Installing alternate firmware to a My Cloud is generally NOT supported. Most times there are problems and issues, particularly with the single bay/single drive My Cloud models when attempting to install alternate firmware due to the unit’s limited/low power hardware and limited RAM. If you haven’t done so already use the forum search feature (magnifying glass icon top right) to search for the past discussions on using OMV on a My Cloud. Most have trouble getting any sort of alternate firmware to run on the My Cloud and usually end up with somewhat crippled alternate firmware if they are partially successful. See the following for the main discussion topic on alternate firmware:
Clean OS (Debian), OpenMediaVault and other “firmwares”
Word of note. The My Cloud Home device is not the same as a My Cloud device. The My Cloud Home uses a different operating system and has different hardware than the My Cloud line of devices.
