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

```auto
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

```

```auto
[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

```auto
/dev/sdb 1.1T 127G 918G 13% /data1
/dev/sdc 1.1T 77M 1.1T 1% /data2
/dev/sdd 1.1T 152G 892G 15% /data3
/dev/sde 1.1T 157G 887G 16% /data4
/dev/sdf 1.1T 158G 886G 16% /data5
/dev/sdg 1.1T 157G 887G 16% /data6
/dev/sdh 1.1T 235G 809G 23% /data7
/dev/sdi 1.1T 157G 887G 16% /data8
/dev/sdj 1.1T 343G 701G 33% /data9

/dev/sdx 1.1T 77M 1.1T 1% /data23
/dev/sdy 1.1T 639G 405G 62% /data24

```

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 🙂
