I am running this on 3.13 kernel (ubuntu 14.04), DRBD 8.4.3 I am observing this on *one* pair of servers, the other servers seems to be fine. However, I did found hardware-related issues on these servers, related to CPU stuck messages during online verification. This was cured by BIOS update (that bumped CPU microcode from 0x14 to 0x15), this is a Xeon E5620 CPU. However, now, as I resync (online verification marked lots of OOS), I get the very same messages: On Secondary: block drbd1: BAD! sector=1771175320s enr=54051 rs_left=-51 rs_failed=0 count=128 cstate=SyncTarget On Primary: block drbd1: BAD! sector=1771175320s enr=54051 rs_left=-51 rs_failed=0 count=128 cstate=SyncSource I have lots of these as the sync continues, from 3 to 10 per minute. Before doing the online verification, I had *silent* data corruption on the secondary (I tried to move services to secondary, in order to work on primary with OS updates), this is when I noticed secondary was in fact out of sync: missing files, wrong disk space, ... clear signs of filesystem corruption, even though /proc/drbd showed UpToDate/UpToDate. I blame the initial corruption on the hardware problems, due to firmware, as I have not observed this on any other pair of servers. Thanks!
