Hi, I spent the larger part of the weekend finding out why my ceph daemons were crashing without much logging, tracebacks or cores... Turns out I got bitten by the fact that 11.1 does introduce fdatasync, which is used by ceph. Compilation is on a server that I also test the RC's on, so there fdatasync was available. But the jails were not upgraded, and missed fdatasync. So that is definitely a pilot error on my end. But it would have helped me enormously if the late binding error got logged in something like /var/log/messages.... Especially since these are daemons, which can for quite some time before a call to fdatasync is made, it took me quite some time to actually run the daemon in the foreground and see this little pesky line about missing fdatasync. Would it be hard to add this to the code, or did I just mis other signs? --WjW
