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, if you have 3 resources syncing, each will try for the syncer limit.
So, to use 50% of your capacity to sync 3 resources, you'd specify the rate
as 21M. Note: you can change the rate on the fly, during a sync.

Subject: Re: [DRBD-user] DRBD won't take 1G syncer rate

 

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?
