cannot find primary, retrying: no primary

,

I’m trying to use litefs with a remix app deployed on fly.io. however, I’m stuck as the logs keep repeating this:

lax [info] level=INFO msg="cannot become primary, local node has no cluster ID and \"consul\" lease already initialized with cluster ID LFSC7EB2721C01B8BAFB"

lax [info] level=INFO msg="cannot find primary, retrying: no primary"

I inspected both of my machines but they are both replicas, and I can’t find a way to set it to primary.

Heres my litefs.yml:

fuse:
  dir: "${LITEFS_DIR}"

data:
  dir: "/data/litefs"

exit-on-error: false

proxy:
  addr: ":${INTERNAL_PORT}"
  target: "localhost:${PORT}"
  db: "${DATABASE_FILENAME}"

exec:
  - cmd: npx prisma migrate deploy
    if-candidate: true

  - cmd: sqlite3 $DATABASE_PATH "PRAGMA journal_mode = WAL;"
    if-candidate: true

  - cmd: "PORT=8080 npm start"

lease:
  type: "consul"
  advertise-url: "http://${HOSTNAME}.vm.${FLY_APP_NAME}.internal:20202"
  candidate: ${FLY_REGION == PRIMARY_REGION}
  promote: true

  consul:
    url: "${FLY_CONSUL_URL}"
    key: "litefs/${FLY_APP_NAME}"

and heres my Dockerfile:

heres fly.toml if it helps:

Hi… Try changing the final line to…

key: "litefs/${FLY_APP_NAME}-neo"

(Using that exact suffix isn’t critical, as long as it’s one that you’ve never initialized before.)

Hope this helps!
