ProcessControl::ExitError: command failed #40
Comments

dmsetup is failing to load the table. The likely reason is you haven't built one of the targets used by that table. There are a few tests that use some debug targets that are only present in my thin-dev tree. But this is occuring so often I think you may be missing the dm-cache target itself. Check the log files in ~/.dmtest/log/ |
|
How should I create the dm-cache target? How should I create the debug targets? |
|
Double check the logs first please. On Mon, 23 Mar 2015 at 03:20 Simon Xu [email protected] wrote:

There are so many failures. Please first have a look at FakeDiscardTests_granularity_equals_max_discard.log: D, [2015-03-23T22:29:11.590051 #5351] DEBUG -- : executing: 'blockdev --getsz /dev/sdc' I checked, there is no test-dev-834780 under /dev/mapper. Any idea of the failure? What dm kernel modules needs to be loaded when running the test suite? Here's the dm modules loaded in my system: $ lsmod | grep dm_ |
|
The FakeDiscard tests use this target from my thin-dev tree: https://github.com/jthornber/linux-2.6/blob/thin-dev/drivers/md/dm-fake-discard.c Perhaps we should rewind a bit. What are you trying to achieve? On Mon, 23 Mar 2015 at 14:36 Simon Xu [email protected] wrote:

My primary goal is to verify that the dm-cache and dm-era modules of my kernel work well. A secondary goal is to use device-mapper-test-suite as a test tool for the device mapper functionality of my kernel. |
|
What are you planning to use dm-era for? (I'm just interested since i On Mon, 23 Mar 2015 at 14:46 Simon Xu [email protected] wrote:

I don't have any plan for using dm-era, I just need to sanity test the newly-added kernel module of the kernel of a Linux distribution. |
When I run tests, I get a lot of "ProcessControl::ExitError: command failed", e.g.

When the test runs, I can't find any /dev/mapper/test-dev* in the system. Is the system missing any packages that are required by the test suite?
