Unfucking ZFS after moving disks

OpenZFS, it turns out, can react very poorly to a reshuffling of the disks. In one zpool I had six disks, arranged as 3 mirrored VDEVs, physically arranged in two external enclosures. One of the enclosure has 4 slots, the other 2. Two of the VDEVs were in one enclosure, the third in the second. This isn’t ideal: one enclosure failure will offline the whole zpool. To fix this, I got ahold of another 4 slot enclosure to spread the VDEVs around. That’s when things went a little fucky.

Kiwicon 11 Day 2 Afternoon

Tracking the Watchers: Practical Tooling Paul McMillan We are going to build a map of radio systems in your city - this is a work in progress, so if you want to use this you’ll need to do some work yourself as well. The systems Paul are working on are P25 radios, which are trunking systems wth centrally controlled channels and frequencies. Intercept nodes, scattered around the city, are: BladeRD 2.

Kiwicon 11 Day 2 Morning

Last night was rounded out nicely by a visit to (thelibrary.co.nz/)[the Library], which offered a civilised volume, a nice mocktail, and some delicious cheeses. What more could a man ask for? Well, I guess I can think of several things, starting with the winning Lotto numbers, but they’re not on offer. After trundling off to bed at a sensible hour, I’m ready to leap once more into the breach, dear friends.

The day commences with a reading from Machines of Loving Grace and some administrivia, including mentioning the sponsors. Which metl probably should have done yesterday.

Kiwicon 11 Day 1 Morning

After a much-deserved rest, the good folks of the Crüe return for the 11th Kiwicon, styled Kiwicon 2038AD and with a nifty cyberpunk/Blade Runner theme. We have gloomy colour schemes and mirror shades. We’re returning to the Michael Fowler Centre so as to allow a couple of thousand of us to show up and learn more about the terrors of the what happens when thinking rocks go wrong.

SOHO Gluster for Great Reliability

I was inspired by attending Angus Lees’ garage Kubernetes at linux.conf.au 2018; not in the direct way of setting up Kube at home (although that’s on my to-do list); rather, to solve what Angus mentioned in passing as the biggest pain point for lab/SOHO environments: storage. Storage is still a SPOF1 for most SOHO-type environments.

There’s a good reason for that: distributed systems are hard. Distributed storage is the hardest part of that problem. But it’s also the most worthwhile problem to solve; if you can have reliable distributed storage, you’ll never wake up to find a note from your 5 year old bemoaning that she can’t watch TV again.

NZIFF Tranche 1

Another fine start to the Alliance Français French Film Festival. Last year I binged on perhaps two dozen movies and, really, it was far too many. This year I’ve paired back a bit, which will no doubt mean I miss some good ones, but equally will mean I’m not too overloaded to even think about them properly.

The only sour note is that, as last year, the change in director in 2017 seems to have largely trashed the children’s film selection. Historically a bit of a highlight, it’s become desperately mediocre.

Le bâtiment

Anouk a gagné. Elle a gagné beaucoup d’argent, mais ell n’a rien dit à personne. Pourqoui? C’est difficile à expliquer. Toute sa vie, sa famille a été pauvre. Sa vie a été gâché par la pauvrité: ses écoles étaient les écoles pauvres, sa nourriture, ses passions, ses vêtemenets, etc. La pauvrité a tout façonné. Mais elle a plus de chance que les autres de sa banlieue: elle a un boulot solide.

LCA 2018 Day 5

Another hot, sticky day in Sydney. The climate is my least favourite thing about the place.

Surprising amounts of the city apparently close for “the public holiday”, as the organisers are referring to it, in an effort to maintain neutrality on the local arguments around whether the current form of celebrating the European colonisation of Australia is the right one.

As an aside, mentioning I’m staying in Redfern elicits the odd interesting response from people who think this is basically equivalent to checking into a hotel in a war zone; I was told there would be riots here on Friday, which doesn’t in fact seem to be the case. While the locals are not exactly Abbot voters, the only dire predictions of danger that appear to be accurate are Sydneysiders warning of aggressive gentrification.

LCA 2018 Day 4

Sydney may have a lot of things going for it, but the climate is definitely amongst of them. Still, in spite of the hot, sticky weather, I’m enjoying wending my way through the streets of Redfern every morning; with it’s tiny old row houses and narrow alleys it would seem to be more what you’d find in the heart of an old European city like York; then I exit onto some of the stunningly designed newer buildings provides a sharp and delightful contrast.

I have no idea how anyone affords to live here, though.

LCA 2018 Day 3

Another balmy day in Sydney. This is… not my ideal climate, shall we say. But hey, I saw a big ol’ bat flying around in the wild, which was cool for me and probably completely uninteresting to the locals.

LCA 2018 Day 1

This year LCA comes to Sydney, marking the first time I’ve been here since I was maybe 8 or 9. The locals are shocked; apparently the idea one has not come to Sydney is inconceivable. So far I’ve been enjoying the well-integrated public transport with fast, quiet high-speed trains (20 minutes from the airport to Redfern), been freaked out by the cost of rent (Redfern, a location where there are signs asking people not to shoot up in front of children, has apartments renting north of $1200 a week), and oppressed by the weather. Sydney is vast, full of Things and Stuff, and I doubt I’ll see more than the tiniest fraction of it this week.

This year I’m offering many thanks to OSS for sponsoring my ticket.

B-Sides Wellington Day 2

Another sunny day in Wellington for B-Sides. Not that this is anything exceptional about this, the weather is alwys like this why do you ask? Someone won the badge challenge already! Influencing Meat Puppets through Memes Simon “bogan” Howard There are some Kiwicon traditions that have been carried across to B-Sides, and splendid headwear is one of those things: Simon prowls the stage is a blinged out admirals hat whose magnificence cannot be described with mere words.
