Partitioning is supported on ARM, ARM64, MIPS, TILE, and PowerPC RouterBOARD type devices.
It is possible to partition NAND flash, allowing to install own OS on each partition and specify primary and fallback partitions.
If a partition should fail for some reason (failed upgrade, problematic configuration introduced, software problem), the next partition will boot instead. This can be used as an interactive backup where you keep a verified working installation and upgrade only some secondary partition. If you upgrade your configuration, and it proves to be good, you can use the "save config" button to copy it over to other partitions.
Repartitioning of the NAND requires the latest bootloader version
Minimum partition sizes:
- 32MB on MIPS
- 40MB on PowerPC
- 48MB on TILE
The maximum number of allowed partitions is 8.
|repartition (integer)||Will reboot the router and reformat the NAND, leaving only active partition.|
|copy-to (<partition>)||Clone running OS with the config to specified partition. Previously stored data on the partition will be erased.|
|save-config-to (<partition>)||Clone running-config on a specified partition. Everything else is untouched.|
|restore-config-from (<partition>)||Copy config from specified partition to running partition|
|name (string; Default: )||Name of the partition|
|fallback-to (etherboot | next | <partition-name>; Default: next)||What to do if an active partition fails to boot:|
|active (yes | no)||Partition is active|
|running (yes | no)||Currently running partition|
|size (integer[MiB])||Partition size|
|version (string)||Current RouterOS version installed on the partition|
