[wellylug] Blocks count discrepancy fdisk & df

[Carl Turney]

Hi,

I have a weird symptom on my system.  Here are the fdisk and df reports. 
Take particular note of the massive difference between hda3 total blocks
counts between the two, unlike for hda1 or hda2.

fdisk says ...

Disk /dev/hda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1   *           1          13      104391   83  Linux
/dev/hda2              14         138     1004062+  82  Linux swap / Solaris
/dev/hda3             139        9729    77039707+  83  Linux

df says ...

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda3             37334192  20044920  15392800  57% /
/dev/hda1               101086     13044     82823  14% /boot
tmpfs                   257980         0    257980   0% /dev/shm

How did I get this?  Well, I had an 80gb ide hard disk with a ~40GB LINUX
root in partition #3 and an unused ~40GB Windows in partition #4.  I
mirrored the #3 LINUX partition onto a normal backup hard disk (using
rsync - with success, as usual).  Then I deleted partition #3 and #4 and
created one big LINUX partition #3.  I "restored" from the backup using
the following tar command:
tar lcpf - . | ( cd /mnt/newroot; tar xpf - )
/mnt/newroot being the mount point for my newly created/expanded partition

Naturally, I rebooted immediately after repartitioning, relocated physical
original/backup disks as necessary, etc.

Everything works fine.  All apps and data accessible etc.  BUT I AM VERY
CONCERNED ABOUT THE CAUSE, POSSIBLE IMPLICATIONS, AND SOLUTION FOR THE
BLOCKS COUNTS DISCREPANCY.

Thanks VERY much, anyone who can help.
