How do I configure using custom pvc as data storage?
How do I configure using custom pvc as data storage? Can you give an example?
Hello!
By custom PVC - do you mean manually created PVC Objects?
Best, Adam.
Yes, I am using juicefs to do storage and calculation separation for arangodb on k8s; therefore, I do not want to use local storage; I manually created a pvc. I would like to know how to configure the arangodb cluster on k8s to use the pvc I created by myself as data storage. @ajanikow
Hello!
Which mode is interesting for you - Single/Cluster?
And which versions of ArangoDB/Operator do you use? CE or EE?
Best Regards, Adam.
I want to do this on cluster mode and I'm using the CE version，Looking forward to your reply @ajanikow
Hello!
For cluster mode in CE, it will be tricky.
In EE we can change member indexing, which will enable us to use predictable member names.
For CE you need to prepare your own ArangoDeployment Status, like described here: https://arangodb.github.io/kube-arangodb/docs/how-to/recovery.html#initial-arangodeployment

I mean that I have a pvc containing a database file, and I just want to change the database path to access the pvc in cluster mode, like setting the --database.directory parameter. Can this operation be implemented? @ajanikow
Hello!
No, the above example shows you how to tell ArangoDB to use your PVC instead of a new one - you cant mount 2 data PVCs, the data format in the PVC needs to be ArangoDB-compatible and it always needs to be under /data
Best Regards, Adam.
I want to store the data on another node instead of using local storage. Is it possible to do so according to the sample document you gave? @ajanikow

You can use PVC definition, the document just shows you how to create it for LocalStorage, but you can create PVC on your own (store it anywhere you want, just PV and PVC need to be valid)
