Seems very high for a HA-System. On the other hand maybe someone wants the system to wait for a whole weekend. 3 days = 259200 seconds. I would like an easier to remember plain value like 100000, 200000 or 300000. > I don't get the next sentence: >>>From my experience as tester I will not expect, that _any_ values will >>work correctly without "dry-run". > hm? Very easy explanation: As we all know, usally numbers represented in text are converted to an easier to handle representation inside a program. This can be hex, decimal packed, floating etc. and mostly will be of fixed length. Even bignums will have an upper limit (e.g. 64Kdigits). If there is no check for a maximum value at input, funny things can happen in program logik afterwards: overruns, skip to negative values, truncated values, which possible could cause crazy program behaviour. I do not aspect many of these errors, as the bug rate of drbd is very low (congratulations!) and at minor level. > well, we have had a bugzilla, but we did not use it. > and it would be very fast very heavily out of date. > do you want to keep it up-to-date, > and kick Phillip or me every now and then? Yeah. But it needs a minimum of cooperation from developers. E.g. such messages like "solved, ready for retest", "won't solve", priorities etc. Helmut Wollmersdorfer
