Is there something unique about the hardware that causes this? It really shouldn't happen - that's what the journal in both xfs and ext4 is for - to replay after a power failure and keep metadata consistent. What kind of corruption are you seeing? Generally if a power loss causes filesystem corruption on either xfs or ext4, it's due to a storage problem. (Unless by corruption you mean lost buffered IOs, which is really an application issue.) > As most of you probably know, it is much, much easier to repair a > file system error with other file systems, ext4, for example.
