vzmigrate(8) Containers vzmigrate(8)
NAME
vzmigrate - migrate a container between two OpenVZ servers
SYNOPSIS
vzmigrate [-r|--remove-area yes|no] [--ssh=ssh_options] [--rsync=rsync_options] [--keep-dst] [--online] [-v] destination_address CTID
DESCRIPTION
This utility is used to migrate a container from one (source) Hardware Node (HN) to another (destination) HN. The utility can migrate
either stopped or running container. For a stopped container, simple CT private area transfer is performed (rsync(1) is used for file
transfer). For running containers, migration may be offline (default) or online.
This program uses ssh as a transport layer. You will need to put ssh public key to destination node and be able to connect to node without
entering password.
OPTIONS
-r, --remove-area yes | no
Whether to remove a container area on source HN for the successfully migrated container. Default is yes.
--ssh=options
Additional options that will be passed to ssh while establishing connection to destination HN.
--rsync=options
Additional options that will be passed to rsync(8). You may add options like -z to enable data compression if you are migrating
over a slow link.
--keep-dst
Do not clean synced destination container private area in case of some error. It makes sense to use this option on big container
migration to avoid syncing container private area again in case some error (on container stop for example) occurs during first
migration attempt.
--online
Perform online (zero-downtime) migration: during the migration the container hangs for a while and after the migration it continues
working as though nothing has happened.
-v Verbose mode. Causes vzmigrate to print debugging messages about its progress. Multiple -v options increase the verbosity. The
maximum is 3.
EXAMPLES
Migration of CT 101 to 192.168.1.130 with downtime:
vzmigrate 192.168.1.130 101
Online migration of CT 102 to 192.168.1.130:
vzmigrate --online 192.168.1.130 102
EXIT STATUS
0 EXIT_OK
Command completed successfully.
1 EXIT_USAGE
Bad command line options.
2 EXIT_VE_STOPPED
Container is stopped.
4 EXIT_CONNECT
Can't connect to destination (source) HN.
6 EXIT_COPY
Container private area copying/moving failed.
7 EXIT_VE_START
Can't start or restore destination CT.
8 EXIT_VE_STOP
Can't stop or checkpoint source CT.
9 EXIT_EXISTS
Container already exists on destination HN.
10 EXIT_NOTEXIST
Container does not exists on source HN.
12 EXIT_IP_INUSE
You attempt to migrate CT which IP address(es) are already in use on the destination node.
13 EXIT_QUOTA
Operation with CT quota failed.
