Hello,
as drbd is a RAID1 over Ethernet it alway syncs the whol disk at the first time.
During it's running "normal" RAID1 stuff is going on.

Betreff: [DRBD-user] Fwd: performance of SYNC
dear sirs,
I have started drbd system OK. The speed of SYNC is only 64,344KB/sec for
GIGA NICs. It is good.
But DRBD sync whole partition(523,291,644KB). How can I only sync the
data file(10,571,500KB)?
regards,
Longming 3/23
