A vol-move operation will cause compaction to happen. I know it's not ideal but at least its internal. Obviously a scanner is preferred but functional

Strange how compaction appears to work with vol move but not with snap mirror. . On Sep 23, 2016, at 4:39 AM, Steiner, Jeffrey <Jeffrey.Steiner@neta

My understanding is that both are block based operations so it makes sense to me that the blocks would be put down on disk unchanged. Perhaps it has
View ArticleRE: AFF and 4:1 guaranteed efficiency
I would guess that snapmirror is currently looking at the physical blocks on disk, whereas a vol-move is a step up the chain and it can look at block

I vaguely remember running a test on an ONTAP 9 simulator. What I found was that if the destination aggr had compaction enabled, then snapmirror into

I just want to point out a few things based on my experience and feedback from other people. Pure Storage - block only. You do not get any bells
View ArticleRE: AFF and 4:1 guaranteed efficiency
Okay, I heard back. Engineering says that snapmirror and vol-move should BOTH trigger compaction. If you didn't see savings, perhaps something about t

For the snap mirror to trigger compaction, the aggregate must have compaction enabled. Otherwise, it is just a SnapMirror transfer Get Outlook for iO

Compaction setting is done at the volume, and not the aggregate level. Francis Kim Cell: 415-606-2525 Direct: 510-644-1599 x334 fkim@berkcom.com<mail

Have to disagree. I pulled up an ONTAP Â 9 simulator and did this exact test. My source was a non compacted volume. Destination was non compacted. Res
View ArticleRe: AFF and 4:1 guaranteed efficiency
One more thing When you have a mirrored destination, you can't set compaction on that volume which makes sense since you can't modify the destination
View ArticleRe: AFF and 4:1 guaranteed efficiency
There are options on aggregate and volume levels. Compaction is enabled by default on aggregate and volume level for AFF. But in FAS you should enabl
View ArticleRe: AFF and 4:1 guaranteed efficiency
Right. And ONTAP will not allow you to drop a destination mirror based on XDP or LS into an aggregate with compaction enabled. Not 100% sure about TDP
