Hi:

Recently I heard of the so called "write hole" problem of raid5 in
Linux software raid. I use ext4 filesystem on my NAS, which assembles
data disks using Linux software raid. So I wonder how safe my such
system!

If the "write hole" is inevitable, will it result in the corruption of
ext4 filesystem?
