In cases where a ScyllaDB node fails to start because there is improper ownership, the following steps will help.
Phenomena ^^^^^^^^^
ScyllaDB node fails to start.
In cases where the ScyllaDB node fails to start, check ScyllaDB :doc:logs </getting-started/logging/>. If you see the following error message:
Could not access <PATH>: Permission denied std::system_error (error system:13, Permission denied).
For example:
.. code-block:: shell
Jul 01 07:31:48 ip-172-16-12-198 scylla[12189]: [shard 0] init - Could not access /var/lib/scylla/commitlog: std::system_error (error system:13, Permission denied) Jul 01 07:31:48 ip-172-16-12-198 scylla[12189]: [shard 0] init - Could not access /var/lib/scylla/data: std::system_error (error system:13, Permission denied) Jul 01 07:31:48 ip-172-16-12-198 scylla[12189]: [shard 0] seastar - Exiting on unhandled exception: std::system_error (error system:13, Permission denied)
Problem ^^^^^^^
The data directories /var/lib/scylla/data and /var/lib/scylla/commitlog exist but are not owned by the ScyllaDB user.
For example:
.. code-block:: shell
[centos@ip-172-16-12-132 scylla]$ ls /var/lib/scylla/data total 4 drwxr-xr-x 2 root root 4096 Jun 18 09:37 commitlog drwxr-xr-x 7 root root 97 Jun 18 09:37 data
In this example, the user root is the owner of the directories.
Solution ^^^^^^^^
.. code-block:: shell
sudo chown scylla:scylla /var/lib/scylla/data
.. code-block:: shell
sudo chown scylla:scylla /var/lib/scylla/commitlog
.. code-block:: shell
[centos@ip-172-16-12-132 scylla]$ ls /var/lib/scylla/data total 4 drwxr-xr-x 2 scylla scylla 4096 Jun 18 09:37 commitlog drwxr-xr-x 7 scylla scylla 97 Jun 18 09:37 data
