Description

In addition to the primary DAOS_Base_Path, a Domino server can use additional DAOS paths (e.g. for tier storage). DAOS_PreferredPath defines the directory in which new NLO files are preferentially written – existing NLOs are not moved as a result. This allows new DAOS traffic to be directed specifically to a faster SSD or a newer volume, while old NLOs remain on the original, slower storage.
Combined with DAOSMGR_RESYNC_* and tier migration, this is the foundation for a systematic DAOS storage strategy.

Example configuration

DAOS_Base_Path=D:\DAOS
DAOS_PreferredPath=E:\DAOS_NEW

Notes & pitfalls

  • The path must exist and be writable before activation.
  • Existing NLOs are not moved automatically.
  • For a clean migration: tier migration / tell daosmgr resync with rewriting.
  • Extend backup coverage to all DAOS paths.
  • Takes effect after a server restart.
  • Complementary to DAOS_Base_Path, DAOS_Enabled, DAOSMGR_RESYNC_DAY, DAOSMGR_RESYNC_TIME_START.
