"/proc/partitions not found" error is showing up

Question

I am configuring a webserver in Ubuntu 10.04. More particularly I am installing DataStax OpsCenter.

Unfortunately, the logs are spammed with this error:

ERROR [pool-3-thread-7] 2013-02-15 22:04:34,533 Long os-stats collector failed: Process failed: cat /proc/partitions
  Exit val: 1
  Output:
cat: /proc/partitions: No such file or directory
ERROR [pool-5-thread-3] 2013-02-15 22:04:56,846 Error getting devices and partitions #<IOException java.io.IOException: Process failed: cat /proc/partitions
  Exit val: 1
  Output:
cat: /proc/partitions: No such file or directory>

Why do I get cat: /proc/partitions: No such file or directory?

I really doubt that the problem is with the application I am using, because if I run this command from command line cat /proc/partitions I still get No such file or directory and from what I have found in some forums that directory should be created when the OS is starting up, I could be wrong but that's as far I got.

Answer 1

As you said in your comment, you're on a virtual private server (VPS). OpenVZ as well as other VPS solutions don't offer access to /proc/partitions. The whole /proc partition is a virtual filesystem (procfs). The structure is maintained in the kernel. So it will not work to manually create the file.

The DataStax OpsCenter has a support forum. At the moment I found no questions qhich deal with your problem. However the experts there should be able to help you out.

Answer 2

To get proc file system you might need to mount it.

mount proc /proc

To get list of partitions I use following commands. Each of them gives list of partitions.

fdisk -l 
parted -l
df -h
mount

Note: mount only displays list of volumes currently mounted and df shows statistics of mounted volumes.

Try making the folder yourself. This is how you do it: in a terminal, type

sudo mkdir /proc
sudo mkdir /proc/partitions

See if your logs still appear.

Extract all to a single folder ... keep all the contents under a single folder. check if proc.exe and oci.dll are in same folder **otherwise it will error out.

run the proc program from command prompt

1. start -> run -> cmd
2. cd c:\singlefolder (contents where all the extracted contents are present)
3. type proc - it should give out some output (if you get its installed correctly)
4. to run - type proc progamname.pc
5. check the same folder it should have generated a programname.c file in same directory
6. you can run the .c file using vc++ or any c++ compiler (borland or others)

Sample program :

#include <stdio.h>
#include <conio.h>

int main(int argc, char *argv[])
{
  printf("Hello, world!\n");
    getch();
  return 0;
}
