<DIV>
<DIV>Hello,</DIV>
<DIV> </DIV>
<DIV>I use DRBD for a while now.</DIV>
<DIV>But today after "image creation crash of 850GB" a the disks where out of sync</DIV>
<DIV> </DIV>
<DIV>So i synced the secondary again with the primary</DIV>
<DIV> </DIV>
<DIV>secondary</DIV>
<DIV>drbdadm secondary main</DIV>
<DIV>drbdadm disconnect main</DIV>
<DIV>drbdadm -- --discard-my-data connect main</DIV>
<DIV> </DIV>
<DIV>primary</DIV>
<DIV>drbdadm connect main</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>at this time the sync speed was very slow.</DIV>
<DIV>my normal speed is between 29000 and 32000 on a normal cat5e/gigabit network</DIV>
<DIV>i have also rebooted the servers.</DIV>
