[OpenIndiana-discuss] Diagnosis help needed

[michelle]

The motherboard is a Gigabyte GA-H55M-UD2H and has five SATA sockets, 
two IDE and one E-sata.

The SATA are, I believe, Intel.

The mb has five internal sata - two are rpool which are SSDs with plenty 
of space on them.

The other three are given over to a "tank" mounted at /mirror.

The external toaster is a Sharkoom Quickport Duo II, where drive  1 is 
connected via E-sata and, when I connect the second, it is via USB 
because I only have one e-sata port.

I believe that disconnecting the USB has resulted in stopping the IRQ 
resource problem, but now I am having this...

The set is usually automatically scrubbed once a month.

I have removed about 200 gig of data and it seems to be stable-ish.

I'll begin another scrub of the tank now. It will likely take 10 hours.
