Re: RAID5 recovery trouble, bd_claim failed?

[Nate Byrnes <nate@qabal.org>]

Hi All,
    I'm not sure that is entirely the case. From a hardware perspective, 
I can access all the disks from the OS, via fdisk and dd. It is really 
just mdadm that is failing.  Would I still need to work the jumper issue?
    Thanks,
    Nate
