I changed the execution of this from 10 minutes to an hour. (to make it easier to scan the log)

Does anyone know that offl_chk actually does? Will bumping it from 10 minutes to an hour be a problem?

If I run "strings /usr/sbin/offl_chk", I get some text.
The best part (no compile info and such) is:

Code:

So what I think it does (and also what the name seems to indicate) is that this programs checks the online status of your drives.
So if for some reason the drives are set offline, this will try to set then online.

This also answers one question I had myself about umount my disks (I'm running ffp from usb stick) and doing a e2fsck on it.
