[comp.unix.questions] Missing space in root

pjh@mccc.UUCP (Pete Holsberg) (04/12/89)

I run a pair of 3B2/400 (SV R3.1) computers and just noticed a strange
thing.  A variant of df reports that I have used 11421 KB in the root
directory of one machine, and 9832 KB in the root of the other.  I've
added up all the files in root of each machine and the result is far
short of the numbers that bdf reports (eg., for mccc, the toatal is
about 6 MB against the 11421 KB).  I assume that some of the space can
be accounted for by the directory files themselves -- but not 5+ MB
worth!  Can anyone suggest what is happening?  On mccc, / has the
following directories: /bck, /bin, /boot, /dev, /dgn, /etc, /floppy,
/mnt, /install, /lib, /lost+found, /save, and /shlib, plus two other
file systems (/usr and /usr2) on the same machine plus another file
system (/MC3) connected via RFS.

Thanks,
Pete

I would take the machine down to init level 2 (stop RFS) and look
under the RFS mount points. It could be that your network file systems
are hiding local files.

Andy (and others who emailed responses) --

It went away!!  :-(  When I got here this AM, I was greeted by

WARNING:
	hard disk:  drive 0 out of service
	
PANIC: swap segment - i/o error in swap.

Rebooting showed a possibly damaged /usr2, but an fsck repaired it.  I
guess I'd better go shopping for another 72MB HD!  

Eventually, everything rebooted properly and with all file systems
mounted, I now have recovered the missing megabytes.  ????  I'm nervous.

Pete
