@<1523701157564780544:profile|TenseOstrich47> This is typically indicative of insufficient server disk space causing ES to go into read-only mode or turn active shards into inactive or unassigned (see FAQ ).

The disk watermarks controlling the ES free-disk constraints are defined by default as % of the disk space (so it might look to you like you still have plenty of space, but ES thinks otherwise). You can configure different ES settings in the docker-compose.yml file (see here - there are 3 settings, all can be identical)

If you don't have enough free disk space, clean up files to create more, or resize your partition (or increase your disk size if on a cloud instance).
