I just tried to connect up a remote node after performing Truck Based Replication of a 525G volume. I changed the IPs in /etc/drbd.conf and ran "drbdadm --stacked adjust all" on the primary. The resource connected immediately, both nodes moved to WFBitMap[ST] and stayed there, the load shot way up on the primary, and the mounted partition became unwritable. While I could read it locally on the primary, boxes that had the volume mounted over NFS were unable to read or write. When I noticed this, I ran "drbdadm --stacked disconnect all" and, after a minute or so, the resource disconnected and everything became usable again. The link between the sites is capped at 1 megabit and I had forgotten to change the syncer rate down from the initial Gb speeds. Could trying to sync at 900 megabit over a 1 megabit connection have caused the problem? If so, now that I've reduced the sync rate to 100K (or 800 kilobit), will I still get stuck with a disk that's unusable for quite some time after re-connecting the remote resource? If it matters, the connection between the two sites is via an OpenVPN tunnel. Thanks! -Ben
