qtree quotas on deduplicat
2012-02-22 12:40 PM
I'm trying to figure out what affect enabling deduplication on volume will have on qtrees with quotas.
Say I have a 1 TB VOL with multiple qtrees and quotas. QtreeX - quota 300 GB; 270 GB utilized - has a ton of duplicate data.
After enabling and completing a dedupe pass, VOL utilization is reduced by 20%. 50 GB of the space savings was in QtreeX.
Will the quota utilization report now report 220 GB utilized or will it still report 270 GB used.
I found the following in the deduplication FAQ pdf. I'm assuming from this that the quota report will still indicate qtree utilization as 270 GB and will not be impacted by the reduced VOL utilization but I'm not entirely sure that that is what this is telling me:
26. ONCE A VOLUME IS DEDUPLICATED, HOW ARE QUOTAS REPORTED?

Quotas do count space saved by compression. In a volume that has compressed
data, quotas count the sum of allocated used space and spaced saved by
