Not enough space for drivers in AWS g4dn.4xlarge instance

Asked 2021-May-26 at 10:38

Premise: I'm a bit of a newbie in using Amazon AWS or Linux partitioning in general.

So, I need to train a Tensorflow 2.0 Deep Learning model on a g4dn.4xlarge instance (the one with a signle Nvidia T4 GPU). The setup went smoothly and the machine was correctly initialized. As I see in the configuration of my machine I have:

8GB root folder;
200GB of storage (that I was able to mount on startup using this guide https://devopscube.com/mount-ebs-volume-ec2-instance/#:~:text=Step%201%3A%20Head%20over%20to,text%20box%20as%20shown%20below)

Expand the existing EC2 root EBS volume size from 8 GB to 200 GB from the AWS EBS console. Then you can detach and delete the EBS volume mounted on /newvolume

Terminate this instance and launch a new EC2. While launching the instance, increase the size of root volume from 8 GB to 200 GB.

I fixed that in two steps: first I did make change the kube-proxy config to it's default. Then i did write to HOST's /sys/module/nf_conntrack/parameters/hashsize the hash size which needed by kube-proxy manually. Then delete kube-proxy pods and let it's deployment to create theme again automatically. The main problem is Flannel configuration. flannel deployment doesn't looks for my cluster default ip range and set it's ip range 10.244.0.0/16 So i did edit it's configuration and change that to my range:

It is clear that your EC2 instance has disk usage issue (disk gets full). You successfully increased the volume size (as shown in lsblk output) but you also need to extend the file system, as described here.

Essentially, you should run sudo growpart /dev/xvda 1 and sudo resize2fs /dev/xvda1. Use df -h again to verify.

In order to optimize performance, you should consider:

Using a dedicated volume for your workload (i.e. mount a new, larger EBS volume on /mnt/data and configure your application to use this path for data storage)
Resize this volume and/or change type (i.e. use provisioned IOPS SSD)

Scrapy also supports S3 for storage.

You can configure scrapy logging to use a specific log file (--logfile FILE which you can later delete) or disabled it altogether (--nolog, not recommended).

QUESTION

How to enable gpu passthrough on centos/rhel/ol8 using snapd's lxd/lxc containers?

Asked 2021-Mar-19 at 13:09

The guides I have for deploying LXC on CentOS is to install snapd's lxd https://www.cyberciti.biz/faq/set-up-use-lxd-on-centos-rhel-8-x/

SnapD is a type of service that allows installing debian/ubuntu based packages with the logic being lxd is most up to date on that platform.

Well. I'm all open to installing an alternative version if it's easier to enable gpu passthrough.

Ultimately I'm trying to build a container environment where I can run the latest version of python and jupyter that has gpu support.

I have some guides on how to enable gpu passthrough.

Docker (compose): connection refused without sudo

Asked 2021-Feb-19 at 16:58

All was fine until "something". After that "something", I could use docker and docker-compose with sudo but without it the docker would hang indefinitely and the docker-compose would return connection stack traces.

Doesn't work:

Running docker without sudo hangs indefinitely. Temporarily fixed by exporting DOCKER_HOST=tcp://127.0.0.1:2375.
docker-compose without sudo returns with connection refused. It's not about connecting to specific container but for all basic commands such as docker-compose ps.

The problem was a dead context entry.

Solution

Removed the dead context named remote using docker context rm remote.

Even though docker context ls was pointing default as default, it was necessary to do docker context use default for the context to be properly updated.

As a partial fix I had previously set DOCKER_HOST to tcp://127.0.0.1:2375. After updating context the env variable had to be unset, i.e. unset DOCKER_HOST.

Lazy commands, assuming context remote:

That guide adds manually the necessary OpenGL shared libraries in the LXD container, and by doing so, does not add the Vulkan shared libraries.

LXD now supports the NVidia container runtime (provided by NVidia), therefore you can use it instead. Follow the more recent guide at https://blog.simos.info/running-x11-software-in-lxd-containers/

LXD DHCP handing out IP addresses

Asked 2021-Feb-10 at 18:05

I have been using LXC/LXD (4.0.4) for a while now and love the flexibility they provide - I however have started having some odd problems on my network. It seems the LXD is running a DHCP server and handing out address to other devices on my network.

I am running as a bridged network between the containers and the host computer and have assigned static address on the host machines as well as in the containers.

when i do a grep on DHCP on the host machine i see an LXD DHCP running and the address range that is being handed out to the other machines - as opposed to coming from the DHCP server i set up to address addressing.

Is there an easy way to disable the DHCP server, preferable through netplan or is there another method.

This problem is severely impacting my development as my test devices are getting the wrong IP assignments

Thank you in advance.

When you use LXD and you have configured a private bridge (that lxdbr0 network), then LXD has configured for you a dnsmasq instance that listens on the lxdbr0 network interface and responds to DHCP requests. That is, LXD responds only to the lxdbr0 network interface or what you get when you run the following command. All three network interfaces have their own dnsmasq because they are MANAGED by LXD.

Nothing wrong per se. The boot partitions are usually separate for security and recoverability reasons (plus they sometimes need to be a "simple" filesystem type like FAT).

You can increase the size of the logical volume to the full 10T using LVM tools:
