Hi Jeremy, I had a loosely similar problem with my 2009.06 box. In my case (which may not be yours), working with support we found a bug that was causing my pool to hang. I also got erroneous errors when I did a scrub ( 3 x 5 disk raidz). I am using the same LSI controller. A sure fire way to

Hi Jeremy, The ereport.io.scsi.cmd.disk.tran is describing connections problems to the /p...@0,0/pci8086,4...@5/pci1000,3...@0/s...@30,0 device. I think the .tran suffix is for transient. ZFS might be reporting problems with device as well, but if the zpool/zfs commands are hanging, then it

Jeremy, I can't comment on your hardware because I'm not familiar with it. If you have a storage pool with ZFS redundancy and one device fails or begins failing, then the pool keeps going, in a degraded mode but is generally available. You can try setting the failmode property to continue,
