[Gluster-users] gluster 3.2.0 - totally broken?

[Anand Avati]

Udo,
 Do you know what kind of access was performed on those files? Were they
just copied in (via cp), were they rsync'ed over an existing set of data?
Was it data carried over from 3.1 into a 3.2 system? We hate to lose users
(community users or paid customers equally) and will do our best to keep you
happy. Please file a bug report with as much history as possible and we will
have it assigned on priority.

Thanks,
Avati
