At LCA 2006 (the Canberra one) Ted T'so talked about performing nightly
read-only fscks on ext3 filesystems, that only update the time-since-fsck
stamp in the superblock (if my memory serves). The fsck would not modify
the filesystem if it was broken, but would report on errors. Additionally
doing a dump of the inode tree to another filesystem was recommended.
I had planned on actually doing this at one point to see if it gave any
benefits, but never got around to implementing a system with these features.
