Hi! If I mount a volume using RWX in Longhorn, share-manager builds the NFS share to the following path:

/dev/longhorn

Is there a way to change this path? I didn't find any arg in Helm chart vaules file (https://github.com/longhorn/charts/blob/master/charts/longhorn/values.yaml).

How did you bootstrap ( AKA the disk configuration ) of the nodes in your

Kubernetes

cluster that you wish to use for

persistent

storage needing workloads?

Because by e.g. setting the

create-default-disk=config

label on these nodes you can annotate those same nodes with

default-disks-config

and that

JSON

data can be used to configure the exact path on the nodes whereon the data should be stored … Making the path same no matter the type.

Of course you need to somehow bootstrap the path you specify in the

default-disks-config

JSON

data …

One tag related to the Longhorn component has been set on the storage nodes:

<http://node.longhorn.io/create-default-disk|node.longhorn.io/create-default-disk>: "true"

I installed the Longhorn component with the default settings. I didn't set any annotations e.g.

<http://node.longhorn.io/default-disks-config|node.longhorn.io/default-disks-config>

. Am I wrong in thinking that the

default-disks-config

parameter would be the same as the

defaultSettings.defaultDataPath

parameter? For example

Copy code

labels:
    <http://node.longhorn.io/create-default-disk|node.longhorn.io/create-default-disk>: "config"
},
annotations:
    <http://node.longhorn.io/default-disks-config|node.longhorn.io/default-disks-config>:    '[{"path":"/var/lib/longhorn","allowScheduling":false}]'

Hmm yes I think you are. The longhorn docs explains this pretty well.
