Yesterday I installed a couple of games into my 770. And one of the
games didn't fit--I've filled up the partition. Scary things started
happening--the user interface became very nonresponsive, I couldn't
switch between tasks, I couldn't open the task menu, I couldn't tap on
the globe icon. I could switch to the desktop, but it wouldn't even
display my wallpaper--instead I got a white background and a dialog
saying "memory full, free some memory".
I had File Manager open. I could finally switch to it somehow. I tried
to delete something, and got an error ("Unable to complete operation").
Uh oh.
Finally I noticed that the user interface was becoming responsive again.
I could go online and ssh into my 770. I still could not delete any
files:
$ rm filename
rm: filename: No space left on device
dmesg was full of kernel messages about the JFFS2 garbage collector
being unable to find any free space. Uh oh.
I made backups and prepared for reflashing.
I rebooted. Opened up xterm, tried to delete a file. I could do it!
Then df showed me I had 11 megs freespace. The garbage collector must
have worked better after a fresh boot.
Moral:
* don't fill up your flash, or you'll be sorry
* I need more disk space, as usual
* the user interface was unresponsive because the 770 was very busy
writing to flash (or running the garbage collector), not because it
was out of disk space
I reflashed anyway, since it was way past time for me to upgrade to OS 2006.2.
I've written up a page with instructions for myself to make the
backup/restore less painful after a reflash:

The most interesting bit is probably the single-click install file for
OpenSSH. Although you do need to set the application manager into
red-pill mode to use it.
