We are currently using YugabyteDB stable version 2.20.5.0 and have started using `yugabyted`. We would like to know if `yugabyted` supports specifying multiple data disks using the `--data_dir` flag.

current: --data\_dir=/mnt01/data01

looking for: --data\_dir=/mnt01/data01, /mnt02/data02

Hi @parvez The version `2.20.5.0` doesn’t support multiple data disks. It was introduced in the [2024.1](https://docs.yugabyte.com/preview/releases/ybdb-releases/v2024.1/#yugabyted-5) release.

However, The database itself has support for multiple disks, its only yugabyted added support for it in 2024.1 release. I believe we can directly set the data\_dirs by setting the correct gflags when starting yugabyted.

Try something like:

`yugabyted start --tserver_flags="fs_data_dirs={/root/d1,/root/d2}"`
