Hi Lava Team I am trying to mount a directory of worker (host computer) to LXC instance running on it with job. I have added this entry in lxc default configuration file of worker computer. Default Configuration file path is : /etc/lxc/default.conf Entry is :- lxc.mount.entry = /var/lib/nfsdir var/nfsmnt none bind,create=dir 0 0
After restart lxc service. I executed lava job then this directory "/var/lib/nfsdir" of worker machine is not mounting on LXC instance in directory "/var/nfsmnt".
But if i manually create and start lxc instance on worker, then this directory "/var/lib/nfsdir" of worker machine is mounted on LXC instance.
Can anyone assist me on this issue, that how i can resolve this issue.

You are missing a forward slash before 'var/nfsmnt' above.

How did you restart lxc service?
"/var/lib/nfsdir" of worker machine is not mounting on LXC instance in directory "/var/nfsmnt".
A fresh LXC created and started during the job execution will not have the directory /var/nfsmnt hence it will not work.
You may try 'mkdir /var/nfsmnt; mount /var/nfsmnt' before accessing the directory.
But if i manually create and start lxc instance on worker, then this directory "/var/lib/nfsdir" of worker machine is mounted on LXC instance.
What are the things you did after starting lxc? Did you create '/var/nfsmnt' directory?
Thank You.
Thanks Senthil But still its not working with Lava job. Can we debug LXC-instance with more logs.

You are missing a forward slash before 'var/nfsmnt' above. [chetan] No Senthil, we need not to provide forward slash, as its defined in this version of lxc.

[chetan] /etc/init.d/lxc-net restart, /etc/init.d/lxc restart
"/var/lib/nfsdir" of worker machine is not mounting on LXC instance in directory "/var/nfsmnt".
[chetan] directory is created automatically on LXC instance with name
/var/nfsmnt but content of worker machine directory is not synced/mounted in this directory.
A fresh LXC created and started during the job execution will not have the directory /var/nfsmnt hence it will not work.
You may try 'mkdir /var/nfsmnt; mount /var/nfsmnt' before accessing the directory.
[chetan] this step is not required. I have followed these steps simply with additional parameters. https://wiki.debian.org/LXC#bind_mounts_inside_the_container
But if i manually create and start lxc instance on worker, then this
directory "/var/lib/nfsdir" of worker machine is mounted on LXC instance.
What are the things you did after starting lxc? Did you create '/var/nfsmnt' directory? [chetan] I just did config change and created a new lxc instance with name lxc-ubuntu and then start instance. By attaching to instance, i am able to access /var/nfsmnt path on LXC.
Thank You.

Hi Chetan,

I tried this on my local setup and it just works from within a LAVA test job.
See the complete test job log here - http://paste.debian.net/978242/ The job definition is here - http://paste.debian.net/978243/
You can see 'ls -alh /var/iso' called in the test definition lists the contents of the directory which is mounted from the entry as defined below:
$ cat /etc/lxc/default.conf lxc.network.type = veth lxc.network.flags = up lxc.network.link = virbr0
