Issue on Adding Node for ScyllaDB
May 14, 2021
- if you have problem when adding new node for cluster on docker,
“Could not setup Async I/O: Resource temporarily unavailable. The most common cause is not enough request capacity in /proc/sys/fs/aio-max-nr” - try to check “cat /proc/sys/fs/aio-max-nr” => 65536
- To solve the problem, you have to add the below line to your file /etc/sysctl.conf .
“fs.aio-max-nr = 1048576” - After you have done, you can activate your settings by executing the following command: “sysctl -p /etc/sysctl.conf”
