I ment something like this - link(table file, tmp2 file); fsync(tmp2 file); unlink(table file); link(tmp file, table file); fsync(table file); unlink(tmp file). We can do additional logging (with log flush) of these steps if required, postpone on-recovery redo of operations till last relink log record/ end of log/transaction abort etc etc etc. Vadim
