run du on both filesystems and compare the results.
OK, just because I am curious more then think there is a problem, and
because I am still puzzle from what Otto and Ted said, here is what I
did and the answer to question from Otto as well.
- Both system run 3.8. (www1 was running 3.6 and updated to 3.7, then
3.8 all good following strict step from Nick in the FAQ). www2 was a
full clean install from scratch, full wipe out, not an upgrade.
- There isn't any hard or soft link in that section.
- On the blocksize Otto said/asked if I play with it. No, never did,
always did fresh install by default until this time when I try the
upgrade from Nick as this www1 was a lots of work to do fresh, but I may
just redo it to see.
Then as there is a lots of files and comparing them manually is really a
lots of work, I use rsync 2.6.6 to mirror them:
www1# pkg_info | grep rsync
rsync-2.6.6 mirroring/synchronization over low bandwidth links
www2# pkg_info | grep rsync
rsync-2.6.6 mirroring/synchronization over low bandwidth links
Then, I use rsync and change the setup to allow to log in and run it as
root so that no restrictions would be there in anyway as below to be
sure I have a full identical copy of all the files just like this:
rsync -e ssh -auqz --delete /var/www/sites/ [EMAIL PROTECTED]:/var/www/sites
Then I did:
du -h /var/www/sites on www1 and get 3.9G /var/www/sites
du -h /var/www/sites on www2 and get 7.7G /var/www/sites
Also remember that www1 was the one upgraded, and www2 fresh new install.
Now I continue to look but I am not sure what else I can do to be 100%
sure that all the files are identical before comparing them.
I am still comparing the results from du, but that's huge!
So, may be this test is not a valid one, but then why not?
It is interesting however to say the less.
Now, to push the issue even more, I did this with a third server from
the www1 again:
rsync on it
www3# pkg_info | grep rsync
rsync-2.6.6 mirroring/synchronization over low bandwidth links
Then mirror it:
rsync -e ssh -auqz --delete /var/www/sites/ [EMAIL PROTECTED]:/var/www/sites
Then same, I did:
du -h /var/www/sites on www1 and get 3.9G /var/www/sites
du -h /var/www/sites on www3 and get 7.7G /var/www/sites
The only difference in hardware setup is that both www2 and www3 have
their own drive for that mount point where www1 does not and run i386
oppose to AMD64.
www1# df | grep /var/www/sites
www1# df | grep /var
/dev/wd0e 25799860 4905500 19604368 20% /var
/dev/wd0f 1030550 1552 977472 0% /var/qmail
www2# df | grep /var/www/sites
/dev/wd1a 20640174 8495528 11112638 43% /var/www/sites
www3# df | grep /var/www/sites
/dev/wd1a 20640174 8024648 11583518 41% /var/www/sites
So, the www1 have to have even more stuff on the drive compare to www2
and www3, but show much less.
So copying from www1 to www2 and to www3 give the same results and www2
and www3 match very well, but www1 still show much less for sure.
I am very puzzle at best.
