Then maybe You see a scenario where that feature would actually prevent db corruption, while I have not yet found a realistic one. Instead, what gave me headaches is that ZFS might take a single tablespace (=pool) offline with the cluster continuing to run - and I am not sure if the db is supposed to survive that (mine did, after I had hit the power button in horror), nor is it easy to protect from that. Anyway, I can now switch that feature off per local patch, which is the second-best solution. ! Oooh ... it looks like some of the encryption code paths have neglected ! to call gss_release_buffer. Will fix, thanks for the report! Great! So I assume I don't need to send a bug report I had prepared interim. Feel free to ask me for anything that might be still needed. cheerio, PMc
