Upgraded from 6.12.13 to 7.2.7 in the last few days. The update path went pretty well so far due to good documentation of (breaking) changes. Now I stumbled across this entry in the 7.3.1 changelog: Could someone please tell me which configurations are affected? I could not find any hint in this thread or bug reports. Actually, I would like to wait with the update to 7.3.x until version 7.4.x is out. But if there is a serious issue with drive replacement I'd better not wait.
