After running the query below, server space is getting full in all data nodes ( ELK cluster: 3 masters, 3 data, 1 kibana node).

POST /apic\_sandbox/\_delete\_by\_query?wait\_for\_completion=false //change index here accordingly  
{  
"query": {  
"bool": {  
"must": [  
{  
"match\_phrase": {  
"catalog\_name": "sandbox" //change catalog name accordingly  
}  
}  
],  
"filter": [  
{  
"range": {  
"@timestamp": {  
"gte": "2022-07-15T18:00:00+05:30", //change the timestamp for which you need to delete  
"lt": "2022-07-15T19:00:00+05:30"  
}  
}  
}  
]  
}  
kindly help!

I don't think that the query cause the problem.

There is a useful command for top 10 largest directories:  
`du -h / | sort -rh | head -10`  
In few iterations, for instance 1. du -h /var 2. du -h /var/logs will lead you what to clean.

If you don't need, remove/move old ES logs, then if is possible clean /tmp directory, then other unused directories. Be aware, if you delete for instance 100 MB data will have immediately -100 MB on the disk and Lucene has own internal mechanism for releasing free disk space.

Thanks! @Rios for reply

I think issues are with tasks or processes which are not releasing disk. These processes start to resume when I start service.  
After adding another disk to the cluster it starts consuming that disk space also.

You have multiple disks on a node?
