    Ultimately the cluster goals would take care of this by allowing
    processes to migrate off a physical machine, then rebooting the
    physical machine, then migrating them back.


Thanks Matt :-)

Will that be implemented in an year or so?
So in the cluster mode I guess two or more systems will be running
with the same IP address?
Some thing like Carp on OpenBSD?
And would it be able to preserve sessions on somethin like an apache server?

Thanks

Re: PF on dragonflybsd

2009-08-15 Thread Matthew Dillon 
   The biggest difference, apart from our PF being fairly old, is that
   keep state is not the default.  But we have a directive to set the
   default (I think OpenBSD doesn't).

   So in a DragonFly pf.conf you would say (near the top):

   set keep-policy keep state (pickups)

   And then keep state would be the default.  pickups is a DragonFly
   directive which I don't know if OpenBSD picked up or not (heh).
   It fixes the problem of rebooting the router box running PF causing
   all TCP connections going through the router to drop.  Without it
   keep state on the TCP connections will throw existing connections
   away because it doesn't see the SYNs or know the TCP window size.

   DragonFly's PF also has a fair-share scheduler (which I wrote).

Ha. I have no idea.  I'm not going to try to guess how long it
will take.

Updated to latest master and have a problem

2009-08-15 Thread elekktretterr 
Hi all,

Ive updated my machine to the latest master to try devfs. Ive run
buildworld,installworld,buildkernel,installkernel and make upgrade and
then restarted and I get the mountroot prompt saying this:

hammer_mount: volume /dev/ad4s1b has an invalid header
Root mount failed: 79

mountroot

What did i do wrong and what can I do to fix this? Was I supposed to rm
/dev before running make upgrade or something like that?

My bad, I was using ad4s1a for root, then found its actually ad4s1d. Ive
booted now and im trying to get kdm/Xorg to start. Any ideas? It gives me
IO Error in XOpenDisplay.

Re: Updated to latest master and have a problem

2009-08-15 Thread elekktretterr 
Futher updates. I have found this is a problem with the nvidia-driver
wrapper.

Simon: Is this something you have to update in the wrapper or can I do it
on my own? Xorg is complaining that /dev/nvidiactl is missing and it
failed to load the nvidia driver.

Question about sound: is it now possible to be playing multiple sounds at
one time without having to give each application a different /dev/dsp*
device?

Thanks,
Petr
