Unable to change data directory in Scylladb. Scylla server failing on change of data directory

[praveenhello124@gmail.com]

I am trying to change data directory in scylla.yaml but after changing the scylla-server is not starting

[root@m1 vagrant]# sudo systemctl status scylla-server

The directory to which I am trying to change data directory is a shared folder for host machine and vagrant container.

Kindly help me in resolving this issue

Hello, can you provide full log from `sudo journalctl -u scylla-server`?

What's your scylla version?

If it's convenient, you can report scylla issues on github next time :-)

Scylla runs on XFS (recommended) and EXT4. The shared folder is probably with a filesystem which fails some of the tests in the scylla. Can you post the complete scylla-server log so we can see what is failing.

Another easy to use option which allows to collect many inputs on your server would be to use the node_health_check script.
Among another things it also collects system / server info, as well as Scylla info.
Here are instructions on how to use it and where to find it: https://github.com/scylladb/scylla/wiki/How-to-report-a-Scylla-problem

Scylla runs on XFS (recommended) and EXT4. The shared folder is probably with a filesystem which fails some of the tests in the scylla. Can you post the complete scylla-server log so we can see what is failing. 

 

Probably, the scylla user doesn't have permissions to create subdirectories in the new data directory.

Hi Avi Kivity/Tomer Sandler/Asias He/Amos Kong,

Thanks for the suggestion and sorry for the delayed reply.

As Avi told the data directory I am trying to change is not having permissions to create subdirectories. 

The issue is figured out finally
