Hi Wade,<br>
<br>
There seems to be some issue in syncing the existing data in the
volume using Xsync crawl.<br>
( To give some background: When geo-rep is started it goes to
filesystem crawl(Xsync) and sync all the data to slave, and then the
session switches to CHANGELOG mode).<br>
<br>
We are looking in to this.<br>
<br>
Any specific reason to go for Stripe volume? This seems to be not
extensively tested with geo-rep.<br>
<br>
Thanks,<br>
Saravana<br>
