Volume replication: constant load on drives
Hi all,
I have been playing around with the volume replication feature and impacts the performance significantly.
Now, I have swapped out a fairly old server and swapped in a quite new one, to make sure that have hte fasted speeds possible to and from my RAID systems. Both Open-E boxes achieve 110 MB/sec to and from the RAIDs.
Then I started the replciation job and after the initial replication had been finished, both RAIDs still show quite a huge amount of "traffic". The source volume shows consistent reads of 40 MB/sec. constantly, even when no iSCSI initiator is connected to that volume.
The destination volume in turn shows a consistent transfer of 25 MB/sec all the time.
Is volume replicaiton really meant to work this way? I though that the Open-E box would only transfer the blocks that have been changed.
Cheers,
