Hi. To resize EMMC partition on a BPI R3 I used:
opkg update
opkg install parted
parted /dev/mmcblk0
print
resizepart 5 7G
reboot
mount /dev/mmcblk0p66 /mnt
umount /dev/mmcblk0p66
resize.f2fs -s /dev/mmcblk0p66
poweroff
But in OpenWrt 24.10 there’s no /dev/mmcblk0p66.
What is the proper way to resize EMMC partition on OpenWrt 24.10? Thanks
Ok. I’m going to answer myself.
Flash NAND → Flash EMMC → Start on NAND → cfdisk /dev/mmcblk0 → Resize /dev/mmcblk0p5
Start on EMMC and everything is ok.
This aproach I try without success. Everytime I get info “Cannoct do this on mounted FS”
You have to do it starting OpenWrt from NAND.
Thanks, I will try it. Thats a good point.
This was very usefull:
Flash NAND → Flash EMMC → Start on NAND → cfdisk /dev/mmcblk0 → Resize /dev/mmcblk0p5
On emmc I really see partition of 7.2GB:
mmcblk0 179:0 0 7.3G 0 disk
├─mmcblk0p1 179:1 0 4M 0 part
├─mmcblk0p2 179:2 0 512K 0 part
├─mmcblk0p3 179:3 0 2M 0 part
├─mmcblk0p4 179:4 0 4M 0 part
├─mmcblk0p5 179:5 0 32M 0 part
└─mmcblk0p6 179:6 0 7.2G 0 part
mmcblk0boot0 179:8 0 4M 1 disk
mmcblk0boot1 179:16 0 4M 1 disk
ubiblock0_4 254:0 0 16.3M 0 disk
fit0 259:0 0 10.8M 1 disk /rom
fitrw 259:1 0 7.2G 0 disk /overlay
But when I log to Luci, it still show 429MB.
df -h:
Filesystem Size Used Available Use% Mounted on
/dev/root 11.0M 11.0M 0 100% /rom
tmpfs 1.9G 288.0K 1.9G 0% /tmp
/dev/fitrw 429.7M 85.6M 344.1M 20% /overlay
overlayfs:/overlay 429.7M 85.6M 344.1M 20% /
tmpfs 512.0K 0 512.0K 0% /dev
What could be wrong ? Thank you.
I guess,you resized partition but not the filesystem
The first time I tried, the same thing happened to me on BPI-R3. And it was because participation /dev/mmcblk0p5 must be increased before openwrt has ever started on Emmc.
So should I make fresh install of openwrt from SD card? Flash to - nand and then to emmc and then resize partition on emmc from NAND? And then finally boot from emmc ?
Yes, that’s right the way I did It for BPI-R3. Rebember you’ll need cfdisk package on your OpenWrt image.
Ok, thank you a lot. I will install all needed package on NAND. I will try it and let you know about my result.
Hello, I try it all possible working scenario. I even try delete the partition “5” and create it again with cfdisk at NAND mode. After switch to eMMC I was and with “initramfs” recovery mode. I think resize openwrt over full flash eMMC is currently impossible. I found many question on openwrt forum withou solution. Maybe something will change when they release opnwrt 25… Thank you all for helping me.
Have you increased filesystem too? Not only partition…
