Runs a Dynamic Host Volume plugin with dummy values.
|
|
|
|
Usage:
|
|
$0 <plugin> <operation> [target dir] [uuid]
|
|
|
|
Args:
|
|
plugin: path to plugin executable
|
|
operation: fingerprint, create, or delete
|
|
create and delete must be idempotent.
|
|
any other operation will be passed into the plugin,
|
|
to see how it handles invalid operations.
|
|
target dir: directory to create the volume (defaults to /tmp)
|
|
uuid: volume id to use (usually assigned by Nomad;
|
|
defaults to 74564d17-ce50-0bc1-48e5-6feaa41ede48)
|
|
|
|
Examples:
|
|
$0 ./example-plugin-mkfs fingerprint
|
|
$0 ./example-plugin-mkfs create

|
$0 ./example-plugin-mkfs create /some/other/place
