It tried to run the application with changed parameters again.
It failed with a hammer error message (...panic...) and a debugger.
I did enter "reset", since I didn't find a quit/exit command.
After restart I do get error messages like:
no B_DEVMAGIC (bootdev=0)
Mounting root from hammer:serno/F34924R03250.s1d

HAMMER(ROOT) recovery failure during seqno backscan
HAMMER(ROOT) recovery complete
Failed to recover HAMMER filesystem on mount
Root mount failed: 5

So is there a way to recover this somehow or is it easier to just do a
fresh install?
I haven't seen this particular error myself. Several years ago I had an
issue with a too small UNDO log, but this was fixed.
You can always mount a HAMMER filesystem as read-only. In this case,
I guess, it should not trigger the UNDO TAIL signature panic. Once you
have the filesystem readonly, you can back it up, and later restore it
to a new HAMMER filesystem.

If you're using hammer, rm file isn't deleting anything from your

But aside from the fact rm isn't deleting anything, I think there is a
bug in ENOSPC handling.
I've once saw kernel panic soon after hitting ENOSPC.

Hello,
I do have a small problem, I've written a program that filled all
available
disk space (I know not very smart...).
Well now I have a few SQLite database files that I can't get rid of.
When executing "rm *" or just calling "rm a.9.db" for a single file
I do get
the error message "rm: a.9.db: No space left on device".
I suspect there is some space required to undo the delete which might
require extra space.
"hammer cleanup" or hammer prune[-everything] will help.

Michael
