[KUDU] Adding tablet server data directories
Hi,
Need help again)
I've added "Kudu tablet server data directories" and kudu doesn't start:
...
FSManager root is not empty <path to old data directory>.
...
How to keep my old data and extend directories list? (I can't use LVM)
Looking forward to any answer, thank you in advance,
Best regards,

Hi Andrey,
Currently, servers require that the data directories do not change. Your best bet right now would be to write your data elsewhere first (e.g. to parquet files), shut down your server, wipe the current data directories, restart the server with all desired directories, and reinsert your data.
Disk configuration is a known pain point for Kudu; there is a JIRA open for this, found here<https://issues.apache.org/jira/browse/KUDU-2062>.
Hope this helped,
Andrew
