Subject: [Disksim-users] How to compile DiskSim 4.0 on 64bit OS

Hi!

There is a thread from December, 2011, where I asked how to compile on 64
bit. Peter Macko answered with a link to a blog which contains the
instructions on how to do it (you have to modify some sources, but applying
the patch is quite simple).

Just look for that thread and for Peter's answer, and you should be able to
compile no problem =)

Subject: [Disksim-users] disksim raid5 problems
Message-ID: <CAL+t72G5C=c8TozZaYUmcLK-va0PmSwzXTweOPHMjAukK0Krhg@mail.gmail.com>

Hi, all. I use disksim to simulate RAID5 disk arrays. My parv file is as
follows:
//---------------------------------------
...logorg...
   Addressing mode = Parts,
   Distribution scheme = Striped,
   Redundancy scheme = Parity_rotated,
...
//---------------------------------------

But when logorg_initialize() run, it change to  "maptype = ASIS;
logorgs[i]->reduntype = PARITY_TABLE;" instead of "maptype = STRIPED;
logorgs[i]->reduntype = PARITY_ROTATED;".

Do any one know the reason?

    when timescale change from 1 to 0.1, the interval between two
contiguous requests become larger (10 times? not sure)

   so, execution time will become longer ~

Subject: [Disksim-users] syssim error--------./src/syssim: internal error:
	last event not completed.
Message-ID: <CAAb6sL2H=gJrOFDowcb7qvCHEy59o1owVtzCQ2kyW0ZqvPcbpw@mail.gmail.com>

Hi guys,

When I was testing the system simulator(Disksim) using a big trace file, it
runs a long time. However, it shows up the error "./src/syssim: internal
error: last event not completed." after 30 minutes (depending on the trace
file). Does anybody get into the same trouble before?

If you encountered the same error like mine, could you tell me the possible
reasons in details about it one by one? That would be very helpful for me.

It is not easy to find out the issue. I think the Disksim is not perfect
and it has some hidden problems itself. So just write down your experience
for me.

I am so appreciated for your help!!! Thanks.

The below function located in the file syssim_driver.c

int main(int argc, char *argv[])
{
...........

    if (!completed) {
      fprintf(stderr,
          "%s: internal error. Last event not completed %d\n",
          argv[0], i);
      exit(1);
    }
...............
}


Leon
