Snapshot filling is the result of data churn. If there's no obvious data writes, then next place I'd look is whether someone's trying to defrag or similar. Doesn't change the data, but does reshuffle the blocks and thus the snapshot. Never seen this before
FAS3250 ONTAP 8.1.2
at 2am the volume hosting 110 VMs fills up and starts alerting
Get the call and delete several snapshots to take it to 83%, reboot the 110 VMs ;(
I have lots of tools (splunk, inmon etc) they are not able to show why this volume filled up
ideas?
