d1s下的overlays挂载问题，提示“No such device”

[casojie]

D1S 无法挂载overlays，开机打印如下

在贴吧也搜索到类似的问题，都是修改base-file里的文件，但是我是使用的busybox-init, 都找不到对应的fstat文件，感觉分区设置好像有问题，太蔡了，求大哥指点，以下pack的log

overlayfs挂载失败是因为分区没有格式化，分区挂载失败，只读文件系统没法创建必要的文件夹，最终导致overlayfs挂载失败的吧

这个帖子里好像有挂载的方法
芒果d1h用sd卡烧录后创建文件夹一直Read-only file system

[casojie]

@suncw 我不是很明白，根目录下是有overlay文件夹的，它应该不需要创建文件夹了吧，而我也尝试手动挂载，也是提示

root@TinaLinux:/# mount -t ext4 -o sync,data=journal /dev/by-name/rootfs_data /o
verlay/
mount: mounting /dev/by-name/rootfs_data on /overlay/ failed: No such device

我也尝试执行

root@TinaLinux:/# mkfs.ext4 /dev/by-name/rootfs_data 
mke2fs 1.46.4 (18-Aug-2021)
/dev/by-name/rootfs_data contains a ext4 file system
	created on Thu Jan  1 08:07:28 1970
Proceed anyway? (y,N) y

仍然不行，唉

@casojie
overlayfs挂载除了overlay文件夹还要依赖其他文件夹，比如upper、workdir。光看根目录下是有overlay文件夹可能不行。。。。。。

帖子里提到的将根文件系统改为ext4格式和修改代码两种方式应该都可以正常挂载

或者您要是想手动格式的话，也可以在电脑上进行格式化，找u盘最后一个分区进行格式化
类似mkfs.ext4 /dev/sbd8

设备上格式化应该也可以，但是可能不能自动挂载，可能需要重启一下

[casojie]

@suncw 抱歉，我还是不明白，我的设备是emmc存储，mkfs.ext4 在板子上是可以正常使用的，看完后我还是不知道应该怎么做，而且我使用的是busybox-init 对应的以下fsata文件都没有

[TEVET]

@casojie
是使用了 rootfs_data 是否有这个 partition 呢
检查一下sys_partition.fex 吧，贴上来看看
报错提示你没有这个 /dev/by-name/rootfs_data ，极可能是 sys_partition.fex 没有这个分区信息。
你要自己加一下 ，如下，size 可以自己改

[partition]
name = rootfs_data
size = 25600
user_type = 0x8000

[casojie]

@tevet 前几天解决了，谢谢回复

[kjlsai]

@casojie 请问是怎么解决的
