Common Parameters

These are the most common parameters which apply to all components of Vitastor.

• config_path
• etcd_address
• etcd_prefix
• log_level

config_path

• Type: string
• Default: /etc/vitastor/vitastor.conf

Path to the JSON configuration file. Configuration file is optional, a non-existing configuration file does not prevent Vitastor from running if required parameters are specified.

etcd_address

• Type: string or array of strings
• Can be changed online: yes

etcd connection endpoint(s). Multiple endpoints may be delimited by "," or specified in a JSON array ["10.0.115.10:2379/v3","10.0.115.11:2379/v3"]. Note that https is not supported for etcd connections yet.

etcd connection endpoints can be changed online by updating global configuration in etcd itself - this allows to switch the cluster to new etcd addresses without downtime.

etcd_prefix

• Type: string
• Default: /vitastor

Prefix for all keys in etcd used by Vitastor. You can change prefix and, for example, use a single etcd cluster for multiple Vitastor clusters.

log_level

• Type: integer
• Default: 0
• Can be changed online: yes

Log level. Raise if you want more verbose output.
