MISCONF Redis is configured to save RDB snapshots
redis
Solution
In case you encounter the error and some important data cannot be discarded on the running redis instance (problems with permissions for the `rdb` file or its directory incorrectly, or running out of disk space), you can always redirect the `rdb` file to be written somewhere else.
Using `redis-cli`, you can do something like this:
CONFIG SET dir /tmp/some/directory/other/than/var
CONFIG SET dbfilename temp.rdb
After this, you might want to execute a `BGSAVE` command to make sure that the data will be written to the `rdb` file. Make sure that when you execute `INFO persistence`, `bgsave_in_progress` is already `0` and `rdb_last_bgsave_status` is `ok`. After that, you can now start backing up the generated `rdb` file somewhere safe.
Obviously, you should also have the dbfilename and dir changes reflected on the actual config file that you're using afterwards.
Problem
During writes to Redis ( `SET foo bar` ) I am getting the following error: MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error. Basically I understand that the problem is that redis is not able to save data on the disk, but have no idea how to get rid of the problem. Also the following question has the same problem, it is abandoned long time ago with no answers and most probably no attempts to solve the problem.
