Can the /var/discourse and /var/docker folders be on different volumes?

I’m self hosting on Linode and am planning to add a block storage volume because there’s no longer enough space for Discourse to compress its backups. (I’ve done a docker image prune etc which is giving us a bit of time, but we’ll need to upgrade the server soon.)

Do the /var/discourse and /var/docker folders need to be on the same volume, or could one stay on the original server’s disk and the other move to the new block storage volume? I suspect that Linode block storage volumes are stored very close to the shared CPU drives (possibly sometimes even on the same physical drive).

Does anyone have any experience with adding a block storage volume on Linode, and whether it would hurt performance to put these folders on different volumes?

/var/discourse is just the docker manager, no? That can be anywhere, I typically just leave it in /root because it doesn’t matter and doesn’t really store data, even if “best practice” is /var/discourse.

For /var/docker, I haven’t personally had experience doing so, but there should not really be any impact so long as you properly mount it. I’m not sure how things work on the cloud side but typically this is a very easy 5 minute task to mount a disk to a specific partition.
