Hello,
yesterday i setup two Raid5 boxes with DRBD:
each 2GB RAM, drbd-device (partition) is 140 GB !
connected via x-over cable on 100MBit NICs
drbd version: 0.58 from CVS last Weekend (works very well :)
some lines from messages:
20:12:14 pop2 kernel: drbd: module initialised. Version: 58
20:12:14 pop2 kernel: drbd : vmallocing 4403064 B for bitmap. @fc9aa020
20:12:14 pop2 kernel: drbd0: Connection established.
20:12:14 pop2 kernel: drbd0: size=140898051 KB / blksize=4096 B
20:12:37 pop2 kernel: Checking ReiserFS transaction log (device 2b:00) ...
20:12:37 pop2 kernel: Using r5 hash to sort names
20:12:37 pop2 kernel: ReiserFS version 3.5.29
when i start repl this is really slow, i did some calculation, and i think
my 140 GB will last 3 days for replication (it could last about 4 hours
with my 100MBit )?!
20:13:26 pop2 kernel: drbd0: Synchronisation started blks=7 int=0
after five hours i stopped :
02:23:23 pop2 kernel: drbd0: Synchronisation done. 3444693 blks sent
Is it possible to increase the throughput(blks= ) of drbd ?
>from drbd.conf:
protocol=B
net {
sync-rate=10240
