Many file servers using disk drives are "unreliable" if you shut them down
without saving data in memory first.
Both /sys/src/fs and disk/kfs force certain metadata updates to disk first
to try to ensure that the fs structure,
if not the content, remains consistent. In fact, disk/kfs does more than

Thanks for the explanation.

Make sure you're not confusing kfs with Ken's
You can use kfs or cwfs with venti but the usual combination is
venti with fossil, this is more of a symbiotic arrangmenet than
venti would be with the others. Cwfs contains an archival server
and a short term store like venti and fossil.
mirroring and striping is possible with cwfs's backend, or
I want to build a Plan9 storage server for home, so I figured this
thread might be a good place to ask. I know nothing about what
hardware to buy.
I want to use venti for permanent storage. For temporary storage that
might or might not be saved to venti, I don't know, I've been thinking
of cwfs.
Hello,
Perhaps somebody will have hints about the following.
I work with ou for small to middle sized enterprises, that can have the
need for a GIS infrastructure.
The data is the crux; but the evolution of data, and the ability to be
