More colo box setup

On the new box:

  • Boot it up
  • Shut down all three domUs with “xm shutdown”
  • Mount all three domU disks in /mnt/xen[1-3]

On the old box:

  • Set up an authorized key so that root on the new box can ssh into root on the old box
  • Make a snapshot of one of the disks with lvcreate -L 100G -s -n xen1-snapshot /dev/xen-space/xen1-disk
  • Mount it with mount /dev/xen-space/xen1-snapshot /mnt/xen1

On the new box:

  • Copy the changed files using rsync -aSuvrx --numeric-ids --delete -e ssh --exclude /lib/modules root@xen.xcski.com:/mnt/xen1/ /mnt/xen1

On the old box:

  • Unmount the snapshot
  • Remove the snapshot with lvremove /dev/xen-space/xen1-snapshot

What have I been up to recently?

Since the Tupper Lake race, I’ve only paddled the ski. I need to get used to paddling in waves, with the Rochester Open Water Challenge less than two weeks away. Tonight, for instance, Paul D and I did some surfing, but we also spent some time paddling up and down the shore – our theory was that we would experience waves from the side, which is the hardest to handle, but we were in shallow water so if we dumped (and I dumped a few times) it was no trouble to get back in the boat. I haven’t been paddling with my GPS much, so I don’t know what has happened to my training volume other than the feeling that it’s way down. Paddling out in the surf requires different muscles and it’s not particularly fast, so an hour or an hour and a half is about all I can stand, and I probably make less than 3 or 4 miles in that time.

I’ve also settled on a name for the ski. In the past, I named my Skerray “Mary Ellen Carter”, after the song by Stan Rogers, because it enabled me to “rise again”, and the Looksha was “Gideon Brown” after the song by Great Big Sea, because she can “punch ahead in any gale”. I called the Thunderbold “Anne-Marie” after the boat in Stan Rogers’ song “Acadian Saturday Night” because it has “wings on the water”. And so now I’m naming the ski Old Polina because I “fly a long like a song” in it. Or at least I hope to.

I had a great visit with my dad, step mother and kids this weekend. It’s great to see them, especially my daughters. They’re both maturing so well. I still worry about them, but I suppose that’s my job.

In other news, I’m still trying to finish setting up the replacement hardware. I’m experimenting with using LVM snapshots to be able to backup the domU partitions while they’re active – I think what I’ll do is make snapshots, rsync them over to the new server’s partitions, then delete them, and then shut down the domUs and rsync them again while they’re shut down, and then start up the new guys. By rsyncing once with snapshots, that should make the amount of time between shutting down the partitions and bringing up the new ones much faster. I’m also going to look into replacing my current rsync backup scripts to ones that use snapshots as well, because that way I never have to worry about inconsistencies in the file system, especially in the database engines.

Tupper Lake 9 Miler 2010


Saturday was the Tupper Lake 9 Miler race. I’ve been looking forward to this race for months because last year it was the first real race I did and I was looking forward to seeing my progress. I’m in a faster boat, I’m fitter, my technique is better and I’m more used to racing. Unfortunately they announced that due to construction at “the crusher”, the normal start of the race, this year it would be a semi-loop course up and down river instead of all down river, so it won’t be directly comparable.

The weather was pretty good – a bit cool, very little wind, and it only started raining after we got in the boats to warm up. There was a huge crowd of ICF sprint kayaks, and so we would have actually preferred a bit of waves to give us an advantage over them. It turned out that most of them were in sprint boats because that’s the standard thing in Canada, rather than because they were shit hot paddlers. There were a few shit hot paddlers in sprint boats including Jim Mallory and Ken O-J and a lot of people I had no idea about.

At the start, we lined up between two buoys. There were two markers we had to round that were about 30 degrees to the right of perpendicular to the line between the buoys, so most people lined up at kind of an angle to the line. Jim and a few others actually lined up to the right of the rightmost buoy, giving themselves a shorter line to the marker, but considering how my boat turns and the traffic, I was content to be a little further to the left to approach the markers on a more obtuse angle. Except at the gun the guy beside me to my right sprints out perpendicular to the start line, cutting off me and Doug and Mike and a few others taking a more direct line to the markers. And then when I passed on the inside of him, he suddenly veered about 60 degrees to the right and slammed into me.

We reached the first marker in pretty good condition. I was on Mike Littlejohn’s side wake, Doug was on his tail, we were catching Bill, and there were only a few kayaks ahead of us, including Jim and one of the Canadians who were pulling ahead. We passed Bill before the channel.

Entering the channel, we had a bit of following seas, but with little wind it could very well be of our own making. Doug says there was a strong current coming out, but I didn’t notice it – although my GPS does record a drop in speed to under 6mph briefly. We quickly turned up river, but there didn’t seem like much percentage in skulking up the bank the way Jim was doing because there was little current and lots of weeds in close. An old guy in an old fashioned sprint boat came chugging by with excellent and effortless looking technique, and Doug was on his wake like a limpet. Mike Littlejohn got on Doug’s wake, and I was still on his side wake. I tried to pull up to Doug’s side wake, but I just couldn’t get over the one wave on to the next. The river turned, and Doug veered towards my side, and suddenly I was on his stern wake and Mike Littlejohn was trying unsuccessfully to stay on my side wake. After a while the old guy got a gap on us, and Mike dropped behind, and it pretty much stayed like that until the oxbow loop that was the turn. Doug managed to gap me once or twice but I struggled back on.

In the oxbow, it wasn’t quite as shallow as I’d feared. Kent O-J finally caught us (he’d had some trouble with the waves in the lake in his new sprint boat), and when he went by Doug put on a burst of speed to stay with him. It wasn’t successful for very long, but it was enough for him to open an insurmountable gap over me. I tried like hell to use every trick to bridge the gap, but I never got any closer.

It was along the final stretch of river that we encountered a guide boat that had been in on a dock and suddenly decided to blunder out into out path. Doug yelled at them and they slowed, but I still had to swing out around them.

We started passing the c-2s who had started in an earlier wave, and it was nice – you could pull in to thier stern wake, recover a bit, lower your heart rate and breathing, get a drink, then sprint like hell for the next one or one a few canoes up. I did most of the sixth and seventh miles like that. Doug wasn’t doing that, so he was pulling away even more. Doug was closing on three boats just tantalizingly out of reach – the old guy in the 1985 sprint boat, Kent O-J, and a guy in a light yellow Kayak Pro boat. The top two, Jim Mallory and that French Canadian guy, had finished before I was in site of the line.

I was exhausted at the end. I’d gone out a lot faster than I had at Round The Mountain, and I had nothing in the tank at the end. I ended up being third in under 50, behind the Canadian guy who’d outsprinted Jim and Doug. Jim won over 50. Mike Finear was about a minute behind me and won Touring class. Mike Littlejohn is evidently calling his boat Unlimited class now, and he finished somewhere between me and Mike F. Bill was not too far behind Mike, doing well in spite of the fact that he doesn’t paddle as much as the rest of us.

Compared to last year, this year I did 6.75 miles in 1:02, for an average speed of 6.5 mph. Last year, in a slower boat with less conditioning, I did 7.21 miles in 1:07, for an average speed of …. 6.5 mph. Hmmm. The only thing I can say in my favour is that this year, the first three miles were upstream and the last 3.75 miles were downstream, and last year the whole distance was downstream.

Update: Official results are up. Evidently as well as the three guys Doug was closing in on, there was another guy in a Marauder and a Canadian woman (so probably in a sprint boat) about a minute ahead of them. So while I was third in Men’s Under 50 Unlimited, I was actually about 9th fastest kayak. Sigh.

Memorial Day

I’m a Canadian, (Ok, I’m technically a triple citizen of Canada, the UK and the US, but in my heart I’m a Canadian.) I served in the Canadian military (Lorne Scots, Peel Dufferin and Halton Regiment, protecting downtown Brampton from the perfidious hordes of the The Argyll and Sutherland Highlanders of Canada (ASH CANs) and the Toronto Scottish Regiment (TORSCOTS)). It wasn’t much, but I feel like I can claim some small kinship with the men and women that this day, Memorial Day, is supposed to honour. Remembrance Day (11 November) means more to me, but this is the US and they do things differently here.

So keeping in mind I think of this as the US version of Remembrance Day, please remember this: more important than your day off work, more important than watching all the Memorial Day specials on tv, more important than the fireworks and parades, even more important than thanking the soldiers, sailors, marines and airmen you know individually and personally, you owe them one thing above all others. And that’s to demand that their political leaders do not waste their lives. They stand willing to give their lives to defend you and your way of life, and when their commanders order them to do so, they will not stop and ask questions, they will do what they are ordered and pay whatever price comes from it. So it is us who must stop and ask the questions. Not to ask why they did what they were ordered, because that is what a soldier must do, but why the person giving the orders did so, and did they do the right thing by doing so?

So while US and Canadian (and other NATO) soldiers are dying in Afghanistan, while US tries to extricate itself from Iraq, and while some are beating drums about Iran or worrying about North Korea’s latest batshit insane move, we have to ask “did our leaders do the right thing getting us into these wars” and “can we finish what we started out to do there, or get out of them while accomplishing enough to make it worth while” and “if we get into the next one, what will be the result and what will be the cost”? Remember those questions, and not just on Memorial Day.

Second time in the ski, not as much of a success

Jim, Stephen and I met at Seabreeze to paddle on the bay. In early afternoon, on a hot sunny day in a holiday weekend. To nobody’s great surprise, every boat in the entire universe was cruising up and down the bay, making waves. Waves were hitting us from every direction at once. I was having real problems doing anything but bracing most of the time – yeah, the boat is fine if you put it over on its side, but you’ve got to keep your body and head upright, or you’re going to go over.

I ended up into a place that has been a problem in every boat I’ve been in. There is a long stretch of break-wall with some docks and boat lifts, and the break walls act as perfect reflectors, making sure that you’re getting every boat wake at least twice with very little attenuation. I dumped of course. No worries, Stephen had already dumped several times, and he gets back into his boat in no time at all. But I’ve only remounted twice, and those were in calm conditions where I could touch the ground if I needed to. So it took me a few attempts, and a little help from Jim, but I got back in. And paddled a few metres until I got hit by another nasty set of wakes and dumped again.

This time, as I was kicking to get in, one of my knees went pop. This is a particular type of pop I’m all too familiar with. It means that the normal level of pain in my knees, which is bad enough, is about to get 100 times worse, and it’s going to be sensitive to kicking and pushing and weight bearing. I got in, but I immediately dumped again at least partly because I couldn’t push easily with that leg, and this time I didn’t want to get back in. Instead, I climbed out on one of the docks and crashed a pool party next door to borrow a phone to call Vicki.

I feel bad about quitting for the second time in two days. And I worry about whether I’ve got what it takes to paddle in the surf. But I had problems last year in a much more stable boat and got better with it, so I’m hoping I’ll get used to the ski as well.
