<br>
I have been reading the docs and still seem to be unclear as to
some things-<br>
<br>
Assume I have a two node setup with DRBD in Primary/Primary with
Xen writing to /dev/drbd0 on node1. I use Primary/Primary for
live migration and in my Xen DomU configuration file I use phy:
and not drbd: handler.<br>
<br>
Now, what happens if the disk on node1 begins to fail and the
blocks where /dev/drbd0 resides are corrupted while we continue
to write to this- will these bad/corrupted blocks be replicated
to node2? <br>
<br>
Example aside, in short, I am wondering if a failing disk on a
node will result in DRBD replicating bad block data to the
secondary node. I know there a place in the docs describing
integrity checker using the kernels crypt algo's (like md5) so
maybe thats an option to prevent it?<br>
<br>
In either case, is there any way to prevent bad block data from
node 1 being replicated to node 2?<br>
<br>
