I'm trying to bild a storagebox with ZFS. Now I have some problems which seems to be related to ZFS. Perhaps after adding disks to an existing pool, all consoles trying to execute a command with I/O operations freezes. Only sometimes I get a panic. I played around with the tuning variables, proposed in http://wiki.freebsd.org/ZFSTuningGuide but didn't help. The box is running -CURRENT amd64/SMP in a GENERIC configuration. Last cvsup and build was "Fri Jun 22" I also tried with i386 with and without SMP. I collected some Information and uploaded it to https://jschmidle.org/upload/ In "panic1" you can see a whole system-bootup resulting in a Panic. "panic2" is just another lockup during bootup. "areca" contains the information about the raid controller in use. in "dump", I tried to create a coredump during a lockup. "alltrace", "witness", "ps" also have been created during the lockup. "sysctl" contains the current settings. Can anyone recognize where the problem is coming from or is additional information needed? Jan
