Why we do NFS fileserving with a SAN
Our storage infrastructure here has a number of NFS servers sittingin front of a pool of SAN RAID storage boxes using commodity SATAdisks. This is a somewhat unusual setup for a comparatively smallenvironment like ours; a far more common setup is to have the disksdirectly attached to the fileservers.
We have a SAN setup for a simple reason: failover between the NFSserver machines . We consider the server machines to be the things mostlikely to suffer failures, either hardware or software, or just to needdowntime. With

Programming fun
Programming fun is spending a couple of hours writing, revising, andtuning a DWiki feature that I'm not sure I'm actually going to like wellenough to keep.
I'm serious, not being sarcastic; I like programming, but not all ideasfor improving a program pan out. An idea that seems great in my mind canbe less attractive once I've made it concrete and explored all of thebits that I could gloss over when it was just thought-stuff. So I can

If you plug your keyboard into the back USB connectors, the Ubuntu6.06.1 x86_64 server kernel hangs with ' BUG: soft lockup detectedon CPU#0!

Something all full-service backup systems should have
Having spent much of today wrestling with this very question, I have asmall suggestion for people designing full-service backup systems (bywhich I mean ones that have individual file indexes and an environmentfor restoring single files):
Please provide a command that summarizes all of the versions ofa file that you know about.
Most full-service backup systems can go back in time, so you can ask forthings like 'the version of the file on January 28th'. But what I reallywant is
