[BPI-R3] OpenWRT 23.05.0 How to extend "production" partition?

I searched the previous discussions but could not find a solution to this specific use case. If not, please excuse me.

I just installed OpenWRT stable release and I want to extend Disk Space to have more room for packages. I run “parted” from EMMC and have this partitions:


Number  Start   End     Size    File system  Name          Flags
128     17.4kB  4194kB  4177kB                             bios_grub
 1      4194kB  4719kB  524kB                ubootenv      hidden, legacy_boot
 2      4719kB  6816kB  2097kB               factory       hidden
 3      6816kB  11.0MB  4194kB               fip           boot, hidden, esp
        11.0MB  12.6MB  1573kB  Free Space
 4      12.6MB  46.1MB  33.6MB               recovery      boot, hidden, esp
        46.1MB  67.1MB  21.0MB  Free Space
 5      67.1MB  176MB   109MB                production
 6      176MB   7818MB  7642MB               owrt-volumes  lvm

On Snapshot I used to reboot from NAND and then extend with parted using unallocated free space after the “production” partition. But on Stable release the free space after “production” partitions it is allocated as “owrt-volumes” (/dev/mmcblk0p6)

Can I delete the owrt-volumes before extend “production” (/dev/mmcblk0p5)? There is a different/better way to proceed?

Thanks

No,this will break system

And it is a lvm so you can add/resize partitions with lvm tools

Thanks! I will give a look to this tool.

Here are my notes for setting up each of my BPI-R3 boxes. This has been in stable use for many months now. This should solve your issue.

Getting OpenWRT onto the device in the first place: [OpenWrt Wiki] Sinovoip BananaPi BPi R3 V1.0, V1.1. Firstly put the sdcard image onto the sdcard, set DIP switches to boot into sdcard. Use the serial bootloader menu to have it write to NAND. Remove sdcard, set DIP switches to boot into NAND. Use the serial bootloader menu to have it write into eMMC. Set DIP switches to eMMC, it’s 8Gb of storage.

DIP switches:

  • 0000 NOR
  • 1010 NAND
  • 0100 eMMC (disables sdcard)
  • 1111 sdcard (disables eMMC)

BEFORE doing anything else you need to expand packages storage from its paltry 58Mb. I couldn’t get extroot working on these boards, so flip boot DIP switches to 1010 (NAND) and do:

opkg update
opkg install parted
parted /dev/mmcblk0
print
resizepart 5 +1G
reboot
mount /dev/mmcblk0p66 /mnt
umount /dev/mmcblk0p66
resize.f2fs -s /dev/mmcblk0p66
poweroff

Put DIP switches to 0100 (eMMC) and packages storage should now be 1Gb, which is more than plenty. Probably best to run firstinstall first to factory reset everything, then install autopart and uvol to have the system create a separate LVM partition in the remaining 6Gb of space, this can be formatted as f2fs and used as long term storage e.g. sensor readings. Configuring it as a samba share is useful.

Thanks for the procedure. I will give it a try.
