HAMMER2 emergency space mode

As anyone who has been running HAMMER1 or HAMMER2 has noticed, snapshots and copy on write and infinite history can eat a lot of disk space, even if the actual file volume isn’t changing much.  There’s now an ‘emergency mode‘ for HAMMER2, where disk operations can happen even if there isn’t space for the normal history activity.  It’s dangerous, in that the normal protections against data loss if power is cut go away, and snapshots created while in this mode will be mangled.  So definitely don’t leave it on!

I’m leading with the most complex but perhaps also most unfulfilling link.

A mix of complaints, history, and odd technical items.  The usual!

I’m sure there’s some recent stuff I missed; I will catch it in next week’s roundup.
