Description

There is a race condition in the database mechanism for enlarging and shrinking storage volumes. This affects both internally triggered resize operations as well as externally triggered resize operations. As a result, the database restarts without being able to perform the resize operation.

Workaround

Avoid externally triggered resize operations.
It will decrease the probability to hit the problem, but won’t avoid it as as it could be triggered internally, without a user request.

Fix

There are no longer crashes due to this race condition.
