Dear Samba-
We're using the virtualization application openVZ to run small web
services for researchers. Unlike other virtualization software, openVZ
uses the host file system for the guest OS; essentially the root file
system of the guest is a chrooted subdirectory on the host.

When openVZ migrates a guest between two host machines it uses rsync
to transfer the files. Unfortunately, this causes samba to panic and
not accept any new connections (established connections are OK). In
the logs I get "
tdb(/var/cache/samba/ntforms.tdb): tdb_reopen: file dev/inode has
changed!" . Of course the inode changed, but does it need to panic?
Is there a workaround?
