Does that mean, that XFS could have problems with SW RAID rebuild
after a disk failure? After I get things running, I'm going to test what
happens when I remove a disk from hotswap and plug it back again in live
system. I need to have that working before putting the system to use (even
if it requires to spend some $$ on some RAID hardware).
