l2arc Problem?

[JR Gonzalez]

Is there a reason my l2arc (128GB SSD) is reporting ~380GB?

Is the disk correctly identified as 120GB in the other management pages and/or the command line?

L2ARC is compressed in 9.3 IIRC so if you have highly compressible data in there the webGUI might be reporting the "uncompressed equivalent" size.

 

[JR Gonzalez]

Yes. It is properly identified as 128GB. I get the compression but going from 128GB to 380GB? Singularity compression algorithm?

3:1 isn't unreasonable depending on what you're storing. You'd be surprised how well a Windows Server install compresses.

IME very well especially once you drop it in the recycle bin.
