Raid 0 has the risk of data corruption that usually happens after a certain amount of time. Is using LVM2 for striping safer than raid 0?

Never heard of that. That is whole point of RAID is data intergity( sp? ).

well raid 0 has no additional integrity at all, hence the "0". Where did you read about that corruption stuff? i'd imagine that that really relates to a comparison of raid 0 vs other parity based raid versions, so only what would affect a normal filesystem without raid. in terms of LVM2 as a comparison the risks would still be there at a generic level, and LVM is actually more complex than raid, which, when done through md at least, is nothing more than two generic ext3 (or such) file systems which get overlaid and managed as one. LVM is more complex and more difficult to draw out accurately on a piece of paper...

I've not had any real bad experiences with LVM, only raid, but that's just the odds kicking in i reckon. LVM just gives you much more flexibility... add this drive, remove that one, extend this PV to cover half that drive... as RAID0 does very little it's harder to justify, my main angle for LVM and raid is RAID1+LVM over RAID10.

Brain fart on my part. For some reason I read RAID0, but was thinking mirroring....
