Hello,
I have a couple of servers with SSD based raid arrays (capable of
writing 550+MB/s to the disks). And a 10Gb/s network (HP NC552SFP
network adapter HP E8206 network switches)
Before installing the 10Gb network adapter the syncrate was limited
to
around 102MB/s (1Gb/s?)
After Installing the 10Gb network adapter it was still impossible to
get more than 102MB/s sync rate between the servers.
I would like to have a 300MB/s sync rate. When I set this as a fixed
sync rate in my drbd84 resource file I noticed that this value is
ignored and 102MB/s is used.
How can I increase the syncer rate in drbd84?
Variable-rate synchronization is on by default in DRBD 8.4. I had to
set c-plan-head to 0 before I was able to change sync rate even
temporarily. More information can be found at
http://www.drbd.org/users-guide/s-recent-changes-defaults.html.
Btw, offtopic question just because curiosity, what SSD disks you are
using in raid? :)
