I want to setup a NFS server on GCP, so used a VM, mounted the GCS bucket on /vol using the gcsfuse. Then installed nfs-kernel-server packages on the VM, created a dir nfs_share under /vol, added the entry in /etc/exports and while restarting the nfs-kernel-server service, ran into the below error:

Filestore a service of GCP (NFS instance) needs to be deployed with 1TB storage as a minimum, thus looking for alternatives. Above approach looks feasible, but unable to get the nfs service up and running.
I am trying to stop Clamav service in Linux, but I am not able to do that.
I have installed Clamav in a seperate directory.
When running below command:
$ systemctl stop clamav-daemon
I get this error message:
Warning: Stopping clamav-daemon.service, but it can still be activated by:
clamav-daemon.socket
When running:
$ systemctl status clamav-daemon
I get:

When you are logged in as a normal user which can be understood by seeing the $ sign in your command, clamav won't stop. You need to perform the following command.
It will stop clamav for only logged-in session
$ sudo systemctl stop clamav-daemon
To see the status
$ sudo systemctl status clamav-daemon
It will return:

If you have created symbolic link of clamav daemon to start the program automatically when pc boot then you need to remove that link so that clamav shouldn't start automatically
$ sudo systemctl disable clamav-daemon
I am trying to install redis on my AWS server. I have Ubuntu 18.04 installed on it. I am following steps to install redis from digitalocean article.
When i run sudo systemctl status redis command i am getting below error.
screenshot
I tried to edit /etc/systemd/system/redis.service file and added Type=forking under [Service] section but still getting the same error.
Can anyone suggest me how i can get it fixed?
Thanks in advance.
Based on same digitalocean tutorial, actually it's running fine.
Run this command sudo systemctl restart redis.service, we get (showing "failed" on last line):

After searching for hours, it seems like it's some difference between systemctl & service and nothing more, but the actual redis server is running fine. Corrects me if that's not the case. Here's the link: https://askubuntu.com/questions/903354/difference-between-systemctl-and-service-commands
You can even check if redis is working fine, by redis-cli ping, should print PONG
I also encountered this problem, then I tried to check it again.
Finally, I found that when I authorized /var/lib/redis, I entered the wrong command, causing the redis account to have no access to /var/lib/redis.
sudo chown redis:redis /var/lib/redis
sudo systemctl restart redis
succeeded.
I´m using docker tools on windows.
create command was working perfectly last week and I managed to create a number of machines on Digital Ocean. Then I tried today with no success. I repeated the same command with different regions and I always get the same result:

Update
It´s working with ubuntu 14:
--digitalocean-image=ubuntu-14-04-x64 so it seams like a problem with the default image (ubuntu-16-04-x64)
This seems to be hitting a lot of people. TL;DR: There is a bug in docker-machine v0.12.0 and this issue can be resolved by upgrading.
Logging in to the DigitalOcean instance and running journalctl -xe provides more information:
-- Unit docker.service has begun starting up.

-- Subject: Unit docker.service has failed
-- Defined-By: systemd
-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel
The key here is docker daemon is not supported on Linux. A bug in docker-machine's version comparison code caused an incorrect systemd unit file to be produced (located at /etc/systemd/system/docker.service.d/10-machine.conf) on certain versions of Ubuntu.
A fix has been committed and a new release (v0.12.1) was made.
You can grab the latest release at: https://github.com/docker/machine/releases/tag/v0.12.1
When I start a EC2 Instance with
docker-machine create --driver amazonec2 --amazonec2-region eu-central-1 --amazonec2-instance-type t2.2xlarge aws-test
docker-machine can create the VM, exchange the certs but the start of the engine fails.
Log in the EC2:

Yesterday it worked with the same configuration. Could there be a change in the used AIM since yesterday? I tried it from a different host but get also the same error.
It seems that there is a bug in the Docker Version that was rollout yesterday. A Workaround for us:
docker-machine create --driver amazonec2 --engine-install-url=https://web.archive.org/web/20170623081500/https://get.docker.com
