Hello, I have a drbd resource performing replication for a block device on a pair of machines (not clustered), and it works wonderfully. Each evening, we run a cron job that does: drbdadm verify resourceName Every once in a while, "verify" finds a few out-of-sync blocks, and we manually invoke a re-synchronization when this happens. All good. My question is: what are the sorts of things that might be causing blocks to become out-of-sync on this resource? As far as we know, no changes are made or fiddling done on the nodes at any time. Again, verification and re-synchronization works fine -- I'm just trying to get a feel for why these operations are required occasionally. Thank you, Jeffrey
