when login to master pod & check

[elasticsearch@elasticsearch-master-1 ~]$ ls /data/ -ld
drwxrwsr-x. 5 root elasticsearch 4096 Mar 24 21:18 /data/
[elasticsearch@elasticsearch-master-1 ~]$ ls /data/log -ld
drwxrwsr-x. 2 elasticsearch elasticsearch 4096 Mar 24 21:18 /data/log

Input/output error

This means the operating system returned EIO from some kind of IO operation, which indicates a fundamental problem in your storage. You've deleted the bit of the stack trace that says what operation failed, but that's not normally very important anyway. Maybe check dmesg to see if there are any kernel logs indicating storage problems.
