[issue1984] hammer mount fails after crash - HAMMER: FIFO record bad head signature ..

["Thomas Nikolajsen \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

Thomas Nikolajsen <thomas.nikolajsen@mail.dk> added the comment:

The file system is 20GB.

I know this is rather small for a HAMMER FS.
It is just a root file system, for a x86_64 setup,
had to 'steal' from swap partition (still have 12GB for 8 GB mem)
it is not full at all.
Disklabel was already setup with i386 DragonFly system;
btw setting up dual boot i386/x86_64 works out quite easily w/ dloader ;-)

show-undo output is put on leaf:

Using supplied patch file system mounts R/W;
initially i mounted from i386 DragonFly, it seems fine.

After that I installed kernel w/ patch on x86_64 system,
it also mounted FS (now as root);
but after running for a few seconds it started giving errors;
the hammer_del_buffers message seemed endless; I had to power cycle.

I have no immediate plans to reformat FS; so if you have more ideas
on how to fix this I am all ears.
