IIRC the HOWTO used to indicate 9000 instead of my 6k, but for all my hardware 6k seemed to work out near optimal, and I can now see average syncs of ~22000KB/s (which is probably maxing out my pathetic raid boxes). some advice for it seems to be over on the wiki faq now: http://wiki.linux-ha.org/DRBD_2fFAQ#head-3d7a189ec67920e48d69e294610914e66571de14 and a mention of it in the old article. http://www.drbd.org/drbd-article.html > ./iperf -c 10.0.0.2 > ------------------------------------------------------------ > Client connecting to 10.0.0.2, TCP port 5001 > TCP window size: 16.0 KByte (default) > ------------------------------------------------------------ > [ 3] local 10.0.0.3 port 32788 connected with 10.0.0.2 port 5001 > [ ID] Interval Transfer Bandwidth > [ 3] 0.0-10.0 sec 1.02 GBytes 872 Mbits/sec > > > It´s obvious that it is a gbit link!!! > > drbdsetup /dev/drbd0 show <SNIP> > rate = 153600 KB/sec > group = 1 > al-extents = 257 > > system: suse sles9, drbd 0.7.14 > > And now, any ideas? > > cheers > Stefan > <SNIP>
