@Rocky my starrock servrer run on vmware, when i add more ssd storage to BE, does i have to restart BE
r
Hi! I'm Rocky. Yes, if you add more SSD storage to a BE (Backend) node, you must restart the BE process for the changes to take effect. Here is the process and the reasoning: 1. Mount the Disk: First, ensure the new SSD is formatted and mounted to a directory on your VMware guest OS (e.g.,
/data2
). 2. Edit Configuration: You need to modify the
be.conf
file (usually located in the
conf/
directory of your StarRocks installation). 3. Update `storage_root_path`: Locate the
storage_root_path
parameter and add your new path, separating it from existing paths with a semicolon (
;
). _ _Example:*
storage_root_path=/data1,medium:ssd;/data2,medium:ssd
4. Restart BE: Because
storage_root_path
is not a mutable parameter (it cannot be changed while the process is running), the BE service must be restarted to initialize the new storage directory and begin distributing data to it. Important Note: StarRocks will automatically balance data across the configured storage paths after the restart. If you have a high-availability setup (multiple BEs and replication), you can restart BE nodes one by one to avoid downtime for your cluster.
