# Removing secondary Geo nodes **[PREMIUM ONLY]**
|
||
|
|
|
||
|
|
**Secondary** nodes can be removed from the Geo cluster using the Geo admin page of the **primary** node. To remove a **secondary** node:
|
||
|
|
|
||
|
|
1. Navigate to **Admin Area > Geo** (`/admin/geo/nodes`).
|
||
|
|
1. Click the **Remove** button for the **secondary** node you want to remove.
|
||
|
|
1. Confirm by clicking **Remove** when the prompt appears.
|
||
|
|
|
||
|
|
Once removed from the Geo admin page, you must stop and uninstall the **secondary** node:
|
||
|
|
|
||
|
|
1. On the **secondary** node, stop GitLab:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo gitlab-ctl stop
|
||
|
|
```
|
||
|
|
1. On the **secondary** node, uninstall GitLab:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
# Stop gitlab and remove its supervision process
|
||
|
|
sudo gitlab-ctl uninstall
|
||
|
|
|
||
|
|
# Debian/Ubuntu
|
||
|
|
sudo dpkg --remove gitlab-ee
|
||
|
|
|
||
|
|
# Redhat/Centos
|
||
|
|
sudo rpm --erase gitlab-ee
|
||
|
|
```
|
||
|
|
|
||
|
|
Once GitLab has been uninstalled from the **secondary** node, the replication slot must be dropped from the **primary** node's database as follows:
|
||
|
|
|
||
|
|
1. On the **primary** node, start a PostgreSQL console session:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
sudo gitlab-psql
|
||
|
|
```
|
||
|
|
|
||
|
|
NOTE: **Note:**
|
||
|
|
Using `gitlab-rails dbconsole` will not work, because managing replication slots requires superuser permissions.
|
||
|
|
|
||
|
|
1. Find the name of the relevant replication slot. This is the slot that is specified with `--slot-name` when running the replicate command: `gitlab-ctl replicate-geo-database`.
|
||
|
|
|
||
|
|
```sql
|
||
|
|
SELECT * FROM pg_replication_slots;
|
||
|
|
```
|
||
|
|
|
||
|
|
1. Remove the replication slot for the **secondary** node:
|
||
|
|
|
||
|
|
```sql
|
||
|
|
SELECT pg_drop_replication_slot('<name_of_slot>');
|
||
|
|
```
