RancherOS will store its state in a single partition specified by the dev
field. The field can be a device such as /dev/sda1
or a logical name such LABEL=state
or UUID=123124
. The default value is LABEL=RANCHER_STATE
. The file system type of that partition can be set to auto
or a specific file system type such as ext4
.
#cloud-config
rancher:
state:
fstype: auto
dev: LABEL=RANCHER_STATE
You can specify a list of devices to check to format on boot. If the state partition is already found, RancherOS will not try to auto format a partition. By default, auto-formatting is off.
RancherOS will autoformat the partition to ext4
(not what is set in fstype
) if the device specified in autoformat
:
rancher.state.formatzero
is true#cloud-config
rancher:
state:
autoformat:
- /dev/sda
- /dev/vda
