I may have run into some kind of a bug and looking for help.

I shutdown my machine and fired up a live usb, done some backups. I did
'dd if=/dev/windows_partition of=/dev/ext4_fs' and while this file had
been written the filesystem got filled 100%. Because this step took so
long I told my machine to shutdown automatically in about 2 hours and
went to bed.

Next morning I fired up my machine (Gentoo btw.) and opened irssi. All
was as usual, except of some weir behavior, because there was no space
left. I didn't recognize this from the beginning and so closed irrsi again.
I started irssi again and my config was lost. I found the config file in
the irssi dir with 0 bytes. :(

So, fill the drive, open a file, close the file and open it again leads
to loosing the file?

This is reproducable on this machine. Any help would be appreciated.
