Hi Everyone. I am having a quota issue on qtrees that are in flexvols. I've been noticing one particular qtree growing over the past several weeks. It grows until it hits the quota, users scream, I increase the quota and so on... It got to the point where I just didn't believe that much space was being consumed. I started doing du commands all over the place, but could not find where that qtree was growing. A du at the root of that qtree did not show it growing either.
Here's some output from quota reports for a particular qtree:
Yesterday morning: tree 45 group ideas 535695812 576716800 432819 Yesterday at 5pm: tree 45 group ideas 550047436 576716800 432915
A du of that qtree actually went down between those times.
So I did a quota off/on and let it re-initialize.
This morning: tree 45 group ideas 414589436 576716800 432904
I know that area did not fall by over 100GB overnight.
And a few hours later: tree 45 group ideas 418067772 576716800 433545
The quota report usage shows it has grown by several GB. The du of the qtree is about flat.
I thought maybe the snapshot space is being counted against the quotas. I didn't think that was the way it was supposed to work. I maintain 8 hourly, 5 nightly, and 3 weekly snapshots of this flexvol. So yesterday I deleted the weekly.2 early, waited a while, and then ran the quota report. It went up.
I don't know where to go from here. I opened a case with NetApp. They were going to look at it in the lab.
Does anyone have any suggestions ?
FAS3040. OnTap 7.2.6.1
Last month after all the talk about this release and quotas and panics, I opened a case with NetApp. They had me change setflag wafl_enable_allocation_size from a 1 to a 0.
Thanks, Paul
