As a second test I did the same with version: 8.3.8 (api:88/proto:86-94) GIT-hash: d78846e52224fd00562f7c225bcc25b2d422321d build by root at drbd01.localdomain, 2011-02-15 22:51:22 0: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r---- ns:32913 nr:0 dw:145 dr:2621481 al:2 bm:6 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:0 Hosted on two VirtualBox Centos5 Servers. Writing with dd if=/dev/urandom of=/mnt/t.dat bs=512 count=1 oflag=direct seek=$RANDOM conv=notrunc & some test records in a ext2 filesystem on top of /dev/drbd0. This blocks when the LV backing device on secondary is suspended. Same behavor: ko-count is ignored! BTW: my dd examples in previous posts did use skip= but should also seek= So this is the explanation for the Concurrent write warnings, because i've always written to the beginning of the device.
