GrootFS fails to mount XFS filesystem: `exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/loop0` about garden-runc-release HOT 13 CLOSED

We have created an issue in Pivotal Tracker to manage this:

https://www.pivotaltracker.com/story/show/156001041

The labels on this github issue will be updated when the story is started.

from garden-runc-release.

Hi @JY-Lee, it looks like we weren't able to create the xfs filesystem we use to enforce container quotas. Could you check which stemcell version (and especially what kernel is in the stemcell) you are using? Thanks!

from garden-runc-release.

Hi @julz ,
this was with stemcell version of bosh-vsphere-esxi-ubuntu-trusty-go_agent | ubuntu-trusty | 3468.21 and i am not sure about the kernel as i have deleted diego. Plus, v3445.2 stemcell also had same result.
The thing is,,, i am working with bosh version 261 and have succeded depolyment on 'Openstack' using the same manifest.

Thank you!!!

from garden-runc-release.

Hi @JY-Lee - it looks like the latest vsphere stemcell is 3541.9, could you please try upgrading the stemcell to the latest version and let me know if the problem still occurs? If it does, could you also please bosh ssh in to a VM and run uname -r to check the kernel version. Thanks!

from garden-runc-release.

Hi @JY-Lee , Recently, I also came across same issue. I was using "3.13.0-142-generic" kernel version. But when i upgraded it to 4.4.0-105-generic, it worked for me.

Thanks

from garden-runc-release.

Thank you, @julz and @AmitRoushan .
For v 3468.21 Stemcell >> diego cell kernal version was "4.4.0-111-generic"
and for v 3541.9 Stemcell >> diego cell kernal version was "4.4.0-116-generic"

I did success deployment, but it only happens when i deploy it twice. ( succeeded only in second execution ) Or it takes some time after the occurring error to have $ bosh vms cell state change to "running"

Both of the cases occurs error of following at the first deployment:

## I would like to know if there's any way to make it succeed by my first deployment? (by first chance; deploying one time only )

Thnak you very much!!

from garden-runc-release.

Also, ## does vSphere Starndard env support grootfs? I am curious as i am working on vSphere Starndard env for this. Thanks.

from garden-runc-release.

Hey @JY-Lee we are still looking into your initial mounting failure, and will let you know if you make any progress.
As for garden not succeeding in a first deploy, but then succeeding in a second; we have seen recently that some slow-to-deploy environments are hitting a harsh default timeout, and that garden does not report as running in that time which makes the deployment fail with no visible error. We have bumped this in a newer release. Have you seen any other errors recently?

from garden-runc-release.

Hi @Callisto13 , thank you for your time.

As you suggested, I have updated to 'garden-runc v1.12.1' and tested on few different environments.

However, it came up with an error as addressed below.

I suppose having 'timeout' replaced to 2mins from 30secs in 'garden-runce-release v1.12.'1 have effected the number of error occurring.
If so, ## is there any way (or function) to manipulate 'timeout' in 'deigo installation manifest' file??

FYI, i have tested with 'garden_healthcheck.timeout' by adjusting the time and it also threw same error.

Thank you very much!!

from garden-runc-release.

hey @JY-Lee, i suggested the monit timeout as a potential cause for the second issue you mentioned:

I did success deployment, but it only happens when i deploy it twice. ( succeeded only in second execution )

There is no way to configure the monit timeout from the manifest I am afraid. The increased monit timeout has produced the unintended side-effect of starting the garden ctl script more than once, which is why you are seeing the bad superblock error more frequently now.
The garden_healthcheck.timeout is a different setting and would not have lead to either of your problems.

We are still trying to reproduce the issue. Is this a production environment?

from garden-runc-release.

I have also changed the title of this issue since the original was very generic and not search friendly for others who may have come across the same thing

from garden-runc-release.

Hi, @Callisto13 , This is a testing environment.
Thank you very much for your time and effort.

from garden-runc-release.

@JY-Lee we are still unable to reproduce so could you try to deploy again? and then right after it fails (assuming it fails for the same reason), ssh in and get the following debug information:

1. the contents of /var/log/messages and all of dmesg (not with | tail). These may be quite long, so please attach them as files.
2. the outputs from:
   • uname -a
   • blkid
   • modprobe xfs and lsmod | grep xfs
3. If modprobe exited 0 and lsmod returned at least one line, please also get the outputs from:
   • file -s /var/vcap/data/grootfs/store/unprivileged.backing-store
   • xfs_check /var/vcap/data/grootfs/store/unprivileged.backing_store
   • cat /proc/self/mountinfo

Thanks!
