but that isn't the    real problem.  The real problem is that the volume header contains a    single piece of info, the data zone offset relative to the base of the    hammer filesystem, and it's a bit non-trivial to 'guess' it.                                                -Matt

I've regularly run hammer on a 20gb disk and currently on a pair of 40's; my snapshot retention time is set to 3600 days; no explosions yet. Just as long as you keep an eye on strikethe rearview mirror/strike df -h and reblock regularly, you'll be fine. Even if your hammer fills up, you can

Hi, A quick (I hope!) question re: HAMMER. I've obviously read that it's intended for a minimum filesystem size of 50GB, but if I wanted to try it out on a smaller size what sort of problems am I likely to see? Cheers, Steve -- SDF Public Access UNIX System - est. 1987 ==

New catastrophic HAMMER filesystem recovery tool in HEAD

2010-08-17 Thread Matthew Dillon
I've made a good first attempt at writing a HAMMER filesystem recovery directive to the hammer utility. It is now in HEAD. It works on the filesystem image (similar to the 'show' directive): hammer -f device recover empty_target_dir This is not a fsck. The filesystem
