Hi guys, thought I would put this out there in case anyone else has seen this.
A couple of weeks ago we upgraded from vSphere 6.5 to 6.7, the system seemed fine and worked as expect for 2 days. On the evening of the second day the Storage DRS seemed to go crazy and moved around 500 vmdks' . This caused our tiered storage to become full and stopped working correctly.
We only had on "Space balance automation level" which up to then move 3 or 4 a night, unless if we have worked on some machines and then it could be up to 40 but these were rear.
Has anyone else seen this kind of behaviour, was thinking it could be a bad upgrade but then why did it take 2 days to show itself ?
The datastore has approx 35 2tb LUNs
