Hi all,

I try to make a backup of swift cluster by stopping server and backup all files.
Then I create one more cluster with absolutely the same settings and
restore all files
from backup on it. As result swift is working and  'swift glance list'
gives the same
correct list as before, but 'swift glance download' gives 404 for 2
objects of 3.
This 2 object fully available on original cluster and they id
correctly returned by
'list'. 'info' on them return 404  as well. I try to inspect swift db
but it looks correct
as far as I can tell.

Swift log contains no information about this error, except for 404.

CLI results:

# swift --version
swift 2.4.0

How to investigate this? What files I need to check on disk?
Or update some setting for swift to show me more error information in log?

Thanks
