Mostly customers thinking they fully understand the thousands of parameters in ZFS. There was a _very_ nasty bug in the ZFS L2ARC that took out a few PB at a couple of large installations. This was back in 2012/2013 when multiple PBs was very expensive. Was a case of ZFS putting data from the ARC into the pool after the ZIL/SLOG had been flushed. |
