Fixed In Version: ceph-17.2.6-225
Doc Type: Bug Fix
Doc Text:
.MGR module no longer takes up one CPU core every minute and CPU usage is normal Previously, expensive calls from the placement group auto-scaler module to get OSDMap from the Monitor resulted in the MGR module taking up one CPU core every minute. Due to this, the CPU usage was high in the MGR daemon. With this fix, the number of OSD map calls made from the placement group auto-scaler module is reduced. The CPU usage is now normal.
