First, let’s get a little information

Could you give us the output of the following commands.

(I am assuming your problem aggregate is aggr0)

aggr status –v aggr0

df –hA aggr0

snap list –A aggr0

aggr show_space aggr0

Next, can we narrow down the growth to a single volume or group of volumes?

How about providing a df –h for each volume and also a snap list <volume> for any volumes using excessive snapshot space.

Hi all,

In the last 36 hours or so we have a 19Tb aggregate that is growing above 18Tb used.

Usually the aggregate used level only grows if we grow its volumes.

This is different - I was forced to delete snapshots and shrink volumes to get it back under 90%.

And in the last 3 hours its back above 91% - used level is climbing 5-10g/minute

I so far can not see where the growth is coming from,

Aggr snapshot is OFF

thanks for any tips!
