Crash Dumps in Ubuntu with EC2

[mario-aleman]

Hi everyone.


I'm trying to configure an Ubuntu AMI capable of record crash dumps.
ubuntu-precise-12.04-amd64-server-20131003 (ami-3f32ac3e)


I followed this recipe:
https://wiki.ubuntu.com/Kernel/CrashdumpRecipe


But after having all configured and testing it, it doesn't show any dump files in /var/crash


I also found this happened to another user [bug unrelated] https://bugs.launchpad.net/ubuntu/+s...c2/+bug/614853


And in the thread says that the person was trying to capture also the crash, but the files
never appeared.

In first instance I thought it was because I didn't had a swap partition, but added it and there were no changes.


Is this a bug? or is just a misconfiguration?

By the way here are the commands to check that crashdump is running:

root@ip-172-31-11-34:/var# cat /sys/kernel/kexec_crash_loaded
1
ubuntu@ip-172-31-11-34:~$ cat /proc/cmdline
root=LABEL=cloudimg-rootfs ro console=hvc0 crashkernel=384M-2G:64M,2G-:128M

Greetings!
