<p class=MsoNormal>Well ive been playing with the product for a few weeks and
it works great on the LAN. I tried setting virtual boundaries and
lowering the speed to 100k and setting Protocol to A and I was wondering how
far can one device ‘fall behind’ before it may lose the ability to
sync. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>For example, Im maintaining a 2TB device but have my drbd on
the WAN link which is 3Meg pipe (2 bonded T1s) obviously the data will never be
able to keep up with the writes during the day but at night when the business
slows to a crawl I should be able to ‘catch up’ as long as the
system doesn’t lose track of where it is. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I was trying to look at the conf and a few other things
seeing if there was a way to manage that (including how to tell if the buffer
is near being full etc) or at least see it. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thx<o:p></o:p></p>
