Digi,

Thanks for advance again, but I've already tried this. I'm still pegged
at 2MB/s. I've exhausted IRC any google searches involving DRBD slow
sync. I'm really contemplating rebuilding the machine with a RAID 10 to
enhance performance but I still do not know if this is going to resolve
the issue, any thoughts about this? Thanks in advance.

Best Regards,

Dan Lavu

Read this:

http://www.drbd.org/users-guide-emb/s-configure-syncer-rate.html

In short, you should be able to issue a command similar to this:

drbdsetup /dev/drbdo syncer -r 40M

When done, issue this to revert to the drbd.conf settings;

drbdadm adjust r0
