Configure etcd storage quota

You can control the etcd distributed key-value storage quota using the etcd.storageQuota parameter in the mke4.yaml configuration file. By default, the value of the parameter is 2GB.

If you choose to increase the etcd quota, be aware that this quota has a limit and such action should be used in conjunction with other strategies, such as decreasing events TTL to ensure that the etcd database does not run out of space.

Warning

If a manager node virtual machine runs out of disk space, or if all of its system memory is depleted, etcd can cause the MKE 4k cluster to move into an irrecoverable state. To prevent this from happening, configure the disk space and the memory of the manager node VMs to levels that are well in excess of the set etcd storage quota.
