@stevewest15 Thx for SMlog. I don't see anything suspicious

In the log of the source host I see Oct 14 20:09:06 XCP25 xapi: [error||3 ||storage_migrate] Tapdisk mirroring has failed
Can you also provide /var/log/SMlog that corresponds to the migration time. As it was yesterday maybe you should look in /var/log/SMlog.1
Thx
