Note

This documentation is for OMERO 5.2. This version is now in maintenance mode and will only be updated in the event of critical bugs or security concerns. OMERO 5.3 is expected before the end of 2016.

Moving the data repository

It may be necessary to move either the whole OMERO data directory or only the Managed Repository to a new location on the file system. This should be done with care following the steps below.

Warning

Before moving OMERO data it is wise to ensure that both the data and the database are fully backed up. See OMERO.server backup and restore.

The current location of the data repositories can be found using the omero fs repos command:

$ bin/omero fs repos

 # | Id | UUID                                 | Type    | Path
---+----+--------------------------------------+---------+-----------------------------------------
 0 | 1  | 309ea513-a23c-48d1-abd2-9ceed1b3ffa4 | Managed | /Users/omero/var/omero/ManagedRepository
 1 | 2  | ScriptRepo                           | Script  | /Users/omero/dist/lib/scripts
 2 | 3  | 3ec8c878-c776-48a3-b57e-2a11b0c97045 | Public  | /Users/omero/var/omero
(3 rows)

Note

This command can be slow, omero config get can also be used to determine if omero.data.dir or omero.managed.dir have non-default values.

Moving the OMERO data directory

If the Managed Repository is within the OMERO data directory and the whole data directory is to be moved then the following steps should be used:

bin/omero admin stop
bin/omero config set omero.data.dir NEW
mv OLD NEW
bin/omero admin start

Warning

The use of omero config set is absolutely necessary here. The steps: omero admin stop, mv, omero admin start without omero config set could lead to an unstable situation.

For example, moving the OMERO data directory from /Users/omero/var/omero to /Volumes/omero:

$ bin/omero admin stop
...
$ bin/omero config set omero.data.dir /Volumes/omero
$ mv /Users/omero/var/omero /Volumes/omero
$ bin/omero admin start
...
$ bin/omero fs repos

 # | Id | UUID                                 | Type    | Path
---+----+--------------------------------------+---------+---------------------------------
 0 | 1  | 309ea513-a23c-48d1-abd2-9ceed1b3ffa4 | Managed | /Volumes/omero/ManagedRepository
 1 | 2  | ScriptRepo                           | Script  | /Users/omero/dist/lib/scripts
 2 | 3  | 3ec8c878-c776-48a3-b57e-2a11b0c97045 | Public  | /Volumes/omero
(3 rows)

Moving the Managed Repository

If the Managed Repository is in a separate location from the OMERO data directory or only the Managed Repository is to be moved then the following steps should be used:

bin/omero admin stop
bin/omero config set omero.managed.dir NEW
mv OLD NEW
bin/omero admin start

Warning

The use of omero config set is absolutely necessary here. The steps: omero admin stop, mv, omero admin start without omero config set could lead to an unstable situation.

For example, moving the Managed Repository from /Users/omero/var/omero/ManagedRepository to /Volumes/imports/ManagedRepository:

$ bin/omero admin stop
...
$ bin/omero config set omero.managed.dir /Volumes/imports/ManagedRepository
$ mv /Users/omero/var/omero/ManagedRepository /Volumes/imports/ManagedRepository
$ bin/omero admin start
...
$ bin/omero fs repos

 # | Id | UUID                                 | Type    | Path
---+----+--------------------------------------+---------+-----------------------------------
 0 | 1  | 309ea513-a23c-48d1-abd2-9ceed1b3ffa4 | Managed | /Volumes/imports/ManagedRepository
 1 | 2  | ScriptRepo                           | Script  | /Users/omero/dist/lib/scripts
 2 | 3  | 3ec8c878-c776-48a3-b57e-2a11b0c97045 | Public  | /Users/omero/var/omero
(3 rows)

Note

If omero.managed.dir is not set then the location of the Managed Repository will be determined by omero.data.dir and the OMERO directory should only be moved as a whole.

If the Managed Repository needs to be moved to a location other than that set by omero.data.dir, to a location outside of the OMERO data directory, for example, then omero.managed.dir must be set.

If omero.managed.dir is set then the Managed Repository and the OMERO data directory should be treated independently and thus be moved separately if necessary.
