It's certainly suspicious but without actually understanding what is causing the problem, hard to be sure if there is a relation. I'm struggling to understand how "ls" can show a date in 2003 for a file, while dump thinks that the inode has changed since your level 0 a few days ago. I'm no expert on the filesystem, but that's just weird.

What does ls -lsak /home/.snap show? I know there can be issues with snapshots in the 5 series and having more than one snapshot can be a bad idea. I don't think that's it because your dump -S without -L showed pretty much the same as with -L, but just in case. If you do find any snapshots (I believe dump would leave one called dump_snapshot or .dump_snapshot or something obvious if it gets interrupted (by a power failure, for example) then you can delete with rm. I don't hold out much hope but it's easier than a dump/restore). If no-one else replies here with bright ideas, you could also try posting to maybe freebsd-hackers or freebsd-fs; http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/eresources.html#ERESOURCES-MAIL Good luck. If you try the newfs, please let us know how it turns out. --Alex
