Unable to configure Firmware Assisted dump

[bugproxy]

[SRU justification]
This represent a hardware enablement SRU : Firmware assisted dumps (fadump) are not possible on LTS.

[Impact]
The fadump mechanism cannot be used on Power systems running Trusty

[Fix]
Backport fadump functionality from makedumpfile 1.5.8 present in Wily and onward.

[Test Case]
See comment #9 : The proposed SRU has been tested from a PPA on a Power VM.

[Regression]
None expected from a functionality point of view as it is a new feature. Existing code paths are minimally modified.

[Original description of the problem]

---Steps to Reproduce---
1) Using latest daily ISO install 14.04.02 as a Power VM guest.
2) Upgrade the kernel to 3.19 level (3.19.0-18-generic)
3) In order to use Firmware Assisted Dump feature update the kernel command with fadump=on.
4) Reboot.

Post reboot using kdump-config load command fails with following message :

# kdump-config load
Memory for crashkernel is not reserved
Please reserve memory by passing"crashkernel=X@Y" parameter to kernel
Then try to loading kdump kernel
 * failed to load kdump kernel

# kdump-config status
current state : Not ready to kdump
#

# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinux-3.19.0-18-generic root=UUID=3ea23bcf-7269-432f-bacc-f82c6cdd774e ro splash quiet fadump=on crashkernel=2G-4G:320M,4G-32G:512M,32G-64G:1024M,64G-128G:2048M,128G-:4096M vt.handoff=7
# cat /sys/kernel/fadump_enabled
1
# cat /sys/kernel/fadump_registered
0
#

# dmesg | grep -i Firmware
[ 0.000000] Reserved 5120MB of memory at 97279MB for firmware-assisted dump

#
# cat /boot/config-3.19.0-18-generic | grep -i FA_DUMP
CONFIG_FA_DUMP=y
#

Are there any user space fixes missing which prevents me from configuring firmware assisted dump ?

== Comment: #4 - Hari Krishna Bathini <email address hidden> - 2015-06-12 05:28:24 ==
This patch makes kdump-tools fadump aware so as to switch between
kdump & fadump seemlessly based on the dump method enabled (fadump/kdump).

Thanks
Hari

Hi Canonical,

Can you please assign this bug to an appropriate developer to fix it as soon as possible.

This has been hanging around a long time without an update.

Thanks for your support.!!

Hello,

Would it be possible to have someone test the potential modification from a PPA ? Since it concerns addition of a new feature to a stable release, I would prefer to have a bit more testing done before uploading

Kind regards,

..Louis

Hi Louis,

I have asked internally if someone can test it. If you already have a PPA repository for the packages, can you offer the repository entry to add to sources.list to pull from please? Thanks.

[Louis Bouchard (louis)]

Hello,

One way to make the PPA available is to use add-apt-repository (part of software-properties-common package) with the following syntax :

$ sudo add-apt-repository ppa:louis-bouchard/test-makedumpfile

then run sudo apt-get update

Otherwise you can use the following :

$ sudo -s
$ cat << EOF > /etc/apt/sources.list.d/louis-bouchard-test-makedumpfile-trusty.list
deb http://ppa.launchpad.net/louis-bouchard/test-makedumpfile/ubuntu trusty main
# deb-src http://ppa.launchpad.net/louis-bouchard/test-makedumpfile/ubuntu trusty main
EOF

then
$ apt-get update

Kind regards,

...Louis

Hello,

Please be aware that the PPA is not a definitive fix and will eventually disapear. Now that I know that it works, I will proceed to get this fix included in the official archive. I will update this bug when it happens.

Kind regards,

...Louis

debdiff for trusty SRU

[Chris J Arges (arges)]

Hello bugproxy, or anyone else affected,

Accepted makedumpfile into trusty-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/makedumpfile/1.5.5-2ubuntu1.5 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Louis Bouchard (louis)]

Hello Praveen,

Would it be possible for you to test the uploaded packages in the trusty-proposed archive to confirm that the fix is adequate. Please don't forget to remove the test packages provided in the PPA.

Kind regards,

...Louis

[Breno Leitão (breno-leitao)]

Tested iternally at IBM by Praveen, and he reported:

"Tested with https://launchpad.net/ubuntu/+source/makedumpfile/1.5.5-2ubuntu1.5 package and it works fine ,yes before trying with new package i removed PPA build"

[Louis Bouchard (louis)]

Thank you for the test.

It should be released publicly in a few days.
