<div dir="ltr"><div><div>Hi,<br><br></div>My DRBD resync performance is far below system capabilities, and unfortunately available configuration options do not work for me.<br></div><div>I tried to turn off planner in a resource file:<br>
* c-plan-ahead 0;<br>and from the command line:<br>* drbdsetup disk-options <minor> --c-plan-ahead 0<br><br></div><div>I also tried to improve resync rate in a resource file:<br></div><div>* c-plan-ahead 200;<br></div>
<div>* c-min-rate 0;<br></div><div>* c-max-rate 40M;<br></div><div>* resync-rate 40M;<br></div><div>and from the command line:<br></div><div>* drbdsetup disk-options 3 --c-plan-ahead 200 --c-min-rate 0 --resync-rate 40M --c-max-rate 40M<br>
<br></div><div>I also tried various combinations of the above, but all I achieved, was to increase resynchronization to about 4MB/s, which, according to the manual, is a default value for 'c-min-rate'.<br><br></div>
<div>I found a discussion about the same problem, but no solution:<br><a href="http://www.gossamer-threads.com/lists/drbd/users/24230#24250">http://www.gossamer-threads.com/lists/drbd/users/24230#24250</a><br><br>* drbdsetup <minor> show<br>
shows correct settings (what was requested)<br></div><div>* drbdadm -d adjust <resource><br></div><div>shows correctly changed settings with regard to the configured<br><br></div><div><br></div><div>So, is there a way for DRBD 8.4 to improve it, or is there something wrong with the way I try to configure it.<br>
<br>Thanks in advance,<br><br></div><div>-- <br><div dir="ltr"><div>Best Regards,<br><br>Radoslaw Garbacz<br></div>XtremeData Incorporation<br></div>
