我用nfs启动的文件系统,按照步骤
./flash_erase /dev/mtd3 0 0
./ubiattach -m 3
./ubimkvol /dev/ubi0 -N lvapp -s 500MiB

[root@FORLINX6410]# mount -t ubifs ubi0_0 /mnt/ubifs
mount: mounting ubi0_0 on /mnt/ubifs failed: Device or resource busy
最后总是提示 这个 挂载失败的错误.ubifs 这个目录是我刚建的,没人用的.

[root@FORLINX6410]# df -h

求教啊~~~实在不知道什么问题了~~~~

不知兄台这问题解决没,我也差不多遇到同类型的问题. 我执行 ubiattach 成功后. 去mount ubi, 老提示 no such device. # ln -s busybox mount # mount # ./mount -t ubifs -o sync ubi0_0 /mnt mount: mounting ubi0_0 on /mnt failed: No such device
