# Longhorn distributed block storage system
|
||||
|
||||
Pull the manifest and apply changes
|
||||
## For users
|
||||
|
||||
You should really avoid using Longhorn as it has over time proven to be
|
||||
unreliable system. Prefer using remote databases in your application via
|
||||
the Kubernetes operator pattern.
|
||||
|
||||
Use Longhorn for applications that need persistent storage, but are unable
|
||||
to provide replication in the application layer:
|
||||
|
||||
* Applications that insist writing into filesystem
|
||||
* Applications that serve Git repositories (eg Gitea)
|
||||
* Applications that check out Git repositories (eg Woodpecker, Drone and CI systems)
|
||||
* Applications that need to use SQLite
|
||||
|
||||
Instead of using built-in `longhorn` storage class, please add new storage class
|
||||
with suitable replication, data locality parameters and reclaim policy
|
||||
[https://git.k-space.ee/k-space/kube/src/branch/master/storage-class.yaml](here)
|
||||
|
||||
Longhorn backups are made once per day and it's configured to be uploaded to
|
||||
the Minio S3 bucket hosted at nas.k-space.ee
|
||||
|
||||
|
||||
## For administrators
|
||||
|
||||
Longhorn was last upgraded with following snippet:
|
||||
|
||||
```
|
||||
wget https://raw.githubusercontent.com/longhorn/longhorn/v1.5.1/deploy/longhorn.yaml -O application.yml
|
||||
wget https://raw.githubusercontent.com/longhorn/longhorn/v1.6.2/deploy/longhorn.yaml
|
||||
patch -p0 < changes.diff
|
||||
kubectl -n longhorn-system apply -f longhorn.yml -f application-extras.yml -f backup.yaml
|
||||
```
|
||||
|
||||
To upgrade use following:
|
||||
|
||||
```
|
||||
kubectl -n longhorn-system apply -f application.yml -f application-extras.yml
|
||||
```
|
||||
|
||||
After deploying specify `dedicated=storage:NoSchedule`
|
||||
After initial deployment `dedicated=storage:NoSchedule` was specified
|
||||
for `Kubernetes Taint Toleration` under `Setting -> General` on
|
||||
[Longhorn Dashboard](https://longhorn.k-space.ee/).
|
||||
Proceed to tag suitable nodes with `storage` and disable Longhorn scheduling on others.
|
||||
Suitable nodes were tagged with `storage` and Longhorn scheduling was disabled on others.
|
||||
|
||||
Refer to `application.yaml` to see how backups are configured.
