Re: [9fans] anyone put their venti on an SSD?
I had originally used a Crucial 32GB SSD years ago and swapped to a 55GB OCZ enterprise drive (using sdahci). More recently I've moved my venti arenas over to plan9port and have switched over to using the entire SSD for fossil. So far this has been faster than running venti natively - though I still take a replica each night out of paranoia.

cwfs copies the blocks from worm into the cache on read. so the working set is served from the ssd and the ram buffer cache. reading /n/dump would hit the mechanical disk tho. -- cinap

Re: [9fans] anyone use 9vx with root from kenfs?
The Plan 9 network stack and the work dho did was merged in my repo (and so in ron's and others) a long time ago. It was one of the first things I did. There are two options: to use a pcap-based ethernet device (which needs root) or a tun/tap one (then you don't need root, but will probably want to set up a virtual network). Though none of them are enabled by default, this can be changed using command line arguments or a plan9.ini file. Everything should be explained in the man page. -- - yiyus || JGL .

I did that just after 9vx was announced. /net was ported from plan9 by devon iirc. and il was easy to port then mod some sign issues. it depended on raw networking.

Re: [9fans] Anyone using p9p or Plan 9 venti as a more generic backup system?
I use vac -a to back up several unix systems to my main Plan 9 file server. Currently I'm doing two nightly via cron and two sporadically (laptops); there have been more of each in the past. In addition to storing the scores locally, I wrote a little rc script that lives in /rc/bin/service.auth and accepts scores and stores them on my CPU server. Combined with a simple 9fs addition, I can always 9fs foo.vac and get foo's history of archives from all my plan9 systems. I've also done restores from p9p, but have not exercised that well. I considered using vbackup instead of vac on the unix side, but it didn't look practical to get at the results from plan9. Also, I really needed to be selective in what I saad backing up (there's a few hundred Gb of post-processed video I don't need to store on one of these systems, and growing daily). This has worked very well for me overall; my only problem has been vtcache exhaustion on some backups, which I haven't been able to track down. Thankfully the error is on backup, not restore, so you know something's gone wrong when it happens. My message about vtcache is at http://9fans.net/archive/2010/02/307. I'm not sure I pushed the absolute latest to sources, but some version of my unix backup script is at /n/sources/contrib/anothy/bin/rc/vacbak.

I have a number of vac archives that were made by vac-ing my homedir that cannot be mounted (venti can't find some of the scores in the tree). However, they did pass scrubbing (scrub was a tool i wrote that is sorta like half of venti/copy -- it traverses a tree, checks hashes, but doesn't write them out to anything). I have a number of trees in which somehow the SHA1 of the empty string was inserted: 'da39a3ee...'. And I have a number of trees that were venti/copied from one venti to another but somehow damaged (scores missing) after the copy, without seeing errors. vac -a in particular was good at producing archives which either don't mount or are filled with missing scores or zero-scores vs sha1(empty string) problems. Unvac is not useful for anything involving directories, since it outputs dirs which cannot be modified. http://groups.google.com/group/plan9port-dev/browse_thread/thread/8b0e2bc4b45d12b0 is a reasonably common bug from vac, seen on deep-ish directory trees.
