Good news for you guys, bad news for us -- we were building HA storage on vmware for a client and can now replicate the crash on demand. I'll be posting details when I get home to my PC tonight, but this hopefully is enough to replicate the crash for any curious followers: > > ESXi 5 > 9 or 9-STABLE > HAST > 1 cpu is fine > 1GB of ram > UFS SUJ on HAST device > No special loader.conf, sysctl, etc > No need for VMWare tools > Run Bonnie++ on the HAST device > > We can get the crash to happen on the first run of bonnie++ right now. I'll post the exact specs and precise command run in the PR. We found an old post from 2004 when we looked up the process state obtained from CTRL+T -- flswai -- which describes the symptoms nearly perfectly. > > http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2004-02/0250.html > > Hopefully this gets us closer to a fix... Sorry, I just now saw this. :( Are you still seeing this, and if so can you get a crashdump? Also, I'm curious if you only see this with SUJ or if plain UFS+SU works fine? -- John Baldwin
