When container content is assembled it is possible that reshape
is in progress. To avoid md to run reshape without monitoring.
Before setting array parameters sync_max is set to 0, to not allow md
for any move forward. After array parameters are set, sync_max is set to current
reshape_progress. This is current reshape start point.
Note that md is still blocked, and reshape is not continued.
