ODROID C2 ::: Resizing the microSD card issue

Postby dunghnguyen » 13 Aug 2016, 13:40

Hi Frank @hondagx35 ! Sorry to disturb but it seems we have only you who could help. I followed the instruction from Rune audio web to resize the microSD 16GB card on C2 but it seems failed although the indication below ssh is fine. Your support is highly appreciated. Thanks.

root@runeaudio(ro):~# set_rw

The filesystem is already 524288 (4k) blocks long.  Nothing to do!

root@runeaudio(rw):~# fdisk /dev/mmcblk0

Hi dunghnguyen,

the partitioning on the ODROIDs is different as on the other systems.
It has only one partition.
The resizing procedure is the same.
- use fdisk to change the partition
Code: Select all
fdisk /dev/mmcblk0

- del partion one
- create new partition with max size
- reboot
- use resize2fs
Code: Select all
resize2fs /dev/mmcblk0p1

complete.

/dev/mmcblk0p1 15G 1.9G 12G 14% /

For me this looks like it didn't fail.

Yes Frank, thanks for your advice and confirmation. As what I learnt from that the commands seems ok but when copying files to it, I just copied up to 3 flac album then it notified full, could not copy more. Let me try again. Again tks and have a nice day there !

Tried again but failed to copy files into the extended card. I just copied 2-3 album it meant about less 2GB then WinSCP dropped connection when files copying. No idea why?

For Pi2, I could copy files upto 14.6GB for the microsd card 16GB.

Hi,

please post your output from "df -h" after you get the error.

Frank

edit:

Wait, you ask this for the ODROID-C2.
This image is read-only as you may know.
Modifications will be kept in memory until you reboot or shutdown.
ODROID-C2 has 2GB memory and this is the limit.

Solution:

1. make the image read-write

2. - do not extend the sc card partition, but make a second one.
- mount this partition read/write
- symlink this partition to /mnt/MPD/LocalStorage

If I am not wrong I shared above I did the same as your advice already.
Thanks to advise me how to do for the red highlighted line in your comments.

I quoted again the commands that I did.

Code: Select all
root@runeaudio(ro):~# set_rw
root@runeaudio(rw):~# resize2fs /dev/mmcblk0p1
resize2fs 1.42.13 (17-May-2015)
The filesystem is already 524288 (4k) blocks long.  Nothing to do!

Hi dunghnguyen,

Thanks to advise me how to do for the red highlighted line in your comments.

Modify /etc/fstab to make the new partition mount at boot
Code: Select all
nano /etc/fstab

then add the following line
Code: Select all
/dev/mmcblk0p2  /mnt/MPD/LocalStorage ext2       noatime,rw          0       0

reboot
