Duplication, what do the numbers mean??

[Jasper]

I'm currently duplicating my pool. The total size of the data is 10.2TB. Drivepool numbers are as follows -

 

Duplicated = 13.4

 

Unduplicated = 3.62

 

Other = 8.15

 

Progress = 22.9%

 

Does Drivepool use some sort of Chinese math?

Duplicated is the total amount of space used by duplicated files.

When this is done, this will be double the amount of data you ahve.

If you're duplciating everything, it will be 20.4TBs of duplicated data.

 

From the looks of it, and assuming a few things, your pool should this:

Duplicated = 13.4TB

Unduplicated = 3.62TB

Other = 8.15GB

 

This means that you have 6.7TBs of data duplicated, (x2 since you have two copies) and 3.62TBs of unduplicated data.

That's 10.32TBs of data, which is pretty spot on from what you've said.

 

As for the other data, if it's in GBs, then that's fine (and fairly decent for that size pool)

 

As for the progress, that's it's current progress on the current duplication pass (if you rebooted, or restarted the service, or changed settings, it will reset the progress, so it may not be completely indicative of the overall progress since starting). 

 

If you need any clarification or have any more questions, don't hesitate to ask.

Thanks. No problem, just curious.

You're very welcome.

And if you're not familiar with it, it can be a bit confusion.  

 

Either way, it sounds like it's happily duplicating data.
