I am running my root pool on a 60 GB SLC SSD (OCZ Agility EX). At present, my rpool/ROOT has no compression, and no deduplication. I was wondering about whether it would be a good idea, from a performance and data integrity standpoint, to use one, the other, or both, on the root pool. My current problem is that I'm starting to run out of space on the SSD, and based on a send|receive I did to a backup server, I should be able to compress by about a factor of 1.5x. If I enable both on the rpool filesystem, then clone the boot environment, that should enable it on the new BE (which would be a child of rpool/ROOT), right?
Also, I don't have the numbers to prove this, but it seems to me that the actual size of rpool/ROOT has grown substantially since I did a clean install of build 129a (I'm now at build133). WIthout compression, either, that was around 24 GB, but things seem to have accumulated by an extra 11 GB or so. Or am I imagining things? Is there a way to get rid of all of the legacy stuff that's in there? I already deleted the old snapshots and boot environments that were taking up much space.
