So I'm looking at files on my ZFS volume that are compressed, and I'm wondering to myself, "self, are the values shown here the size on disk, or are they the pre-compressed values". Google gives me no great results on the first few pages, so I headed here.
This really relates to my VMware environment. I had some "things" happen on my platform that required me to Storage Vmotion everything off of a particular zpool. When I did that, I saw most VM's inflate to nearly their thick provisioned size. What didn't swell to that size went to about 2/3 provisioned (non-Nexenta storage). I have been seeing 1.3-1.5x compression ratios on pretty much everything I turn compression on for (these are general use VM's - webservers,SQL,firewall,etc). My question is this - when I'm looking in the file structure, or in the datastore browser in VMware, am I seeing the uncompressed file size, or the compressed filesize? My gut tells me that since they inflated _so_ badly when I storage vmotioned them, that they are the compressed values, but I would love to know for sure. -Matt Breitbach _______________________________________________ zfs-discuss mailing list email@example.com http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
