----------------------------------
Summary: Update agent for hierarchical roles
Key: MESOS-7047
URL: https://issues.apache.org/jira/browse/MESOS-7047
Project: Mesos
Issue Type: Bug
Components: agent
Reporter: Neil Conway
Agents use the role name in the file system path for persistent volumes: a
persistent volume is written to
{{work_dir/meta/volumes/roles/<role-name>/<persistence-id>}}. When using
hierarchical roles, {{role-name}} might contain slashes. It seems like there
are three options here:
# When converting the role name into the file system path, escape any slashes
that appear.
# Hash or otherwise encode the role name before using it in the file system
path.
# Create a directory hierarchy that corresponds to the nesting in the role
name. So a volume for role {{a/b/c/d}} would be stored in
{{roles/a/b/c/d/<persistence-id>}}.
If we adopt #3, we'd probably also want to cleanup the filesystem when a volume
is removed.
