Today My Wife Lost Her Marbles
She lost them while thinking about the snack she was about to have. Somehow, nachos, cheddar cheese and beans made her laugh for over 10 minutes. Hysterical, uncontrollable, almost painful looking laughs. When she finished, she told me to write this down. So, as a dutiful husband, I have.
“It’s true, I did laugh over my beans.”
The bubble is about to pop
The Dubai property speculation bubble is about to pop. Aldar, a major developer, is looking to restrict the ability of customers to re-sell their property purchases. This comes on the heels of the decisions by Nakheel to prevent people who have purchased into the Trump project here from selling for a full year after purchase. All in all, what this means is there’s going to be a clamp-down on the silly profits that have been fueling the bubble. Which in turn means that the investors are going to bail out before more “controls” are added to the market, and the market will “correct”. The banks aren’t going to like this…
Never Talk To The Police
Happy 60th Dad!
So, in truth, this isn’t my image at all. It was taken by our wedding photographer, Robin Lynn. I was trying to find a fitting photograph for today, and I couldn’t. I really wanted something that had the both of us in it and was a personal moment of some kind – which means I have to rely on others to take the pics. I’ve been out of the country so long, it’s hard to find good ones. So finally I settled on this – a few minutes after my wedding, giving my father a well deserved hug for the years of support and dedication he has shown to me.
I love you dad. Happy 60th Birthday! Here’s to many more!
Samsung Drive Warranty
So, now I get to find out how good Samsung is with drive warranty work. One of the drives in my home ZFS file server went offline with “too many errors”, so I pulled the drive, and did drive-wide read-write tests. Consistent failure across three tests. So, I’ve got an email into Samsung ME to see what it’s going to take to replace the drive. I’m hoping they aren’t as bad as Western Digital.
Adding SSD to OpenSolaris on the cheap
Solid State Disks are all the rage right now for their low seek time, high IOPS ratings and low power consumption. However, they cost an arm and a leg at the moment. NewEgg charges $675 for their cheapest 64GB STA device, which works out to be $10.50/gb. Their cheapest 32GB drive is $359.00, which is $11.21/gb.
You can’t currently buy 64GB CompactFlash cards (or, I haven’t seen any) but you can get 32GB cards for $127.00 each. So, a CF->SATA adapter is $31.99 from addonics, which yeilds $158.99 for a 32GB drvice – not bad at just under half the price. I haven’t actually ordered any of this – it’s all just speculation – but if you were to use this as a slog or a cache device for a relativley slow ZFS array, you could probably get a decent speed boost.
You can of course go with an CF->IDE adapter, if you have free IDE ports laying around, the adapters are $22.99. This makes a 32 GB SSD cost $149.99 – which is $5 under Transcend’s IDE SSD, which isn’t nearly as appealing. At that price, I’d probably just get the pre-built one and be done with it.
Remember with all of this, if you have extra CF cards laying around, you might be able to work out some of this even cheaper.
Sun Cluster – with local ZFS disks
So, I’ve been grinding away on this for awhile now, and it’s come to light that the solution I’m trying to use won’t work. Yesterday, after many reconfiguration attempts, I got everything running – or so I thought. An AVS mirrored zpool, a valid Sun Cluster Express install with configured resource groups and logical hostnames, etc. The problem was that in a cluster environment, the AVS configuration database has to be on shared storage, like a shares iSCSI volume, a shared SCSI array, or the like. Of course, the point of this whole exercise was that the two nodes would be independent. Having to use a shared filesystem kinda kills that.
Here’s the relevant forum post, and here’s a really nice writeup for how to do all of this inside VirtualBox.
