Whose Error Is It?
Redis printed this
MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk.
What it meansRedis failed to write its background RDB snapshot to disk, so it now refuses write commands to avoid silently losing data.
The first thing to checkCheck the Redis log for the reason, usually a full disk or no write permission on the dir path; fix that, or set stop-writes-on-bgsave-error no.
