I have gotten several replies to my query as to where over 10 Mbytes of
disk space have disappeared to. Most related to a process creating a
file, rm the file, but the process still fills the area. Others related
to similar 'hidden' files. One wondered if I tried it as root? Hmmmm . .
. of course . . .
Anyway, I brought down the system, brought up the miniroot off of tape and
fsck'ed the partition . . . I did find @4 Mbytes this way.
Under the miniroot, the root partition, I mounted the root partition of
this disk as /a and the /usr partition as /d (so I could use du). From
df:
Filesystem kbytes used avail capacity Mounted on
/dev/xy0a 30191 21692 5479 80% /a
/dev/xy0d 132904 115730 3883 97% /d
BUT, when I did a du on these 2 partitions, I get a WILDLY different
answer (from the last line):
13201 /a
115730 /d
Hmmmm . . . the /d 'du' matches the 'df' estimation, but the /a 'du' is
still almost 8 Mbytes off!!!!!
Now, mind you this was NOT on a working disk, I had installed the miniroot
and was mounting these partitions (I was NOT using the root partition off
of the disk). I thought I might have screwed up the partitioning (I
DIDN'T reformat when I just moved up from 4.0 to 4.1.1, just had
suninstall do it's newfs thing), but wouldn't a screwed up partition shown
up in 4.0???:
Current partition table (original xy0):
partition a - starting cyl 0, # blocks 64320 (64/0/0)
partition b - starting cyl 64, # blocks 196980 (196/0/0)
partition c - starting cyl 0, # blocks 1743675 (1735/0/0)
partition d - starting cyl 260, # blocks 283410 (282/0/0)
partition e - starting cyl 542, # blocks 37185 (37/0/0)
partition f - starting cyl 579, # blocks 423105 (421/0/0)
partition g - starting cyl 1000, # blocks 510540 (508/0/0)
partition h - starting cyl 1508, # blocks 228135 (227/0/0)
I'm baffled . . . Any help? I never had this problem with OS 4.0, just
since I upgraded to OS 4.1.1 . . . Thanks . . .
