Server :: Two RHEL 5.4 Clusters On Same Network Segment?
Jul 23, 2011
Two years ago, I have set up two node Active-passive cluster on VSphere 4.0 and it is in production ever since.
I've tried to setup another cluster for testing purposes on the same VSphere, and failed. And what is interesting is that those new two nodes came up with cluster.conf of the production cluster, even though I did not try to bring them in the existing production cluster. I googled a bit and found something stating that two different clusters might behave strane if on the same network segment. Question is, did anyone try to create two different clusters on the same hardware, or on the same network VLAN?
I will do some more digging after weekend, and get back to you.

I have a RHEL 5 Server dedicated to web hosting. HTTPD 2.2.x.x is running on it with PHP and MySQL. The machine is not a server system (hardware wise, a C2D 2.66 with 2GB RAM and 2 x NICs). I have a CIR Fiber link with a pool of live IPs. The machines including this web server is plugged into a switch which has all the live interfaces and is separate from the LAN switches. The problem i am facing is that, when ever this web server is plugged in, the traffic on live switch is choked. Internet slows down to a halt (as live interface of proxy is plugged in this switch. DNS stops resolving name due to time outs. Mail delivery is slowed and the mail ques pile ups. The moment i get this machine of the switch, all the traffic becomes normal. Therefore i have deduced that this is the faulty server. I do not know if this server is hacked and working as a bot or it is a mere hardware problem(faulty LAN Card).

is possible to edited the default RHEL CD to have it automatically install RHEL based off of a kickstart file that I will store locally on the CD. My plan would be to put a cd in a server and have the OS automatically being installed.

I have a database server running RHEL 5.1 32 bit that suffered some catastrophic failures about 6 months ago. We were able to patch it back together and keep it running, but now the manufacturing site it supports is going to shut down for two weeks and I would like to replace it permenantly. Does anyone have any guidance for that sort of thing? I'd like to have the new server up and running before hand, basically changing the hostname/ip and restoring the databases only on conversion day. I've done this in the past with HP UX - Red Hat conversions, but this is my first red hat to red hat move. Any advice or shortcuts?I forgot to add the other wrinkle. The new server will be running 64bit linux.

Subnet : 255.255.255.192
Gateway : 172.16.152.191
Primary DNS : 172.16.0.1

but after this setup when i restart my network #service network restart while bringing up the eth0 the following message is displayed before [OK] - RTNETLINK answers : Invalid Argument now it seems either this setup is wrong or not sufficient to set up the connection, whenever i try to ping 172.16.0.1 it showing connect : Network is Unreachable

I am dualbooting Karmic, windows 7, and fedora. When I boot, Grub2 will boot everything but Windows 7. Instead it says:
Code:
reloc offset is out of the segment
abort.
I've tried reinstalling and updating grub2 and I also tried grub. It wasn't a problem until I put Lucid on a 4th partition that's always been there. I let lucid install grub2 and after that windows didn't work, but I got the same error when I reinstalled it from karmic. I got a different error from grub (that I don't remember), but I wasn't positive about the configuration so that may have been my fault.

I see from dumping executables that seg selector 0x10 is assigned to my stack segment and to my data segments (.bss .data COMMON). The code is using 0x08. My question - how can I control this? I've looked at all the command line options and don't see it. I have a different program that uses 0x10 for code and 0x18 for data. I note that the second program has i386 in the architecture field in the linker script, whereas the first one referenced has i686. Is this what causes the difference? I understand that this architecture field triggers something regarding a library named BFD - is this where I should look? If so, where do I find it? I am runnig fedora. Is there a way to control the association of sections in the linker script with segment registers? I can set up segments in the gdt and can asign them to segment registers. I can - when writing in assembler - assign code to a section. I can relate a segment in the gdt with a register.But I dont see how to tell the section which segment register it is associated with Finally I see that the gcc compiler decides - based on how I initialize a variable - whether to put it into bss or data or COMMON. Do I have any control over this?

I have an harddisk which is old, since many years >10 years, and I recall I crashed few clusters using windows programs which were old and harddisk stuffs doing. So the pc lives with bad clusters, this pc lives very well since many years.Question, the pc has woody debian, which let us to install and exclude bad sectors during install. Bad clusters was an usual thing in the past, but today not anymore.Unfortunately debian squeeze installer coders had the good idea to remove the " bad cluster checking " before installing debian, during install (cdrom netinst).

I have had a strange experience in upgrading to Ubuntu 10.10 on a Dell Inspiron 1545 also running Vista. I was upgrading from a Ubuntu 8.04 that I thought would be worth reporting/sharing in case others have had a similar experience. last week I upgraded to Ubuntu 10.10 using the live cd. Everything seems have gone smoothly. I could log in and out of ubuntu. After logging into Vista and logging out, the next time I tried to start the machine, there was a 'segment offset error' with the boot loader and there was no way of rebooting into anything except to use the Ubuntu live CD and go to a terminal and reinstall the bootloader. The same thing happened after logging in to Vista- this seemed to mess with the boot loader. Logging in first time was not a problem.
Yesterday I started again, wiped out 10.10 and re-installed ubuntu but version 10.04. Logging in and out of Vista is so far ok and I have not had any problems. I do not have an obvious logical explanation to the sequence of events unless there is a problem with the boot loader in version 10.10.

Our application uses a dynamically loaded shared object library (codec library) to compress and decompress audio streams.
There happens to be several static and global variables in this shared object library. Hence it is not possible to process two interleaved unrelated media streams using this shared object codec library because each stream corrupts/changes the contents of these static/global variables.
Is there a way through which a context save (save contents of data segment of shared object) and a context load (load previously saved contents of data segment of shared object)operation can be performed on the shared object library. This way the context for each media stream can be saved and loaded before and after processing the "other" media stream respectively.

Based on what I understand, eth0 goes to monitoring and the other 2 ethernet cards go to FE. I am not an expert in system administration but would like to know if there is any issues with the above settings/configuration (in fact, im also looking for what do they infer and what is the settings?
