I just moved /usr/ to a new partition. Everything went smoothly, and the
new /usr is mounted. However, disk usage is dramatically higher on the
new /usr than on the old one. I have confirmed (using 'find . -xtype f
- -exec cmp {} /mnt/tmp/{} \;') that the directory structures are identical
between the two filesystems. However, the files on the new filesystem are
bigger. Here's what I mean:
ant:~$ df /usr /mnt/tmp
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda10 1512832 688712 747272 48% /usr
/dev/sda11 2734835 595615 1997808 23% /mnt/tmp
Notice that the 'Used' column is greater on /usr than on /mnt/tmp (old
usr). Doing something like du -sk /usr/sbin and du -sk /mnt/tmp/sbin
shows that the contents of the sbin subdirectory are slightly larger on
the new /usr...that's the case with all the subdirectories.
I suspect this problem has something to do with 'sparse files'. The
command I used to copy the filesystem was:
cd /usr && tar cpf - . --exclude local --exclude lost+found | (cd
/mnt/tmp/ && tar xpf -)
However, I saw the exact same behavior in an earlier attempt using
'cp -ax'
Has anybody got any idea why this new filesystem is "bigger" than the
orginal? What can I do to fix it?
TIA!
