CONTAP-213769: CIFS/SMB read/write Performance degradation might be observed when using FlexGroups
Issue
FlexGroup CIFS/SMB read/write performance may be degraded after performing FlexGroup rebalancing in ONTAP releases before the "Fixed In Versions".Additionally, intensive write workloads on the rebalanced files might also trigger CPU watchdog and/or aggregate relocation hangs that are tracked in CONTAP-317207 and CONTAP-319470.
