An update on this: I have now turned off the RAID on half of my blades, leaving the other half untouched. After a few days, 3 of those systems still using the RAID have experienced similar fs corruption as reported before, while all the blades wo/ RAID have been running fine. So, that looks like the RAID is indeed to blame and I'll turn it off for all systems now.
