Filesystems can get corrupted if the system crashes and does not cleanly close the filesystem first. In your case I'm personally not too sure - some more questions perhaps can help. - Were you using softupdates on the filesystem? - Did the system panic/reboot when the disk crashed without shutting down cleanly? - What version of FreeBSD are you / were you running? > Another thing, Greg, you mentioned that I should have a second plex if I wanted > to protect the data.

If you had configured the subdisks as a concatenated or striped plex then there would most likely be no way to continue with a disk missing unless there existed a second plex with a copy of the data.
