Detaching Containers From Caches
Whereas the vzcache utility helps effectively gain disk space both on the Parallels server and
within Containers, there may be situations when it is necessary to detach a Container from its
cache and copy the cached files back to the Container private area. A typical example of this is
migrating a Container to another Parallels server. The migration is not possible if there are links in
the Container private area pointing to the /vz/template/vzcaches directory on the server.
To copy the cached files back to the Container private area, the vzuncache utility is used:
# vzuncache 101 -a
[Optimization messages skipped...]
Container 101 53 magic symlinks to convert
Container 101 will be detached from the following caches:
Cache name Size
dhcp0-84.sw.ru-2005030316237 607972K
Now Container 101 can safely be migrated to another Parallels server. Note that unlike vzcache,
the vzuncache utility shall be called for only one Container at a time. The -a switch tells the utility
to detach the Container from all the cache directories specified in its configuration file as the value
of the VZCACHE parameter.
