> A power outage interrupted Garage mid-write on the LMDB metadata database. LMDB uses mmap’d I/O and, by default, operates with MDB_NOMETASYNC and MDB_NOSYNC (Garage sets metadata_fsync = false by default) No, Garage disables LMDB's safety mechanisms by default. By default, LMDB performs whatever necessary syncs and is 100% crash proof, even in the face of power outages. Garage's problems are of their own making, not because LMDB has unsafe defaults. |
