Move a Meta2 Service
Preparation
Find information about the container you want to move.
By running openio container locate <container> you will get the list of all meta2 service addresses and base names.
You can get list of containers using openio container list.
Launch mover
Since openio-sds 5.0.0, there is a CLI to move the meta2 bases of a container.
You can move the container by running openio-admin container move,
with the name of the container (alternatively, instead of the name of the
container, you can use the option --cid and the name of the base),
and the meta2 service source of this container.
# openio-admin container move mycontainer --src 127.0.0.1:6018 +-------------+--------------------------------------------------------------------+----------------+----------------+--------+--------+ | Container | Base | Source | Destination | Status | Errors | +-------------+--------------------------------------------------------------------+----------------+----------------+--------+--------+ | mycontainer | 594C8B26EA13E562391013AE6FC360C2C1691F314164DD457EF583B16712E360.1 | 127.0.0.1:6018 | 127.0.0.1:6017 | OK | None | +-------------+--------------------------------------------------------------------+----------------+----------------+--------+--------+
The destination service is automatically selected. The command will return the bases moved.
Move to a specific destination
You can specify a destination where you want to move your container. Add the address of a destination service as a parameter; if the destination isn’t free or up, an error will occur.
# openio-admin container move mycontainer --src 127.0.0.1:6017 --dst 127.0.0.1:6018 +-------------+--------------------------------------------------------------------+----------------+----------------+--------+--------+ | Container | Base | Source | Destination | Status | Errors | +-------------+--------------------------------------------------------------------+----------------+----------------+--------+--------+ | mycontainer | 594C8B26EA13E562391013AE6FC360C2C1691F314164DD457EF583B16712E360.1 | 127.0.0.1:6017 | 127.0.0.1:6018 | OK | None | +-------------+--------------------------------------------------------------------+----------------+----------------+--------+--------+
With a destination not free or up, the command returns:
# openio-admin container move mycontainer --src 127.0.0.1:6018 --dst 127.0.0.1:6016 +-------------+--------------------------------------------------------------------+----------------+----------------+--------+----------------------------------------------------------------------------------------------------+ | Container | Base | Source | Destination | Status | Errors | +-------------+--------------------------------------------------------------------+----------------+----------------+--------+----------------------------------------------------------------------------------------------------+ | mycontainer | 594C8B26EA13E562391013AE6FC360C2C1691F314164DD457EF583B16712E360.1 | 127.0.0.1:6018 | 127.0.0.1:6016 | error | Destination service is already used (peers=['127.0.0.1:6018', '127.0.0.1:6019', '127.0.0.1:6016']) | +-------------+--------------------------------------------------------------------+----------------+----------------+--------+----------------------------------------------------------------------------------------------------+
