[root@db ~]# tiup cluster check topology.yaml --apply --user root [-p] [-i /home/root/.ssh/gcp_rsa]
Starting component cluster: /root/.tiup/components/cluster/v1.8.2/tiup-cluster check topology.yaml --apply --user root [-p] [-i /home/root/.ssh/gcp_rsa]
Perform preflight checks for the cluster. By default, it checks deploy servers
before a cluster is deployed, the input is the topology.yaml for the cluster.
If ‘–cluster’ is set, it will perform checks for an existing cluster, the input
is the cluster name. Some checks are ignore in this mode, such as port and dir
conflict checks with other clusters
Usage:
tiup cluster check <topology.yml | cluster-name> [flags]
Flags:
–api-timeout uint Timeout in seconds when querying PD APIs. (default 10)
–apply Try to fix failed checks
–cluster Check existing cluster, the input is a cluster name.
–enable-cpu Enable CPU thread count check
–enable-disk Enable disk IO (fio) check
–enable-mem Enable memory size check
