I personally was a heavy qtree user back in the 7-mode times and when I set up my first cDOT gear I was looking desperately to replicate what I got on 7-mode to the new platform and quickly figured out that it doesn’t make sense here anymore, at least for most of the cases I’ve been using it for.

So I’d agree with „yes on 7-mode, no on cDOT“.

Just my 2 cents,

Betreff: Re: Everything in a qtree?

One of the main advantages of a qtree is the ability to use move style commands, but there's a default qtree for each volume that allows that to happen without anything explicit. The only time I use qtrees is if I need to create multiple shares inside a single volume, which is a standard we've gotten away from for backup reasons.

I’d second that…and obviously if you want any sort of user level quotas, or want to be able to mirror/move the data in the qtree.

For my customers....I called that: TMAC's rule #1 ;)

Always use qtrees. Always.

In 7-mode, it really did not hurt and when migrations came up, it was trivial to move the qtree piece,

In the first versions of cDOT though, qtrees were really not used.

Migrating was done (via the netapp tools) at the volume level (since cDOT had no use for qtrees)

Personally, I would stick with the qtrees if you plan on sticking with 7-mode.

Snapmirror/vault can be done at a volume, qtree or "all top directories but qtrees" layer.

Hi,

Back about 7 years ago when we purchased our first NetApp systems we hired a NetApp consultant to help us set them up.  One of the things he told me was to always put everything in a qtree.  Whether it’s a cifs shares, nfs export, or luns . . . put them in a qtree.  I have followed that practice.  I think part of this was that our NetApp systems are for a particular application and we use snapvault for some of the backups (luns and cifs shares).  This is all on OnTap v8 in 7-mode. 

As I’m about to create some CIFS shares for other uses, I’m wondering if this is a good practice.  The new shares would be volume snapmirror’ed to a DR site, but no snapvault. 

Any opinions are appreciated.

Thanks

Rick
