Allowing overruns (=> wrong data, unpredictable side effects, crash) is IMHO a bug. According to usual classification systems, a bug causing data damage or crash has severity critical. > (2) applies only to i386, this is not an issue on an 64 bit architecture > If LINBIT's customers demand a fix for this problem, we will fix it > for i386 -> I.e. if you want to have that limit removed, ask LINBIT! That's a limit of hardware/architecture. Personally I would move to 64 bit hardware, if I would have the need for such large amounts of data. > (3) Will be on drbd-8's roadmap. ACK. I assume low priority now, but in 2 years there can be a stronger need. Helmut Wollmersdorfer
