**This guide explains how to migrate to 0.7 if you have an existing 0.6 cluster.
|
|
We don't recommend trying to migrate to 0.7 directly from 0.5 or older.**
|
|
|
|
**We make no guarantee that this migration will work perfectly:
|
|
back up all your data before attempting it!**
|
|
|
|
Garage v0.7 introduces a cluster protocol change to support request tracing through OpenTelemetry.
|
|
No data structure is changed, so no data migration is required.
|
|
|
|
The migration steps are as follows:
|
|
|
|
1. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`,
|
|
check the logs and check that all data seems to be synced correctly between
|
|
nodes. If you have time, do additional checks (`scrub`, `block_refs`, etc.)
|
|
2. Disable API and web access. Garage does not support disabling
|
|
these endpoints but you can change the port number or stop your reverse
|
|
proxy for instance.
|
|
3. Check once again that your cluster is healty. Run again `garage repair --all-nodes --yes tables` which is quick.
|
|
Also check your queues are empty, run `garage stats` to query them.
|
|
4. Turn off Garage v0.6
|
|
5. Backup the metadata folder of all your nodes: `cd /var/lib/garage ; tar -acf meta-v0.6.tar.zst meta/`
|
|
6. Install Garage v0.7, edit the configuration if you plan to use OpenTelemetry or the Kubernetes integration
|
|
7. Turn on Garage v0.7
|
|
8. Do `garage repair --all-nodes --yes tables` and `garage repair --all-nodes --yes blocks`
|
|
9. Your upgraded cluster should be in a working state. Re-enable API and Web
|
|
access and check that everything went well.
|
|
10. Monitor your cluster in the next hours to see if it works well under your production load, report any issue.
