DRBD set sync speed

by 1 Comment

The default sync rate is normally defined in your drbd configuration (mostly /etc/drbd.conf)

1
2
3

syncer {
    rate 100M; 
}

If you are setting up a virtual machine on drbd cluster you need to produce more I/O and your physical machines are under heavy load. You can stop some services or you can reduce the sync rate.

Set temporary sync rate:
You need to issue this command only on one of your nodes!

1

root@drbd-node1:~# drbdsetup /dev/drbd0 syncer -r 10M

Enjoy the easy solution;)
