Hi,
I am wondering if it is possible to create an always writeable distributed volume.
Reading the documentation I can figure out how. So is it possible?
If I understand the docs correctly. The DHT determines based on a hash of the filename, which brick to place the file. And if you have two bricks and loose one brick I can't create files DHT determines should be places on the failed brick.
I have tried creating a distributed volume on two bricks/nodes. And as the feared I can't write files DHT determines should be placed on a failed node. I am well aware and can accept that I can't access or re-create files already created on the failed node. But I would like to write new files.
Is there a setting/feature I can enable that allows me to create file on the available/online bricks even if DHT determines that the file should be placed on the unavailable/failed?
My use case is: I want to use a Gluster volume for temporary storage that is always available, as in I can always mount and write to it . We have a lot of media file that is transcoded on user request and there need at temporary storage for this operation. All I need is a temporary, fast and always accessible storage with no data security/replica.
Regards
Jesper
