I have an IDE HD with fossil (no venti) partition on it. It contains some data precious to me. I would like to mount it on a native Plan9; yes, I've RTFM, but it seems to me too brief for me to avoid (fatal) mistakes. Thus, could some nice person lead me step - by - step?

Let's say your disk is named sdE1 and have a Plan 9 partition named "fossil". % fossil/fossil -m 20 -f /dev/sdE1/fossil -c 'srv -AWPV fossil.other' -c 'srv -p fscons.other' Then, you can mount it: % mount /srv/fossil.other /n/fossil And to halt it: % echo fsys all sync >>/srv/fscons.other % echo fsys all halt >>/srv/fscons.other -- David du Colombier ^ permalink raw reply [flat|nested] 6+ messages in thread

David's already provided good instructions on dealing with your immediate problem, but allow me to take a step back: Don't do that! Fossil, without venti, is not the stablest thing around. I would very strongly recommend against putting precious data on it. I've had it go wonky personally, and there've been plenty of similar reports here. In my experience, it's particularly vulnerable to unclean shutdown, but I've seen more difficult-to-explain issues, too. With venti, it's great: the snapshotting capabilties are very nice, venti's very solid, and if your fossil does get out of whack, it's trivial to re-initialize it from a known-good state from venti.

However, I reorganize my data very often, moving between dirs, renaming, reorganising tree structure... How will Venti cope with this? Fopr now, I plan to put the data onto an ext2 partition for now, until I feel the dir tree is well-designed. I just want to mount the fossil partition and copy the data out of there.

Well. Venti does block-level deduplication. If you have 100 MB of data in dir A and move it to dir B, you're not going to duplicate that storage (you'll get new blocks for the directory, of course, but that's both minimal and unavoidable).

I must first decide on a (quasi)stable dir tree. The problem is that I have almost 2TB of data, so should I have another 2TB disk for Venti if I want to put there all? Thanks, Peter.
