Hi, We are trying to use DRBD to sync up to LVM logical volumes on PowerPC 720 VMs. We can get the initial connection messages but as soon as we tell it to sync the primary to secondary it goes to WFConnection. drbdsetup /dev/drbd0 events -u 2 ST 0 { cs:WFConnection ro:Secondary/Unknown ds:Inconsistent/DUnknown r— } 20813 ST 0 { cs:WFReportParams ro:Secondary/Unknown ds:Inconsistent/DUnknown r— } 20814 ST 0 { cs:WFBitMapT ro:Secondary/Primary ds:Inconsistent/UpToDate r— } 20815 ST 0 { cs:WFSyncUUID ro:Secondary/Primary ds:Inconsistent/UpToDate r— } 20816 UH 0 before-resync-target 1 ST 0 { cs:WFSyncUUID ro:Secondary/Primary ds:Inconsistent/UpToDate r— } 20817 ST 0 { cs:SyncTarget ro:Secondary/Primary ds:Inconsistent/UpToDate r— } 20818 ST 0 { cs:NetworkFailure ro:Secondary/Unknown ds:Inconsistent/DUnknown r— } 20819 ST 0 { cs:Unconnected ro:Secondary/Unknown ds:Inconsistent/DUnknown r— } 20820 ST 0 { cs:WFConnection ro:Secondary/Unknown ds:Inconsistent/DUnknown r— } 20821 ST 0 { cs:WFReportParams ro:Secondary/Unknown ds:Inconsistent/DUnknown r— } 20822 ST 0 { cs:WFBitMapT ro:Secondary/Primary ds:Inconsistent/UpToDate r— } 20823 ST 0 { cs:WFSyncUUID ro:Secondary/Primary ds:Inconsistent/UpToDate r— } 20824 UH 0 before-resync-target ## /var/log/messages: Nov 30 19:20:37 info1 kernel: klogd 1.4.1, ---------- state change Nov 30 19:20:37 info1 kernel: blk\_queue\_max\_segment\_size: set to minimum 65536 Nov 30 19:20:37 info1 kernel: block drbd0: Starting worker thread (from cqueue [3618]) Nov 30 19:20:37 info1 kernel: block drbd0: disk( Diskless → Attaching ) Nov 30 19:20:37 info1 kernel: block drbd0: Found 1 transactions (1 active extents) in activity log.

We have drbd 8.3.7 installed on suse11 SP1 I’m suspecting either a configuration issue or a patch. ## – amadera amadera’s Profile: [http://forums.novell.com/member.php?userid=120594](http://forums.novell.com/member.php?userid=120594) View this thread: [http://forums.novell.com/showthread.php?t=448989](http://forums.novell.com/showthread.php?t=448989) ---
