The same as on the others (WD RE2GP), just with the updated firmware (02.01B02 that is) to get rid of the lcc problem.

JC> http://en.wikipedia.org/wiki/Silicon_Image_Inc.#Product_alerts I knew the card is not top of the line, but I didn't know that it is /that/ bad. When I set up the system 1 or 2 years ago, I just thought it might be nice to be able to use the two extra slots in case of any drives having to be replaced or so and the card was just lying aroung (well, maybe I have an idea now why nobody else wanted to use it :-). I guess I will try to offline the hotspare slot (connected to the mcp55 on the motherboard) and plug the replacement disk in there. Maybe zfs recognizes it and picks up the resilvering there. Otherwise I'll have to look into how to get rid of the degraded resilvering process and restart it with the drive in the other slot.

I use these 8-channel Supermicro-Controller (I think I recommended them some time ago here) with LSI chipset that work really nicely. But the backet does not fit into standard slots and there is no PCI-X version. I would certainly prefer a regular card by Intel. cu Gerrit
