After upgrading from previous versions of Parallels Virtuozzo Containers (PVC)/ Parallels Server Bare Metal (PSBM) to Parallels Cloud Server (PCS), the default container layout remains as VZFS4.
In order to convert existing containers to the new container-in-a-file format (also known as "ploop"), run the following command:
# vzctl convert CTID --velayout 5
NOTE: the conversion works in online mode since PCS 6.0 update 4. Previously, it was necessary to stop the container before converting it to ploop.
In order to get all new containers created in ploop format by default, follow these steps:
/etc/vz/vz.confand set VEFSTYPE to ext4:
# grep VEFSTYPE /etc/vz/vz.conf VEFSTYPE="ext4"
Rebuild the OS templates cache:
# vzpkg update cache
NOTE: This operation may take a while depending on number of OS templates installed on your server.
