Updated src tree to r220537. Recompiled world, kernel, etc. Installed world, kernel, etc. ZFSv28 patch was not affected. Everything is detected correctly, everything comes up correctly. See a new option (reload) in the RC script for hast. Can create/change role for 24 hast devices simultaneously. Can switch between master/slave modes. Have 5 rsyncs running in parallel without any issues, transferring 80-120 Mbps over the network (just under 100 Mbps seems to be the average right now). Switching roles while the rsyncs are running succeeds without deadlocking (obviously, rsync complains a whole bunch while the switch happens as the pool disappears out from underneath it, but it picks up again when the pool is back in place). Hitting the reset switch on the box while the rsyncs are running doesn't affect the hast devices or the pool, beyond losing the last 5 seconds of writes. It's only been a couple of hours of testing and hammering, but so far things are much more stable/performant than before. Anything else I should test? --=20 Freddie Cash fjwcash@gmail.com
