The calculated node size\_in\_bytes value is very different from the actual df value  
I use "size\_in\_bytes" to check the usage of 2.6tb

The usage of du is 3.7 TB  
What's extra? It will be released when it reboots

Okay, let me correct my description  
"roles": [ -  
"data",  
"ingest",  
"ml",  
"remote\_cluster\_client"  
],  
"attributes": { -  
"ml.machine\_memory": "269942247424",  
"ml.max\_open\_jobs": "512",  
"xpack.installed": "true",  
"ml.max\_jvm\_size": "32212254720",  
"transform.node": "false"  
},  
"indices": { -  
"docs": { -  
"count": 223613139,  
"deleted": 61494359  
},  
"shard\_stats": { -  
"total\_count": 40  
},  
"store": { -  
"size": "2.1tb",  
"size\_in\_bytes": 2383964133115,  
"total\_data\_set\_size": "2.1tb",  
"total\_data\_set\_size\_in\_bytes": 2383964133115,  
"reserved": "0b",  
"reserved\_in\_bytes": 0  
}  
But from the perspective of the operating system, the actual occupancy is much larger  
du -sh \*  
8.2M config  
3.7T data  
4.0K es.pid  
2.8G logs  
4.0K version
