An argument for isolating root volume is that we are still warned in the netapp admin classes that if the root volume gets full, the filer will crash. We can build qtress to limit client to just under 100% or we can reserve 1% snap and turn off snaps. But will either of those really work? Will the filer potentially crash on a full volume even if it is not root volume?

I don't disagree but this seems to be a paradigm of the past. With the R100 out, and OT 6.2 comming soon, the limitations are quickly disappearing. Currently I plan to just snapmirror volumes to the R100, but with 6.2 I plan to create volumes in the 1TB+ range and snapmirror the qtrees (everything we do is in qtrees). I used to be a volume nazi for probably the same reasons you mention (no volume was to *ever* get above 400GB's non-snapshot), now I don't see that as a problem anymore. I have no issues with volumes going past 1TB if this works as advertised, and I have no reason to think it won't.
So, do you still think vol0 should be seperate? And don't give me the "That's the way we've always done it..." routine :-] Keep in mind the R100 does mostly archival, backup/restore, and misc funtions like db exports and IT tool storage, not traditional production stuff.

Jeff, I personally don't like active data on vol0. In the past I have put archive data on vol0 because it is low impact. I happen to be a little more paranoid than some but that is just me and we have been bitten before by putting highly volatile on the root volume. Chris

Now that the R100 has come out I was wondering what people think of the seperate vol0 concept? In the old days it wasn't quite so bad; ok, so you wasted a 4gb drive or maybe even an 18gb drive. But now we're looking at tossing a 136gb drive for what? Squat really.
So what's the new thought on this? Do you not waste the disk on a seperate vol0 and just keep tight reigns on qtrees? Or is there still an argument for vol0 on it's own?
Thanks.
