Hi Matt,
1000M means 1000 Mb/s NOT 1000mbps. To reach 1000M you should have at
least one (probably two) 10gbit interface(s). Since you have two 1gbit
interfaces (bonded with balance-rr?) a value between 100M and around
170M would be more appropiate.

I was playing with the settings yesterday and it let me set it at 600M and
it didn't make a difference in the sync speed at all. I then tried it with
your suggestion, dropped it to 150M just to be safe. Still no difference.
I wonder what the deal is. Could it be that this is the initial sync?

I'll leave that decision to Lars and Phil, but another option is to
simply include that patch in the Debian drbd-utils package.
And then have different agents on different distros? My vote would go

You are still mixing megabits and megabytes. Your 1000 megabit pipe won't
take a 600 megabyte stream, or a 150 megabyte stream. The maximum is about
125 MBps.
DRBD talks (and is documented to talk) bytes. Most everyone else talks bits.
You don't mention the speed you are getting.
Also,
Well we're the perfect supplements for each other because, as you can see, I
don't know DRBD from a hole in the wall.
Yes, it's a brand new resource. I don't think I would say it's full of
zeros, as it has a clean ext3 file system on it.
Yes, I would LOVE to skip the sync, I've been dealing with

Well, to be certain, I'd dd the disks to zeros individually, and then start
with them sync'd.
drbdadm down all
dd if=/dev/zero of=/drbdbacki
I would suggest looking at the disk hardware. What sort of RAID card
are you using in the servers? If you are using an HP Smart Array there
is some tuning to do to get some descent performance out of those as
they have a rather deep buffer.

OK, You can skip the zero, but the devices won't pass an online verify. It
won't hurt anything. All the sectors that need to be synced will be synced.
The disks are mostly zeros, so an online verify wouldn't do much, but it's
nice to know.
To find out how long the DD will take, "kill -USR1 task
Actually, that makes some sense. If the network is way faster than the sync,
and the dd (which doesn't even use the network) is the same speed, then
there is something bad wrong with the underlying device or configuration.
You are not going to be happy until you get that fixed. Then, the dd sho
It's a 3ware RAID card.
My drbd.conf:

protocol C;
handlers { pri-on-incon-degr "halt -f"; }
disk { on-io-error
I'm in the middle of a "verify the upgrade procedure" for drbd 8.3.10 to
8.4.0.
Just for chucks, I did the dd command here, to see the performance I get.
root@Drbd0:/usr/src/drbd-8.4.0# cat /proc/drbd
version: 8.4.0 (api:1/proto:86-100)

I think a number was intended, but I don't know what that number might be.

minor-count may be a number from 1 to FIXME.
