Re: [9fans] More venti sync woes.

["Anthony Sorace" <anothy@gmail.com>]

it's almost certainly venti sitting there; i don't think fossil is
even running yet. the last two lines on my screen are:

root is from (tcp, local)[local!#S/sdC0/fossil]: time...
venti...2007/0926 17:57:23 venti: conf...httpd tcp!127.1!8000...init...sync...

that sequence matches my read of the venti source. also, ^t^tp shows a
few venti procs that just keep racking up cpu time:

 8:     venti pc f0100366 dbgpc	2557f	Rendez (Running) ut 1547792 st
2058589 bss 6650000 qpc 0 nl 1 nd 0 lpc f01bb8ec pri 2
14:     venti pc   2557f dbgpc    2557f    Rendez (Ready) ut 2477463
st 2354871 bss 6650000 qpc 0 nl 0 nd 0 lpc f01c7bc7 pri 2
16:     venti pc f01c88ae dbgpc    1f141     Pread (Ready) ut 467438
st 1254296 bss 6650000 qpc f01c35e5 nl 0 nd 0 lpc f01bb8ec pri 1

they're definitely increasing more-or-less regularly. everything else
(well, i can't see above 8) had 0-2 for ut and st.

as for my venti config: i'll confirm when i get thin thing booted off
another medium, but from memory: i've got a ~30GB fossil partition, a
64MB bloom filter, a 5-10GB index, and a ~120GB arenas partition.
there's also a 9fat and swap in there somewhere. it's all on one disk.

i certainly appreciate the fact that non-dma disks can be dog slow
under load. but at this point, whatever it's doing it's been doing for
over 24 hours; even a factor of 50 puts that at just under half an
hour to reboot, which seems like an unreasonable amount of time for a
server to spin on an unclean reboot. what was the rough improvement
factor you observed?

this machine has no optical drive, so i'll have to make a floppy and
get it to boot of the net. i'll report back when i have info from
that.
