I bought two Dell R200 because they was extremely cheap.
My target is Open Source SAN with active/passive setup.
Now i was wondering what RAID-level I should go for.
I will use 1TB SATA-II disks.
1) RAID-1 in both servers and mirror each other with DRBD.
With this setup i have like double RAID-1 so i lose lots of disk space.
4 disks -> 1TB
2) No-raid at all and i will mirror data with DRBD.
4 disks -> 2TB
Then there is change to go for RAID-5. Theres enough space to put third disk in that case
3) RAID-5 in both servers. Mirrors data with DRBD.
6 disks -> 2TB but more performance.
But in every setup i lose space more then i would like to.
Actually i dont need space more then 1TB, but i would like to get best possible redundancy and most space available i could.
Also need to remember that those servers does not support hot-plug HDs so in case there is disk-failure i need to be able to shutdown one server and iSCSI should still be up and running.
Of course theres change to make it active/active.
I was thinking that if I go for the RAID-5 I will make LVM-VG on both nodes (san-vg1 and san-vg2) and use it 50/50.
In case of fail both VG's will be used from working node.
Im going to use Debian Lenny I guess..
I was looking for OpenFiler because of the GUI, but im familiar with Debian and have always done everything from cmd.
if anyone replaces a commercial program with their own open source as for eg what Friendster did. For Netscaler, any open source development that are close are similar to it?
I have been getting multiple emails a month for a service which I have never purchased.
The information they have harvested off the internet (since I know where they found it) and have obtained solely for use in attempting to charge me is- Invoiced To Steven Crothers 12345 Main St., Detroit, MI, 48021 United States
Which is completely obvious that it is fake.
I respond to EVERY invoice with a cancelation request, yet the tickets that get opened in the WHMCS billing panel get deleted a day later, however I have tickets in there that I have opened by use of the ticket insertion form that have stayed - none of which were ever answered.
The latest ticket information- Department:Billing And Invoicing Date:09/10/2009 10:05 Subject:The Second Time... Status:Open Urgency:Medium
It's still open without a reply.
I have put tickets into their Kayako system as well (They have two support systems, I would assume its due to poor management of their company). One of which was answered, with simply the output of `uname -a` on some server somewhere with my name as the hostname.
I than have attempted to reach anyone via livechat at [url]they constantly tell me that I am not allowed to speak to anyone until I pay my bills up to current (now remember, I have NEVER ordered anything from them, they don't even have valid information on file). Just tonight I demanded that I required to speak to a billing agent or I would be pressing harrasment charges against them for the 23 emails I have recieved in 3 months from them trying to extort money from me. They than banned me from their LiveChat software.
I have no idea what to do at this point, they are just sending me bills every month. I mark it as spam, but its frustrating to have a company trying to extort money from me on a very regular basis.
Is there any Open source backup software available for web hosting companies? I have a few shared hosting servers and a few dedicated servers and I want to setup a backup server for the backup of the data and config files of the servers. Please give me the names of some good open source backup software.
I own a small tech firm, mostly in business to support the customer with basic repair and upgrade. In recent year, more and more of my SMB customer ask me about the hosting service of the CRM or CMS.
The question I have is, although the open source tool, such as SugarCRM and Drupal is free of charge, but will it be free for some one like me to offer the service to my customer, either the same or customerize it a little bit.
And if it can be done, what kind of precaution I need to take, so I will not be involved in the copy right battle later on.
Thought this might be of interest to folks on WHT. We put together a solution using Nginx ( Engine-X ) to do Global Server Load Balancing. This solution lets you do GSLB without having to fork over $26k per site to F5 or Foundry.
Thought it would be of interest to both end-users as well as dedicated hosting providers who might want to make it into a service (eg. sell a dedicated host in Europe and the US as a group, with the solution pre-installed).
The entire project, including relavent configs is available for download in the latest ( issue 6 ) FREE issue of o3 magazine (o3magazine.com)
here is what I seen when I installed kernel-2.6.20-1.2948.fc6.src.rpm
rpm -ivh kernel-2.6.20-1.2948.fc6.src.rpm 1:kernel warning: user brewbuilder does not exist - using root warning: group brewbuilder does not exist - using root warning: user brewbuilder does not exist - using root ########################################### [100%] warning: user brewbuilder does not exist - using root warning: group brewbuilder does not exist - using root
then when I ran: rpmbuild -bp --target=$(uname -m) /usr/src/redhat/SPECS/kernel-2.6.spec
I seen this error: + Arch=x86_64 + make ARCH=x86_64 nonint_oldconfig In file included from /usr/include/sys/socket.h:35, from /usr/include/netinet/in.h:24, from /usr/include/arpa/inet.h:23, from scripts/basic/fixdep.c:117: /usr/include/bits/socket.h:310:24: error: asm/socket.h: No such file or directory make[1]: *** [scripts/basic/fixdep] Error 1 make: *** [scripts_basic] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.93770 (%prep)
I need to have this installed to get a app installed etc... suggestions or ideas? thanks
I'm under the gun, and looking for a source for 40km and 80km XFPs (e.g. Finisar, Agilestar), who keeps them in stock and at a good price. I prefer to work with vendors who are subject to US law.
Website source is a great hosting company! They host up to 8 domains for $107.00.. They have great customer service and they offer 24 hours online support.
Which PHP encoder do you all suggest out of Ioncube and Source Guardian? Or possibly another if you know a good one. I checked out Zend Encoder, but its expensive as hell. Currently I'm thinking about Ioncube. I know the majority of web hosts have ioncube loader installed, but I'm not sure about source guardian.
if a program is compiled and installed (configure -> make -> make install) with a --prefix pointing to an empty subfolder, then would removing it be just a simple delete the folder and it's contents action ($rm -fr subfolder/).
Ok so lets say I was to install php from source with a complile prefix flag set to /usr/local/php
Then all the binaries and configuration files are set within the directory (php/conf , php/bin). If I want to delete the php installation then I would just remove the /usr/local/php directory, No?
Thinking very seriously about revolutionizing the ISP market, starting with WiMax-based service in the Texas hill country, as I'm tired of the basic monopoly outside of town and the near-monopoly in town for halfway decent access. Anyhow, I plan to get Cogent FastE for the main backbone, however I know I need something else in case some spat starts between Cogent and someone else (Level3, France Telecom, Telia). Internap is in Austin I know, but Cogent has a POP in San Antonio which is much closer to where I'm going to deploy the network. Any options in the Internap price range for maybe 20 Mbit to start? Yeah, I know that the price of the "backup" connection may be more than that of the main line, but if people want their WoWwebetc. I want to live up to that promise.
Thanks in advance. If I gotta use Internap I'll do that, but again that means setting up a link in the opposite direction to what I'm thinking right now. The ultimate answer would be something relatively inexpensive (sub-$100 per Mbit with 20 Mbit commit) relatively close to one of Cogent's San Antonio data centers. Cogen't bandwidth deals are awesome, but with one peering argument per year or so a backup seems needed.
We have a large number of the 2U SC832 and SC833 cases from Supermicro that have been real workhorses over the years and some have had various motherboards in them as time went by. All of them are 5-7 years old and we would like to keep using them, but are concerned about the fans in the power supplies getting worn out and failing. Anyone have the source for good high quality fans that would work in these 400 and 550 watt single power supplies?
Anyone have an idea of what the normal life of one of these power fans is? All of them have been in good datacenters from there first use.
Since I know there are a lot of Supermicro users on this forum I figured this would be the best place to ask.
My server running and update CentOS 4.4. In the last hours lot of spam are being send form my server to the world. I'm unable to locate the source. Sendmail is define to relay localhost, and it seems that the source is local!
It seem that all the email are send from apache@mydomain.com to user@mydomain.com Sendmail is configure to accept for local delivery mail for domain mydomain.com Here is trace of spam session:

It seems the spam message BCC contain a lot of victims address, that not from mydomain.
Is some one connect form outside and spoof 127.0.0.1 ?
If it local process, ho do I locate it?
I scan /tmp and my web server root for suspicious file and didn't find nothing!
how many players you would estimate the following server could handle running Counter-Strike Source dedicated Server?
Dell PowerEdge 1550 1U Rackmount Server 1Ghz P3 Processor - 1GB RAM 2X36Gb U160 SCSI Hard Drives in RAID1 for redundancy Windows 2000 server Network connectivity is 100mbit in a London DC.
Of course its not possible to give a 100% accurate figure however i would like a rough estimate prior to me purchasing this machine.
