Hello again,

I am quite sure that you actually don't want Linstor / DRBD to migrate a
volume from a LVM pool into a volume from a LVM_THIN pool. If you would do
that, DRBD would (have to) trigger a full resync, replcating the whole
content of the LVM volume to the LVM_THIN volume, making the usage of the

Yes, the default for new installations changed with 0.7.2 from "MAC" to

In that case you might want to increase the log level on the satellite to

That the controller warns about satellite being offline (and thus storage

If I remember correctly, the controller retries every 10 second or so to
