Thank you.
I'm not finding any mention of turning this feature on or off, is the default? If so, we're at 9.8P1 and should be running it.

OK, after reading the below it sounds like elastic sizing should already be on and should have prevented my full constituent volume. Why didn't it?
What's proactive resizing? Where can I find out more about it?

I’d actually recommend 9.8 and proactive resizing instead. Elastic sizing is reactive and incurs a latency penalty when used. And it can’t be used with vol autosize. Proactive resizing starts resizing when we get to 60% used and maintains a relatively even free space buffer and can be used with autosize. *From:* Toasters <toasters-bounces@teaparty.net> <mailto:toasters-bounces@teaparty.net> *On Behalf Of *Douglas Siggins *Sent:* Wednesday, May 26, 2021 12:15 PM *To:* Rue, Randy <randyrue@gmail.com> <mailto:randyrue@gmail.com> *Cc:* Toasters <toasters@teaparty.net> <mailto:toasters@teaparty.net> *Subject:* Re: WAFL error on a flexgroup? *NetApp Security WARNING*: This is an external email.

But a look at the eight CVs in the FG shows they range from 22% to 68% full. Is something keeping them more or less balanced? If so, how did it fail? And if not, what the hell?
