When create index ,ela will create index catalog in all data path

[wangdwcsd]

my cluster has 10 nodes，every node has 24 disk ,
my cluster data path:

path.data:  /data1,/data2,/data3,/data4,/data5,/data6,/data7,/data8,/data9,/data10,/data11,/data12,/data13,/data14,/data15,/data16,/data17,/data18,/data19,/data20,/data21,/data22,/data23,/data24

[ela ~]$ for i in `find /data* -name TuiBZL2jRZyiDQZg0e0XuQ`; do du -sh $i; done

i create a index ，40 shares，I think 4 shares should be saved on each node, and each share will be saved in a different data path, but I see that 4 shares are put in the same data path

This way of data allocation leads to unbalanced use of different data path disks on the nodes

Can I improve this situation by modifying the ela configuration

Welcome!
Please don't post pictures of text, they are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them

Thank you. I've revised it :咧嘴笑:
