Error while doing the DRBD setup


  • During DRBD setup after starting DRBD service on primary and secondary server
on Primary "cat /proc/drbd" it shows status Primary:Unknown and in Standalone state
on Secondary status is Secondary:Unknown and in Waiting for Connection (WC) state
  • Running the command
dmesg |grep drbd
gives a log indicating peer disk size mismatch


  • Even when the df -h shows that the partition sizes are same, there may be a mismatch in actual sizes when the harddisk vendors are different


  • Run the following command on the primary
drbdadm resize all
  • Restart the DRBD service on both the servers
