I am not familiar at all with I2O and don't have the hardware to
reproduce your issue, so we are going to need your help to solve this!

After reading the I2O FAQ [1] it seems that the second path is only
accessing the first disk instead of the whole RAID array:
What are the various modules for?
[...]
I2O Block OSM (i2o_block):
This is the disk driver, which let you access your RAID array, or if
you don't have a RAID array configured to the single disks. You only
have access to the disks through this driver!
I2O SCSI OSM (i2o_scsi):
This driver let you direct access to the disks. NEVER use this driver
to mount a filesystem or so. If you do so, you could destroy your
data. Only use this driver, to monitor your disks for failure. You
could use the smartmontools to do so.
[...]
The data for your /boot partition are probably out of sync now. :(
Does /dev/sda1 exists on the system? What error message is printed when
you try to mount it? Is there any strange entry that shows up in kernel
messages (dmesg)?
Cheers,
