Hi Brian,
The issue started with failing mon service and after that both OSDs on that
node failed to start.
Mon service is on SSD disk and WAL/DB of OSDs on that SSD too with lvm.
I have changed SSD disk with new one, and changing SATA port and cable but
the problem is still remaining.
All disk tests are fine and disk doesn't have any error.
