Hi there,
We are in the middle of a data migration from FAS2650 to AFF220.
AFF220 nodes have been added to the FAS2650 cluster, so we are able to perform the data migration using volume moves.
I do notice new volumes created on the AFF filer have the following storage efficiency settings:
Schedule: -
Policy: auto
Compression: true
Inline Compression: true
Inline Dedupe: true
Data Compaction: true
Cross Volume Inline Deduplication: true
Cross Volume Background Deduplication: true
Volumes that I move from FAS -> AFF have the following settings:
Schedule: sun-sat@0
Policy: default
Compression: false
Inline Compression: false
Inline Dedupe: true
Data Compaction: true
Cross Volume Inline Deduplication: true
Cross Volume Background Deduplication: true
This means the volumes I moved from the FAS system do not have have compression enabled. What would be the best way forward here? Is it OK to enable compression on those volumes?
I think the way to go is the following but I would appreciate some guidedance or at least someone telling me this is OK to do..
1. Migrate volume FAS -> AFF using vol move
2. Change volume efficiency policy to "auto"
3. Enable compression on volume
4. Run a full volume scan using the following command: "volume efficiency start -vserver vs1 -volume VolA -scan-old-data true -all-data"
Thanks in advance!
Tony
