Hello,I'm re-posting this message as it is not showing up after 5 days since the initial post.
I'm (try to) running drbd-8.4.3 on a 3.4.54-8.el6.centos.alt.x86_64 kernel (CentOS6-4 with xen support). I set up my nodes with a resource tier0 resource tier0 { protocol C; startup { degr-wfc-timeout 120; } net { sndbuf-size 0; } disk { on-io-error detach; resync-rate 25M; } syncer { rate 25M; al-extents 3833; verify-alg sha1; } meta-disk internal; on ctb5 { disk /dev/sda3; device /dev/drbd1; address 172.23.10.1:7799; } on ctb6 { disk /dev/sda3; device /dev/drbd1; address 172.23.10.2:7799; }Here is the sequence of commands and status after I zeroed out the partition### Load module, device creation and "drbdadm up $resource" went ok, leading to the Connected state below[root at ctb5 ~]# modprobe drbd[root at ctb5 ~]# drbdadm create-md tier0Writing meta data...initializing activity logNOT initializing bitmapNew drbd meta data block successfully created.success[root at ctb5 ~]# cat /proc/drbdversion: 8.4.3 (api:1/proto:86-101)GIT-hash: 89a294209144b68adb3ee85a73221f964d3ee515 build by root at ctb5, 2013-08-18 15:58:37 1: cs:Connected ro:Secondary/Secondary ds:Inconsistent/Inconsistent C r----- ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:221273604########A this point, I declared ctb5 as the primary node:[root at ctb5 ~]# drbdadm primary --force tier0[root at ctb5 ~]# cat /proc/drbdversion: 8.4.3 (api:1/proto:86-101)GIT-hash: 89a294209144b68adb3ee85a73221f964d3ee515 build by root at ctb5, 2013-08-18 15:58:37 1: cs:SyncSource ro:Primary/Secondary ds:UpToDate/Inconsistent C r---n- ns:84 nr:0 dw:0 dr:3736 al:0 bm:0 lo:0 pe:1 ua:3 ap:0 ep:1 wo:f oos:221273604 [>....................] sync'ed: 0.1% (216084/216084)M finish: 307:19:28 speed: 0 (0) K/secThe other node (ctb6) is now aware that this node (ctb5) is primary:[root at ctb6 drbd-8.4.3]# cat /proc/drbdversion: 8.4.3 (api:1/proto:86-101)GIT-hash: 89a294209144b68adb3ee85a73221f964d3ee515 build by root at ctb6, 2013-08-17 13:13:16 1: cs:SyncTarget ro:Secondary/Primary ds:Inconsistent/UpToDate C r----- ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:0 pe:3 ua:0 ap:0 ep:1 wo:f oos:221273604 [>....................] sync'ed: 0.1% (216084/216084)M finish: 3073:14:40 speed: 0 (0) want: 0 K/secbut nothing is ever written to disk on the secondary node (speed is 0).

Drbd never complained about anything, so why doesn't it start syncing?Hope someone can help me, thanks.Massimiliano
