I was trying to tar a bunch of stuff off a USB backup disk onto the new machine, and it suddenly started throwing all sorts of errors and couldn’t read any drives, not even the root drive to find the shutdown command.
First thing I’m going to check is moving the drives around, because I accidentally put the two new drives in the third and forth slots instead of one and two, so I’m going to fix that. If that doesn’t help, then I’m going to just turn of the Adaptec RAID controller and try a software RAID. If that doesn’t work, I don’t know what I’m going to do. Probably return the hardware and start again.
After reading http://permalink.gmane.org/gmane.os.openbsd.misc/170601 http://marc.info/?l=openbsd-misc&m=125783114503531&w=2 and pointing customers to http://www.cisco.com/en/US/ts/fn/632/fn63267.html and http://www.cisco.com/en/US/ts/fn/631/fn63163.html in my job my trust in hardware raid is … low. (and the last two are for IBM cards, not even the Adapted quality stuff)
I would go for software raid every time.
I don’t consider the DELL CERC to be hardware-raid, I think the PERC is hardware-raid. CE=costeffective, PE=performanceeffective
I’ve seen things you people wouldn’t believe, “things” being combinations of adaptec-controllers and operating systems. And i’m talking about air traffic control, not about a webserver who does a little xen on the side.
Hardware-RAID can be useful if you’re running operating systems who do not have a __working__ software-raid. It take a pci/pcie-slot but can be moved more easily than software-raid.
