Does Redis crash from time to time?

Question

linux

Hello. About once a day, Redis crashes on a Linux server:

ERR Error running script (call to f_9bd406a64e43e31f0dde2849660e8cd56f340b85): @user_script:2: @user_script: 2: -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.

In the logs:

1468:M 28 Aug 11:49:40.126 # Background saving error
1468:M 28 Aug 11:49:46.044 * 10 changes in 300 seconds. Saving...
1468:M 28 Aug 11:49:46.047 * Background saving started by pid 13268
13268:C 28 Aug 11:49:46.047 # Failed opening .rdb for saving: Read-only file system

When trying to do `service redis-server restart` - hangs.
"kill -9 pid" helps to restore work

Answer 1

Not writeable to RDB.
Show ls -lh /var/redis/

Answer 2

# Failed opening .rdb for saving: Read-only file system

well?
Configured to write a copy of the data to disk. Can't write a copy. Radish takes offense and leaves for RO.
