Describe the bug 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.
Expected behavior Redis can restore normal write operations
Comment From: sundb
@CCTV-six can you give the output of INFO ALL.
did you check if the rdb or aof can be saved successfully?
Comment From: raminrahimzada
Hi, I have encountered the save error:
MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error
This is the server_log fragment:
