zen resurrection

Well, Ubuntu 12.04LTS release comes out....I had done 'lhaven' using a beta 2, so had thought it would be nice. But, things didn't work. I tried the regular installer, and it wouldn't start. I then tried the alternate installer....which it installed everything, but then it wouldn't boot.

Later I come across discussion that there's a known problem with Nvidia cards with 2 or more GBs. Well, I have an Nvidia card with 2GB. In the meantime, I had also been researching the idea of someday running a Xen server, so that I could use PCI passthru, because there was a question on whether I could use the RR62x Windows array from Ubuntu or perhaps getting GPU access for BOINC.

So, I try XCP. During the process, I build the rr62x driver for it and at least get access to my data temporarily.... so I try to find somewhere to copy the Oops!Backup volume that's more accessible....but its over 1TB in size, and the only way to get that kind of space is to turn a 1TB RAID1 on ORAC into a RAID0. So, I do that.

But, just before I get to where I can attempt to use it....one of the drives dies, and its lost.

While playing around with XCP, I decided to get a small SSD drive to use for the OS, and dedicate the 1.5TB RAID array (using mdadm) to be the datastore for Xen. But, after an initial windows install, I run into a problem....I need a client to access it with. Don't know why that didn't occur to me. I look at various options at setting up a small diskless client of some sort....but then, discover that my hardware lacks the CPU features it needs to do what I had hoped with Windows under Xen.

Around this time, FreeBSD 9.0 has become a new OS that we're supporting in production at work. It had been many years since I've tinkered with FreeBSD, and I wasn't currently running such a system at home. Though had often thought about doing so for its ZFS support.

Now instead of subjecting some poor random forum to a long rambling thought, I will try to consolidate those things into this blog where they can be more easily ignored profess to be collected thoughts from my mind.
