It had been running r151012 for over a year but was recently upgraded to r151020. I don’t remember the exact timing – but think we did the upgrade, rejoined it to the domain, and let it sit for about a month to see if there were any problems. In this time, everything continued to work fine. However, eventually, I got tired of seeing the “pool needs upgraded” message in the scrub emails, so we did a zpool upgrade, at which point the software that writes to the share started having problems (the developers say with file locking). I still have the r151012 BE, but am uncertain what will happen when I boot back into it – will the pool degrade gracefully to only the features that older release knows about? I’m not certain this is even an OmniOS/ZFS bug, but given that was the only change we can think of during the timeframe when the problem popped up, it seems a possibility – so I thought I’d ask the list if anyone else has seen anything like this or has ideas how to troubleshoot? </pre> </blockquote> <pre wrap="">___ </pre> </blockquote> After an upgrade I had problems with some applications.
