Container migration from Virtuozzo containers 4.0 or 4.6 to Virtuozzo (formerly Parallels Cloud Storage)

  • Updated
Applies to:
  • Virtuozzo Server 6.x

Symptoms

There are cases when a container's old layout cannot be converted to ploop on a migration from Virtuozzo containers 4.0 or 4.6 to a Virtuozzo location:

1363039660: 1363039660: error [-64] : Note: During migration, the utility will convert the Container to a new ploop-based layout.
1363039660: Note: During migration, the utility will convert the Container to a new ploop-based layout.
1363039660: Can't move/copy CT#CTID - CT#CTID, [], [] : Note: During migration, the utility will convert the Container to a new ploop-based layout.
1363039660: close channel

Resolution

To resolve the issue, follow these steps:

  1. Prepare the container for migration to ensure all packages from the template area are transferred properly. This is described in the KB article Preparing VZFS containers for migration.

  2. Stop the container and migrate it to the local partition on Virtuozzo:

    [root@pvcfl40 ~]# vzmigrate root@10.10.10.10 CTID --new-private=/vz/private2/CTID

    If the stage fails, copy container's private area (and the template area, if needed) to the destination node manually with rsync.

  3. Convert the container to ploop:

    [root@pcs]# vzctl convert CTID

  4. Move the container's private area to Pstorage:

    [root@pcs]# vzmlocal CTID::/vz/private/CTID:

After taking these steps, the container should work on Virtuozzo storage without problems. Please also check the Odin end of life policy.
