SQLITE_E_IOERR_READ

SQLITE_E_IOERR_READ corresponds to SQLITE_IOERR_READ: SQLite received a VFS read failure while reading a file. SQLite documents possible causes including storage faults or a filesystem that became unavailable while the file remained open.

What to check

  • Check operating-system storage and mount events at the first failure timestamp.
  • Verify access to the main database and its journal/WAL companion files from the same service account.
  • After storage is stable, run integrity checks against a safe copy before attempting repair or restore.
