This looks to me like the culprit: for trying to probe other OSes,
read-only mounts are performed. But here it looks like os-prober didn't
know about the RAID array, and tried to mount devices separately, the
result is that the EXT3-fs driver thinks it is a bit broken, and tries
to _fix_ it, i.e. write things on the volume!

Unfortunately, there doesn't seem to be any option for disabling that:
ext3 disables it only if the device itself is read-only...
