Do you know/have any system which works on ZFS such as RDMS? If yes, what is your setup? FreeBSD, ZFS on Linux etc.

Yes, ZFS can support production workloads, such as hosting virtualization systems, running an Oracle database or general NAS or block-level storage presentation.

What are you interested in doing?

Edit:

This depends on your implementation, but ZFS on Solaris, NexentaStor, OpenIndiana, FreeBSD and even on Linux, have been extremely stable and solid for me so far.

  • I'm planning to run a PostgreSQL instance on the top of ZFS, and I thought that any production environment can give me clues about performance and stability.

  • I have years of experience with ZFS on Solaris-like platforms. I've only been testing ZFS on Linux (CentOS 6) for the past 4 weeks. It's been okay so far. No crashes, but a couple of small bugs... Do you have a particular reason for wanting to use ZFS?

  • Yes, my reasons are related with compression. 1- I want to keep more data. 2- I want to see that if benefit of reading less data is bigger than decompressing data on the fly.

  • @metdos Yes, that's exactly why I use ZFS (on Linux) on production DB systems. Using the default compression scheme, there's a tremendous benefit with no negative impact. Using gzip, there's a bigger CPU hit.
