While installing rocks 7 cluster distribution on my server am getting error after downloading and installing the Rolls from this site
"http://central-7-0-x86-64.rocksclusters.org/install/rolls" (this is the default website but its not working now http://beta7.rocexikscluster.org/install/rolls) the error is related with python software each time the error code was different first I got an error for python was code 331, then next I got some other error's related with python 2.7 site packages, the problem is that only Rocks 7 manzanita was supporting my server(kernel is booting), rocks 6 sandwinder kernel is not booting but it is working fine on VM workstation and also it is booting with local system's, my new server is dell power edge r740, tried downloading different rolls form different website (mirror) but the result are same.

I would like to find a solution for the above issue, I hope you understand my problem, waiting for a better solution

Personally, no.

What I do understand: You successfully installed Rocks 7 but installation of Rolls (optional add-ons) failed.
I don't understand the failure symptoms, because you don't describe them.

You say "I got an error for python was code 331". I don't think that "code 331" is the error message.

You say "I got some other error's related with python 2.7 site packages" - fine but what errors?

Here is what you could do:
State exactly what you did, including the precise commands that led to error messages.
State the exact error messagess.

This will allow people to help you. Not necessarily me, because I don't know Rocks, though I might have ideas around Python.

My apologies, and Thank you for the reply, Actually I didn't saw this post so I recreated another thread (I dont know how to remove that thread), Well the reason I am not posting the error code is that I don't know that there is a community that exists for trouble shooting all linux issue, at that time I didn't think to record the error, so I came up with another installation and this time when the error was different so I just clicked the debug button and then I checked the console I have the picture but I have to create bb link or url, right now am not able to attach the files. Please have a look the below error.

"anaconda 21.48.22.121-1 exception report

Am not an expert in linux or centos, basically am an average expert in Windows. This is also a part of my Job I have to install this with cluster, without cluster centos will install and working fine with the server but when it comes with clustering am helpless, as I said each time am receiving different errors, so I will try to get the first error for you ( I think this was the first fatal error code 331 none type object for the file python.py) am not sure this is the only error because if I resolve this what kind and type of error is waiting for me, am looking forward to see. I hope now you understand partially about the issue.

This is a partial stack trace. Unfortunately it doesn't contain the actual error message, just the three most recent routines on the stack. Besides, the lines seem to be truncated. So, not enough information to say anything.

I am a bit confused though. I thought you had successfully installed Rock 7 and just failed to install the Rolls. Anaconda is only used when installing a system from scratch. Perhaps you should just tell us what exactly you were doing and what happened. What error was displayed before you hit the debug button.

I don't know how Rocks installs itself, but normally a RHEL or Centos install uses a graphical console, and you can access various text consoles with debug information or a shell prompt by pressing Alt-F1, Alt-F2 etc. Perhaps you find more information there.

"I am a bit confused though. I thought you had successfully installed Rock 7 and just failed to install the Rolls",

Am not

but without rocks am able to install centos, But its okay, can you tell me how can I Install and configure rocks cluster?

http://central-7-0-x86-64.rocksclust...rontend-7.html

Can you check the above link, I installed as per the link, there is one mistake.( check the picture below this "5. Select your rolls. Click on the ROCKS ROLLS selection" ) The link they have mentioned in the Network Roll is not working, so I used this link to download the rolls "http://central-7-0-x86-64.rocksclusters.org/install/rolls" we can add the required rolls such as base, core, kernel, centos and the centos updates these are the basic rolls that we have to configure

I have all the required rolls, I tried different way, If you have a vm or oracle virtual box can you try to install and get back to me.

Now I understand better what you are doing. Sorry for being so clueless about Rock.

I am not sure which ISOs to download. Seems complicated, and I don't want to invest the time.

At what point during the installation process do you run into an error, and what precisely is that error?

Today I done again the installation and this time a different error occurred please see the details


The following error occurred while installing. This is a fatal error and installation will be aborted

These are the errors from the console.

Found a solution and its working, thank you for your support.

What is the solution please ?
I have same problem : I am programmer, I install frontend rocks 7-0-x86-64 for a scientist team in the laboratory.
It fails ! I don't know why. The system is black screen, not X11. startx commmand not found. I can authenticate in root and ssh too
But packages are not installed.
rocks command not found.

I think it is driver problem about raid. I don't know. I have installed only idrac update

If i do the same steps on a old machine and virtual machine, I don't have problem

how can i do ?

I am also getting the same error

umount: /mnt/cdrom: mountpoint not found

how did you solve this problem?

installing rocks 7, you must create an http / ftp file (rolls) share server. there is automated script at github.

https://github.com/rocksclusters/roll-server

trust me, fiddling with rocks is exhausting but fun...

Hola, ¿alguien ha podido solucionar recientemente el error 'NoneType' object has no attribute 'updates' que aparece cuándo estás instalando el frontend de Rocks 7 una vez descargados todos los rolls? Gracias
