Subject:  Does ext4 perform online update of the bad blocks inode?

Does ext4 update the bad blocks inode when a read/write failure is detected in a
mounted filesystem? If not, is safe a daily/weekly "fsck.ext4 -n -c device" on a
mounted filesystem? Would be safe even on a raid volume?

Unfortunately, still no Bad Block Relocation Target for lvm2 so I'm interested
in similar fs features.

Thanks,
Francesco
