Android를 이래 저래 수정을해서 사용을 해서 문제가 많네요...

저희가 NAND에 UBIFS를 올려서 Rootfs로 사용을 하고 있는데...

(TI OMAP3 비스무리한 AM3715 사용중, 256MB NAND, "df"해보면 약 15MB정도 Free space)

이 놈이 어떤 상황에서 Read-Only로 Mount가 됩니다.

원인은 아래처럼 ubifs_leb_unmap: unmap LEB -1 failed, error -22  인 것 같은데...

혹시 이러한 현상이 어떨 때 주로 일어나는지...

혹시 비슷한 현상을 경험해 보신 분이 계신지.....

혹시 File의 개수가 넘 많아졌을때 일어날 수도 있는지,

Free space가 적은 상황에서 전체 rootfs를 Update할 대 일어날 수 인는 건지..

DB File을 Write하는 중에 Power Off/On이 발생해서 일어날 수도 있는지.....

밖엔 눈이 오네요.... 일찍들 퇴근하세요.....
