[plug] Ubuntu woes

[Paul Antoine]

Hi Steve,

Are there any messages being generated in the kernel or syslog's? Are 
all the disks in a hardware RAID array?

I have been working on an 8TB server for a client and have experienced a 
similar issue though in my case some of the (brand new!) disks were 
generating i/o errors.

In any case I'd be happy to help if I can.

Paul
