Hi Chris,
Try deleting mysql_201708090830/ snapshot on the destination. And
resend but this time do a full send of that snapshot, don't use -p. I
wonder if a full send, rather than incremental makes a difference.
Follow it up with the rsync command to compare origin and destination.

Hi Chris,

Hi Chris,
The kernel version that I test is "4.4.0-89-generic" as I tested on ubuntu lxd
If I
want to change the kernel version I have to upgrade the host box.
As you suggest the rsync to compare the subvolumes. I found the point.
the subvolumes are different only after I start to del old subvol
I'll test and response the result to you soon.
I have another question about the combination within Host lxd ubuntu and lxd
