I have not been able to crash or hang the box since applying Mikolaj's patc= h. I've tried the following: - destroy pool - create pool - destroy hast providers - create hast providers - switch from master to slave via hastctl using "role secondary all" - switch from slave to master via hastctl using "role primary all" - switch roles via hast-carp-switch which does one provider per second - import/export pool I've been running 6 parallel rsyncs for the past 48 hours, getting a consistent 200 Mbps of transfers, with just under 2 TB of deduped data in the pool, without any lockups. So far, so good. --=20 Freddie Cash fjwcash@gmail.com
