Don't paste pictures please. Not readable.

```

It sounds like you have a disk corruption or something like this?  
May be your system logs will tell you something?

As I said "disk corruption" ?

If you have a multi nodes cluster with replicas = 1, there are multiple options like switching off the node, fix the hardware problem (like a disk analysis) and restart the node.

What do you have?
