Comment 2 for bug 1955670

Hi Goutham,

As per my understanding, volumes that are part of a group should not be allowed to be transferred as there is no optimal way to make that happen. The volumes should first be removed from the group and then transferred.
Going through the code, i can see we've a check regarding consistency group[1] but nothing regarding generic volume groups which we should have. I will try to look into adding a check for it. Thanks for reporting this.
