RAMdisk enables using RAM as a block device for storage, supporting RAID configurations and requiring the Storage package. It is cleared on reboot or power loss, with a configurable size via ramdisk-size property.

Ramdisk

信息

This feature requires the Storage package. RAMdisk allows using part of RAM as an attached device (block device). Compared to tmpfs, this allows using RAM as part of a RAID, or in any other configuration where a device — rather than a folder — is required.

警告

A RAMdisk is cleared on reboot or power loss.

Properties

Configuration example

/disk/add type=ramdisk ramdisk-size=500M
