I've got the same problems on a Dell PowerEdge T110 with four 500.1 GB disks from Seagate (ST3500320NS) when trying to combine two of them to a RAID1.
I remember that there was a error in dmesg after falling back to the initramfs console about the ext4 filesystem (something with unexpected size) and a message like
md0p1 bad geometry block count exceeds size of device
(restored from my search history today).
I post the exact error message tomorrow, when I have access to the server again, if you like. I may also try some of the workarounds in order to get the server up and running tomorrow but since it's a replacement for an existing server I could delay the workarounds for some days in order to assist in debugging this issue.
