First, ufsrestore recovers files from a tape prviously written by ufsdump. It's a cool program, but it won't move stuff out of lost+found.

You can manually move things from lost+found by doing stuff like "mv /lost+found/143226 /etc/passwd" or whatever. But moving a file from one point to another point in the same filesystem never increases its size. If your disk is 16% full now, after the moves it will still be 16% full. If your disk was previously 63% full, then you are missing lots of stuff.

I never try to fix a filesystem that is this badly damaged. I would newfs it and completely reload from backup. Unless it is root, it which case I would reinstall the OS. Sorry for the bad news.

You would think that the superblock at least would be ok after a "fsck -y"; but I believe you, because the same thing happened to me a few weeks ago only on a SunOS 2.5.1 box. It may be that Sun's fsck is less than robust.

CLRI(8) 						    BSD System Manager's Manual 						   CLRI(8)

NAME
clri -- clear an inode SYNOPSIS
clri special_device inode_number ... DESCRIPTION
Clri is obsoleted for normal file system repair work by fsck(8). Clri zeros out the inodes with the specified inode number(s) on the filesystem residing on the given special_device. The fsck(8) utility is usually run after clri to reclaim the zero'ed inode(s) and the blocks previously claimed by those inode(s). Both read and write permission are required on the specified special_device. The primary purpose of this routine is to remove a file which for some reason is not being properly handled by fsck(8). Once removed, it is anticipated that fsck(8) will be able to clean up the resulting mess. SEE ALSO
fsck(8), fsdb(8), icheck(8), ncheck(8) BUGS
If the file is open, the work of clri will be lost when the inode is written back to disk from the inode cache. 4th Berkeley Distribution April 19, 1994 4th Berkeley Distribution
