I am trying to configure a 2.6.18 kernel and I cannot get it to read the raid5 module since my system is utilizing a software RAID5.
Whenever I build I receive the following error:
[root@localhost linux-2.6.18.8]# make install
sh /root/kernel/linux-2.6.18.8/arch/x86_64/boot/install.sh 2.6.18 arch/x86_64/boot/bzImage System.map "/boot"
WARNING: No module raid5 found for kernel 2.6.18, continuing anyway
I have tried versions 2.6.18 and 2.6.18.8 and both give me the same issue.
I have CONFIG_MD_RAID456=m in my .config so the module should be getting configured.
I tried ignoring the warning but when I boot up my system in 2.6.18 I get a kernel panic error, could not sync. (I'm guessing because it doesn't have the RAID module). Everything works fine when I boot up in the 2.6.9 CentOS kernel.
Now I'm a little new to RAID5, I've always used RAID10 or RAID1, but I am looking into RAID5 for my new server.
Tell me which you think would be more beneficial, I know RAID10 is faster for writing and copying which is what is needed for SWAP but I also know that RAM is a lot faster than SWAP.
8GB RAM 2GB SWAP Partition 4x250GB RAID5
7GB RAM 3GB SWAP Partition 6x250GB RAID10
or
8GB RAM 2GB SWAP Partition 3x400GB RAID5
Is 3 drives or 4 drives faster in a RAID5? I know 4 drives would probably read faster but would copying and writing be slower?
My server is with Supermicro PDSME+ and 3x500 GB WD Raid Edition with one hot-spare.
When I migrated from RAID-1 to RAID-5 the performance droped dramatically. I have been reading different posts on internet that suggest to force HDD to work on 1.5 GB/s. On Supermicro support page there is a similar issue and support staff explain that ICH7R do not support SATA-II.
When I review specification on their web site, they typed that MB support 3.0 GB/s.
Does anyone have a similar server with a similar issue?
We are expanding our photo sharing business and are revising our Unix-based server architecture. We're looking to develop a standard server configuration so that we can easily add servers when necessary.
Our ISP has recommended a configuration with mirrored web servers and mirrored RAID5 NAS boxes. I've read about Google's server architecture which consists of identical mirrored servers; when a drive or part from one of those servers goes down, data is served from the mirrored servers and the bad machine is repaired or replaced.
Comparing the two architectures with similar storage sizes, the overall cost of the hardware itself is about the same, with the identical mirrored machines being slightly cheaper. The monthly co-location fees (rack, power, etc.) are higher for the NAS solution.
I'm interested to hear your thoughts and experiences with similar solutions. I know the web/NAS solution is popular, and it's probably the one we'll go with, initially at least. Has anyone here implemented a Google-like identical mirrored server solution?
/dev/md0: ext3 mounted as / for all of the software RAID partitions.
I was left to believe this would create redundancy as long as only one drive is removed from the array. Although when I unplug any of the hard drives (one at a time) I get input/output errors and when I try to reboot I get kernel sync errors.
What exactly am I doing wrong when trying to create redundancy? I know that SDA contains the /boot/ partition so it wouldn't boot without that but even if I unplug B,C, and D it still can't sync.
I didn't know if it should go in here on in Web Hosting.
One of the prospective hosts I'm looking at for shared hosting uses a phrase I'm not sure about what it means and the sales person I spoke to didn't know, either (and he tried to fudge it, which is worse than admitting you don't know.)
Anyway, one of the phrases used that I haven't seen anywhere else is that they have php5 "as a module" and I'm not sure what is meant by that. Each account is running a stand-alone instance of php? php5 is a module that's installed upon customer request?
Trying to troubleshoot an exploit where the code redirecting people to exploit sites is not in the website. I think a module is being loaded dynamically, but I am not seeing the entry point in the access logs. I restart httpd and the problem goes away temporarily.
Anyone see anything fishy?

I would like to know is there any module for Apache which can collect information like who is surfing our website and how many pages they have accessed in last one hour. I know awstats or webalizer can do this but i need some thing realtime on apache level.
I found a script that updated php to 5.5, however it's only enabling me to run it as a CGI script, if I want to run PHP an Apache module, it's still only 5.3. How can I upgrade the Apache version?
I've bought a basic unmanaged VPS, purely to learn things from it. The best way to learn imo is to hammer the hell out of things, break it, then try to fix it. Anyway, I think I'm part way there, pretty sure I've broken something
When I start the consoleSSH I get this at the top:
I have nothing to do with it. Just passing it along.

I have 5 servers spread out in different locations running Fedora Core, Webmin, and OpenVPN.
My most recent one I signed up with on here and for 2 weeks I have been doing various things to speed it up such as remove ipv6, change the dns servers, etc. and rebooting after making such changes.
Things were working properly and the server was rebooted last about 3 days ago after installing OpenVPN and Webmin. Yesterday afternoon the server suddenly stopped responding and dropped its VPN connections. I created a ticket with my hosts support center and they told me that the network module was uninstalled.
Is this possible? I have NEVER heard of any software uninstalling a network module and even more so suddenly stopping the service to uninstall it without a reboot?
Did my host just try to screw me to get a reimage fee on their cheap server?
Will the APF firewall work without the "ip_tables" module? I contacted my server management company and told them my previous tech said enabling ip_tables module on any VPS on our system would cause a kernel panic. Their response was to install APF on the VPS in question and not enable ip_tables, saying it should still block IPs and ports that aren't supposed to be open. Is this true? Or am I getting the runaround?
I'm on a shared host that allows shell access. We need to install a PHP module -- they say we can, but they won't do it for us. Can anyone explain how we would accomplish that?
A customer recently asked me to install the ImageMagick wrapper for php, however I am having some difficulties getting it to show up in my phpinfo.php page.
would I be able to install any additional php modules NOT listed in Cpanel (example memcache, ffmpeg, etc.) on a Cpanel server? If possible, how do I do it?
I have a server running Apache 2 with PHP as an Apache module. There are a few php scripts that use lots of cpu when they run and have lots of hits, but Apache is still running fine and pages and php scripts load pretty fast. I was just wondering if running PHP as fastcgi would use less cpu or make php scripts load faster.
I recently signed up with a reseller hosting account who told me that if I want to automate the domain registration with my WHMCS. -
"If you want to integrate it into WHMCS however to automate it, use the domain registration module "Net Earth One" "
now I consider myself a techie and can usually find stuff out on my own but this is killing me. I can't find one documentation on how to this "integration".
Where do I find this "module"? do I download this then install to WHMCS?
