We've actually been running it in production at Netflix for a few microservices for over a year (as Scott said, for a few workloads, but a long way from everywhere). I don't think we've made any kind of announcement, but "ZFS" has shown up in a number of Netflix presentations and slide decks: eg, for Titus (container management). ZFS has worked well on Linux for us. I keep meaning to blog about it, but there's been so many things to share (BPF has kept me more busy). Glad Scott found the time to share the root ZFS stuff.
- voncopec 10y agoIf I had to choose between a filesystem with silent and/or visible data corruption up to pretty much eating itself and having to restore an entire server, versus a filesystem for which you can trust but could have a kernel deadlock/panic..I would choose the latter, and in-fact did. I have seen a few servers with ext4/mdraid over the last five years have serious corruption but have had to reset a ZoL server maybe twice.

After I removed the last spinning disk, one of the SSDs started returning garbage. 1/3 reads are returning garbage and ext4 freaks out, of course. It's too late and the array is shot. I restore from backup. This would have been a non-event with ZFS. I've got a few production ZoL arrays running and the only problems I've had have been around memory consumption and responsiveness under load. Data integrity has been perfect.
- voncopec 10y agoI've seen the same type of thing with respect to memory and load.
