Stuff we've discussed on IRC.

"That ZFS almost ate a terabyte because it had a snit is only half of why I am really unhappy with ZFS right now. The other half is that ZFS is the perfect example of the new model of Unix systems and system administration, and this new model is busy screwing us."
"The new model is non-transparent and tools-less. In the new model of systems there is no level between 'sysadmin friendly' tools that don't really tell you anything (such as ordinary zpool) and going all of the way down into low-level debuggers (such as zdb) plus reading the fine source code (where available). There is no intermediate level in the new model, no way to get ZFS to tell you what it is doing, what it is seeing, and just why something is wrong
Yes; this is essentially the concern I had about ZFS.
It's a big, complicated, single component; at least with a conventional FS on RAID I've got an abstraction layer that I can debug at.
