An interesting article I stumbled upon: http://www.unixsheikh.com/articles/battle-testing-data-integrity-verification-with-zfs-btrfs-and-mdadm-dm-integrity.html My take: If you care about your data you should be using ZFS or btrfs. In case of data corruption (system crash, power outage, user error, or even just a HDD "hiccup") plain md without the dm-integrity layer won't even be able to tell which is the good data and will overwrite your good data with bad data. Silently. ZFS appears to be better than btrfs in several ways (features, reliability, speed). Unfortunately you'll need at least an out-of-tree kernel module for that (package zfs-dkms). For only a RAID1-type configuration btrfs might be good enough. Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser
