Reclaiming disk space after unlinking dir

I am running Solaris 2.5 using the GNU fileutils.  I was
id root (unfortunately) when I did a typo and did rm -rd
instead of rm -rf.  Now the directory is gone, but my disk
did not reclaim any more space.  I have done fsck several
times but it appears everything is fine.  Any ideas on how to reclaim the space besides remaking the fs and restoring?

The man page of rm suggests starting with fsck.

Did you try giving the "-o f" option to fsck?  Solaris-2.5 stores the filesystem state in the superblock, and if the state is "clean," fsck won't check.  The fsck man page says "-o f" forces fsck to check even if it thinks it doesn't need to.  (BTW, I always thought the option was simply "-f"; you might want to try that too, if "-o f" doesn't force the check.)

I'd expect the directory to end up in the lost+found directory at the top of the partition; the name will be the inode number that the directory had before you unlinked it.  BTW, it's possible that it's already there -- fsck won't "reclaim" space; it'll only find filesystem problems and repair them to the best of its ability.  This generally results in files and directories that have gotten halfway-deleted or otherwise lost, getting restored in the lost+found directory.

Thanks for your answer!  I had thought that fsck would ask me yes or no before it did anything to all of those files in the directory, but sure enough, there they all were in lost+found.  I feel really stupid now, but I don't normally go around unlinking directories! :)  Thanks!!!
