I don't know; attempts to restore my system have so far been failures, resulting in a host of error messages yet failing to repopulate the filesystem. :-(
I have recovered my filesystem by reformating the fossil writebuffer with the contents of the last venti snapshot. (This may be a rather drastic measure, though.) Just for convenience, here's what I did: (I have a standalone Plan 9 machine with a venti and fossil partition on sdC0.) Boot Plan 9 from a recent installation CD and enter the following commands in a rio window: # configure ip address and set venti environment variable ip/ipconfig ether /net/ether0 192.168.1.2 255.255.255.0 venti='tcp!192.168.1.2!venti' # save the venti config to a file, because venti needs it to start venti/conf /dev/sdC0/arenas > /tmp/venti.conf # then start venti venti/venti -w -c /tmp/venti.conf -a $venti # start fossil fossil/fossil -f /dev/sdC0/fossil -c 'srv -p fscons' # determine the score of the last archival snapshot fossil/last /dev/sdC0/fossil vac:a92cc4d2657044cfaadf3d4c9dbce3e89932c35a # now format the writebuffer fossil/flfmt -v a92cc...c35a /dev/sdC0/fossil # log in the fossil console and halt fossil con -l /srv/fscons fsys main sync fsys main halt Cheers Christian
