hammer upgrade changes md5 checksum

[Michael Neumann]

Hi,

I did a "hammer mirror-copy /master /slave", then compared a folder
inside of /master with the same folder on /slave:

  cd /master
  tar cf - DIR | md5     # 9472f...

  cd /slave
  tar cf - DIR | md5     # 9472f...

They both have the same md5 checksum. Great!

Now I upgrade the /slave:

  hammer pfs-upgrade /slave

and get a different checksum:

  cd /slave
  tar cf - DIR | md5     # 3613c...

If I downgrade again, I get the same checksum as before (9472f...).

Hm, just curious why this happens and if this might be a bug?

Regards,

  Michael
