File systems

  • XFS is required if you want to use disk space quotas for Elasticsearch data directories.
  • On RHEL and CentOS, XFS file systems must be created with the -n ftype=1 option to make sure they can work with the OverlayFS storage driver used by Docker.
  • If SELinux is enabled: Your SELinux configuration must allow mounting Docker sockets into containers (required for deployment management to work)
