When I issued a ufsdump command to backup an entire file system, I received a warning message that says "directory at inode 704000 vanished". What may be the cause of this and will it pose any problem at subsequent ufsrestore?

Most probrably the warning is telling you that the system state has changed during backup using ufsdump.

Ufsdump will go thru 4 phases.
Phase 1 & 2 will record down directory and files structure and create a backup list to be recorded in the beginning of the tape.

Phase 3 & 4 are the actual writing of data of both directory and files in the tape.

The error message probrably means that the directory was listed to be backup in Phase 1 but activity in your system cased it to be deleted,so ufsdump complains not finding the directory.

Recommended practice is to have no disk activity (probrably going to single user mode) and perform the dump.

You have a corrupted file system, you will nedd to perform a fsck on it. You might loose some of it... Find what is the directory at that inode and try to copy it before doing an fsck on it. You probably won't be able to copy it. you might have to restore it from an older dump ( with no error...)
