Subject [jira] [Comment Edited] (IGNITE-6711) DataRegionMetrics#totalAllocatedPages is not valid after node restart

--------------------------------------------------------------------

Metric calculation is now fixed. There are some unfamiliar extra allocations at very first
restart with PDS enabled, but in general the metric looks consistent.

[~avinogradov], could you please review the fix?

> Currently, data region metric tracks total allocated pages by a callback on page allocation.
However, when a node with enabled persistence is started, some of the pages are already allocated,
which leads to an incorrect metric value.
