No, it was on Solaris back when ZFS was new. It seemed like these people enjoyed...

So because a file system had issues 20 years ago when it was new.... Do you still drive a car with a carburetor and drum brakes?

ZFS is now incredibly stable and durable, with the exception of some of the early non production ZFS on Linux work that is now fixed (and was specifically billed as non prod use). It has seen me through issues that other file systems would have failed on, including drive failures, hard shutdowns, a bad RAM module, SAS card being fried by a CPU water cooler, etc. Years and terabytes just on my systems, zero issues.

In fact one of the tests that Sun did back in the day was to write huge amounts of data to a NAS and pull the power cord mid writing. Then repeated that a few thousand times. It never corrupted the file system.

Needs citation. I was in the very earliest crop of ZFS users (ca. 2003), and then went on to build a storage product based on ZFS (ca. 2006) and then a cloud based on ZFS (ca. 2010) and an object storage system based on ZFS (ca. 2012) -- and ran it all up until essentially present day. I have plenty of ZFS scars -- but none of them involve lost data, even from the earliest days...
