We just upgraded to OnTAP 9.1P8. Production system is AFF so compaction is working by default. DR system is FAS8060. I enabled compaction at the aggregate level, but when I tried to enable at the volume level, it was only enabled on the root volumes. Is that because the other volumes are data protection volumes? Is there any value in turning on compaction on this system under these circumstances?
Let's say if I have a volume with no dedup and compression enabled on sas aggr. Then I do volume move to aff node, would this volume be deped and compressed while moved over to ssd? as by default, it will have dedup and compression enable,
I just did a test, the interesting is that if a volume without compression enabled on the source SAS aggr, then if I volume move to a SSD aggr which by default inline compression is enabled, when the move is completed, the compression is still not enabled.
Is your SSD aggregate on an AFF system? If not, I'm not sure if turns on inline by default. Even if it's moved to AFF, I don't recall if it turns it on automatically with a vol move. The default definitely applies when creating new volumes on AFF.
Yes, SSD aggr I am referring to here is on AFF. Understood inline dedup/compression/compact will be turned on by default for new volumes.
But, I just don't understand why volumes with no compresson on SAS from source node when moved to SSD@AFF, his compression would not be turned on as I already tried. I would like to know what the logic explanation is.
