Scary stories of ZFS? I thought it was the pinnacle of file systems in terms of reliability.
- magicalhippo 6y agoI mean there are some people who have lost ZFS pools or a lot of data. But for each one of those, there are tons more that have lost entire hardware RAIDs. There's also tons more of those that had some horrible error and imagined their ZFS pool was gone for sure, only to find they just lost a couple of files, if anything at all.
- deelowe 6y agoThe only issues I've had are with fragmentation and worrying about losing a disk during rebuilds.
- dehrmann 6y agoI think this has been fixed, but at one point, I used a log device with a one-time encryption key, thinking I didn't care that much about the data if there's a power loss. For the most part, ZFS didn't care either, but what it did care about was not mounting a pool with a missing disk. I had to edit metadata on the pool so it would mount with a different log device. Tools for this didn't exist--I was reading specs and source code, learning how ZFS know which devices belong in a pool.
