For all we know, you did this: disk { no-disk-barrier; no-disk-flushes; no-disk-drain; no-md-flushes; } Which is an explicit no-no and would definitely break fsync. But I also give you this from the manual: http://www.drbd.org/users-guide/re-drbdconf.html "Unfortunately device mapper (LVM) might not support barriers." That leaves you with either flushes or drain as the fsync method. Since you don't have a BBWC, you must have at least this option enabled. Then we can talk. -- Shaun Thomas OptionsHouse | 141 W.
