• Plugin version (or commit ref) : v1.0.7-3
• Docker version : Docker version 17.06.2-ee-8, build 4e8ed51
• Plugin type : legacy/managed
• Operating system: Linux testhost 3.10.0-862.el7.x86_64 Add support for encryption key #1 SMP Wed Mar 21 18:14:51 EDT 2018 x86_64 x86_64 x86_64 GNU/Linux

Created a docker volume using docker gluster plugin. After volume creation, the volume could not be deleted. Disabling, removing and reinstalling the plugin ultimately removed the volume. Commands I ran to demonstrate the problem follow:

$ docker volume ls
DRIVER VOLUME NAME
$ docker volume create --driver sapk/plugin-gluster --opt voluri=10.10.10.3:testvol,10.10.10.4:testvol,10.10.10.5:testvol --name testvol
testvol
$ docker volume ls
DRIVER VOLUME NAME
sapk/plugin-gluster:latest testvol
$ docker volume rm testvol
testvol
$ docker volume ls
DRIVER VOLUME NAME
sapk/plugin-gluster:latest testvol
$ docker volume prune --force
Total reclaimed space: 0B
$ docker volume ls
DRIVER VOLUME NAME
sapk/plugin-gluster:latest testvol
$ docker plugin disable sapk/plugin-gluster
sapk/plugin-gluster
$ docker volume ls
DRIVER VOLUME NAME
$ docker plugin enable sapk/plugin-gluster
sapk/plugin-gluster
$ docker volume ls
DRIVER VOLUME NAME
sapk/plugin-gluster:latest testvol
$ docker plugin disable sapk/plugin-gluster
sapk/plugin-gluster
$ docker plugin rm sapk/plugin-gluster
sapk/plugin-gluster
$ docker volume ls
DRIVER VOLUME NAME
$ docker plugin install sapk/plugin-gluster
Plugin "sapk/plugin-gluster" is requesting the following privileges:

• network: [host]
• device: [/dev/fuse]
• capabilities: [CAP_SYS_ADMIN]
  Do you grant the above permissions? [y/N] y
