I see the above log lines using journalctl

Issue got solved. The make/install was executing this step "install -m 755 docker-lvm-plugin /usr/libexec/docker" . However didnt have a docker directory in "/usr/libexec/" path, so the file got copied under the name docker. Moved the file into a folder docker instead and issue is resolved.

@SantoshRaoBlr I tried this on the upstream/master branch, however I am not able to reproduce this issue. I deleted my existing docker directory under /usr/libexec and when I did a sudo make install it creates the docker directory under /usr/libexec and deploys the docker-lvm-plugin binary successfully.

[root@localhost docker-lvm-plugin]# cd /usr/libexec/
[root@localhost libexec]# ls docker -lt
ls: cannot access 'docker': No such file or directory

[smahajan@localhost docker-lvm-plugin]$ sudo make install
install -D -m 644 etc/docker/docker-lvm-plugin /etc/docker/docker-lvm-plugin
install -D -m 644 systemd/docker-lvm-plugin.service /usr/lib/systemd/system/docker-lvm-plugin.service

I am able to start the docker-lvm-plugin and run the docker volume commands. I see in the comment you mentioned install -m 755 docker-lvm-plugin /usr/libexec/docker however in the Makefile we are using install -D -m 755 $(BINARY) $(BINDIR)/$(BINARY) with -D .

Are you building docker-lvm-plugin from latest master ?

[shishir-a412ed]

@SantoshRaoBlr I see what's going on 😀 In your first comment. https://github.com/projectatomic/docker-lvm-plugin/issues/48#issue-316228889

You are doing a git clone of https://github.com/shishir-a412ed/docker-lvm-plugin Please see under README.md of that project:

This project has been moved under projectatomic/docker-lvm-plugin (https://github.com/projectatomic/docker-lvm-plugin)

You need to clone https://github.com/projectatomic/docker-lvm-plugin

Thank you very much for the quick response, and helping me sort it out. Will take care of the same.
