How to expand the OS disk on the SD card on Maix-II ?

Open chayitw opened this issue 3 years ago • 2 comments

Hi All, 我使用目前的鏡像版本 "maixpy3-0.3.5_MaixII-Dock_20211216.img", 由於其根目錄僅有254.5M的大小, 所以參考底下這篇說明想試著擴增到2G: https://www.cnblogs.com/USTHzhanglu/p/15207336.html

   但也僅能擴增到381.8M, 雖然可以開機, 但並沒有成功完成擴增, 底下是操作過程紀錄,
   可以給一些建議嗎? 感謝。

新年快樂 -chayi

hi @junhuanchen , 謝謝, 這個問題我自己解掉了, 剛看了一下您提供的連結, 發現很棒, 它考慮的更多、更詳盡, 如果有人單純是要做rootfs磁區擴增(分區擴容), 底下是我的方式以及一些紀錄, 也提供給社區成員參考看看。 謝謝, chayi

To expand the OS disk on the SD card on Maix-II

主要參考網址: https://www.cnblogs.com/USTHzhanglu/p/15207336.html

  1. 燒錄鏡像v831-m2dock-maixpy3-0.4.0-20220114.img到SD卡。

    (原本的磁區大小為) Device Start End Sectors Size Type /dev/mmcblk0p1 49152 49663 512 256K Microsoft basic data /dev/mmcblk0p2 49664 57855 8192 4M Microsoft basic data /dev/mmcblk0p3 57856 844287 786432 384M Microsoft basic data /dev/mmcblk0p4 844288 62333918 61489631 29.3G Microsoft basic data

  2. 取出SD卡到一般的UNIX系統，來擴充磁區大小: $sudo fdisk /dev/sdb

    (比如擴增成如下, p3在模組上由384M擴增為20G) Device Start End Sectors Size Type /dev/mmcblk0p1 49152 49663 512 256K Microsoft basic data /dev/mmcblk0p2 49664 57855 8192 4M Microsoft basic data /dev/mmcblk0p3 57856 42000383 41942528 20G Linux filesystem /dev/mmcblk0p4 42000384 62333918 20333535 9.7G Linux filesystem

    (預計在模組上會看到如下根目錄/變為19.9G) root@sipeed:/# df -h Filesystem Size Used Available Use% Mounted on /dev/root 19.9G 283.1M 19.6G 1% / tmpfs 29.4M 16.0K 29.4M 0% /tmp none 29.3M 0 29.3M 0% /dev /dev/mmcblk0p4 9.7G 24.0K 9.7G 0% /mnt/UDISK /dev/mmcblk0p4 9.7G 24.0K 9.7G 0% /root

    相關細節請見文末。

  3. 進行 e2fsck & resize2fs以讓FileSystem大小相符 $sudo umount /media/chayi/(rootfs) $sudo e2fsck -f /dev/sdb3 $sudo resize2fs /dev/sdb3

  4. 回到模組，開機成功且擴充完成。
