Hello, I decided to give ZFS ZRAID2 a shot after getting fed up with some legacy hardware RAID cards that don't properly perform, or at all, patrol-reads + consistency checking. So... I can't seem to figure out the proper way to replace a dead drive in a running system with SCSI+SES enclosure. I tried: zpool detach zroot baddrive camcontrol stop baddrive At this point when I pull the drive out, I get bus reset errors, etc... I will go into details after someone confirms whether the above 2 steps suffice to pull a dead/malfunctioning drive out from SES enclosure or am I missing something? I tried to simulate drive failure by pulling 2 out of 3 ZRAID2 drives. The first drive pull went smoothly. System noticed drive disconnected and stopped using it. The 2nd drive pull resulted in bunch of errors and system froze completely. I can't pull 2 drives out in ZRAID2 system and expect the machine to continue to function? what am I missing :\ PS: I couldn't find dedicated FreeBSD ZFS email list, is there one? Thank you very much! Simon
