Hi ThompsG
Thanks for the prompt response. Did you mean df -h instead of vdf -h?
The esxi host can see the datastore has 66% free with df -h.
On that host, I have 4 vms, and two of them have seen a same issue with the datastore.
I did a rescan before reading your post, I've re-scanned storage on the host again to see if it makes any difference. Will keep you posted.
Regards
