filesystem_store_datadir=PATH
Optional. Default: /var/lib/glance/images/
Can only be specified in configuration files.
`This option is specific to the filesystem storage backend.`
Sets the path where the filesystem storage backend write disk
images. Note that the filesystem storage backend will attempt to
create this directory if it does not exist. Ensure that the user
that glance-api runs under has write
permissions to this directory.
