Question : mdadm: Cannot set device size/shape for /dev/md0: Device or resource busy

Hi people,

I have a software RAID 5 array setup using palimpsest in ubuntu 10.04. It currently has 4 1TB drives configured in RAID 5.

I got a another 1TB hard drive, popped it in the PC, it detected fine, no problems, so far... I then proceeded to run palimpsest and went to my array > edit components > expand array > selected the new drive and got this error:

"Error expanding array: helper script exited with exit code 1: mdadm: added /dev/sdb1
mdadm: Cannot set device size/shape for /dev/md0: Device or resource busy"

Any ideas what this means or what is causing it?

Thanks.

This should do:
Hope your ClassLn table has ClassId in it.

                       
             SELECT em.Name, cs.Description, cl.StartDate, cl.EndDate
FROM Employee em inner join Class cs on em.ClassId = cs.ClassId
inner join ClassLn cl on cl.ClassId = cs.ClassId
