ext3 partition problems w/Apple Xserve RAID

[Ionel GARDAIS]

Hi there,

I'm running the same kind of configuration (RHEL ES 4 on a PowerEdge 
2950 with a QLE2460 connected to a SanBox 5200 with 2 XServe RAID 10.5TB).
The four 4.5TB slices are directly formated in ext3, no partitions were 
created.

Should I expect to get some data corruption on power failure ?

Thanks,
Ionel
