File empty after cutting of the power

[JonasR]

Hi,

i've got a problem, if I remove the power cord after writing a file and boot the plug again the file is empty. So I'm really sure its a problem with the filesystem(ubifs). I read that it caches the files before writing. So how can I force to write?

Thanks

Before pulling the power, use the "shutdown -h now" command from a shell and it will force a flush of the cache before halting.

From inside a program, I think fsync(handle) done before close(handle) does this.

Thanks for you reply.

The problem is that some customers wont type in the halt command for shutting it down :/
So I got to take the fsync method. Ill test how to handle this with perl and write it later in here
