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

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! :smiley:
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 :slight_smile:

Thank you. I've revised it :咧嘴笑:
