th drive). I am quite sure they will not do the setup for me but will give me access to KVM over IP and a Linux image preinstalled on the first HDD so that I'll have a functional system that needs to be upgraded to RAID-10.
How do I do that? The big problem I see is that LILO or GRUB can't boot from a software RAID-5/10 so I will have to mount the /boot partition elsewhere. It's probably terribly simple...if you have done it before which I have not. I have read some articles on how to setup a RAID-5/10 with mdadm (e.g. [url] ) but they usually do not talk about how to setup the boot partition. Should it be setup as a small sized (100-200MB) RAID-1 partition spread over all of the drives in the otherwise RAID-10 array?
What about swap? Should I create a 4-8GB (I plan to upgrade the server RAM to 4GB in near future) RAID-1 swap partition on each of the disks or swap to a file on the main RAID-10 partitions. The second sounds simpler but what about performance? Is swapping to a file on RAID-10 array a bad idea, performance wise?
Is it possible to grow a RAID-10 array in a way similar to growing a RAID-5 array with mdadm (using two extra drives instead of one of course)? mdadm doesn't actually even mention RAID-10 despite it does support it without having to create RAID-0 on top of RAID-1 pairs if the support is in kernel, from what I know.
A while ago i had signed up with the affiliate program of 3ix.com webhosting.
After a few months some commisiions had been confirmed insid their panel, when all of a sudden further access had been denied.
Since two months they keep on mailing lies such as the affilate manager will respond, we are working on it etc.
But now they no longer respond and it seems, that 3ix.com will be vanishing soon with more and more complaints arriving at the FBI internet fraud department.
Certainly not a host, that deserves any trust.
dnsreport(.com) displays this warning for my domain:

Although I've created an SOA in my Windows DNS Console. Whats it then?
Also, it says:

Currently using a 512MB VPS with CentOS
Anything is should be concerned about or am i not getting my full 512Mb VPS as i should be?
My opinion: Do NOT EVEN CONSIDER using HOSTGATOR.
My experience:
I signed up for their hosting on Sunday morning and completed payment for the first month using hostgators online payment system and paypal.
The payment was accepted and confirmed. An email was sent some time later confirming the account had been set up.
The email specified a user ID for cpanel as well as nameservers which I used to point two of my domains at the new hostgator account.
I used cpanel and FTP to set up the add-on domain, create some email accounts and upload content for the two domains (the same content as on the old servers which should now be shown k-free.co.uk and offshoreharry.com).
All appeared to work fine with no problems. I could use outlook to access email and the web sites were available on the new server (the old server was down).
A day and a half later, I WAS HORRIFIED TO SEE
- the emails accounts could not be accessed
- the cpanel user did not work
- Hostgator did not email me or attempt to contact me in any way to tell me there was an issue. (they had my valid mobile phone number - there are no unidentified calls in the period concerned).
- the web sites that had been pointed at hoistgator were showing a suspended message and spammy hostgator context ads. My non-spam mostly non-ads content had been uploaded to the hostgator account.
One of those domains is freeware software on a site with ZERO ADS that has never been moneterised and sometimes gets 100's of uniques a day.
HOSTGATOR WAS STEALING TRAFFIC FROM MY ad free unmonetized site and showing a nasty spammy ad page.
Not only was I rather angry but also amazed that any company would ever do this. Just think how you would feel if all your sites - pages were hijacked and showing some of the nasty ad pages.
My opinion: Do NOT EVEN CONSIDER using HOSTGATOR.
Checking my yahoo email, there was no email from hostgator saying my account had been suspended (if I hadn't checked it they would have continued stealing the traffic until I noticed).
The only email from hostgator was a request for a copy of my passport or utility bill! I am left wondering if they are really a front for an identity theft scam? I am rather unhappy that they have even my name - address - tel no - paypal email.
I obviously immediately changed the nameservers on the two domains back to the old servers. But since nameserver changes take upto 72 hours to fully propogator, hostgator could still be stealing some of my traffic now. The two sites contain nothing that any T+C I have ever seen would have any reason whatsoever to see as a problem. The two sites are k-free.co.uk and offshoreharry.com for anyone here who wishes to verify this claim.
Hostgator COULD be showing my content instead of their spammy ads - I uploaded it.
Hostgator was mentioned by a few on here and I thought them to be a big company who have a reputation to protect. Are you guys really comfortable with a company who behaves like this. Will they suddenly suspend your sites tomorrow and steal your traffic until you happen to notice?
I have requested to them that they provide access TO MY PERSONAL AND BUSINESS EMAILS on the email accounts I set up. I would also like any log data that was collected. I will report back here what the response to that (politely worded) request is. Giving me access to any email and log data that they have effectively kidnapped-stolen hardly makes amends for the wrong they have already done. Like any other victim of a common thief I may just have to accept that I lost something and will not see it again.
Additionally, search engine robots may have visited the sites and got 404s, any users who dropped by will certainly not be back, the damage caused is ongoing and difficult to fully quantify.
Hostgator did not email me or attempt to contact me (they had my valid mobile phone number). They did not tell me why the account was suspended and the trafic STOLEN. I have had web sites for 4-5 years and have never been involved in anything remotely dubious on the web. You can judge for yourself if there is any reason for them to do this [sites offshoreharry.com, k-free.co.uk]. I had sent at most 10 emails whilst testing the 3 or 4 email accounts I was creating.
Obviously I will never use hostgator or any related company.
My opinion: Do NOT EVEN CONSIDER using HOSTGATOR ... EVER.
