Comment on Lenny domU Xencons by Henrik

Thanks for that information. Saved me some time!

One further problem I noticed with the console to domUs is that they don’t like at all to be shared.
It may work for a bit but leave you with a hanging console when you start a command that quickly produces a lot of output.

So if you have an “xm console ” running (e.g. in a dangling ssh connection) , make sure you disconnect it before attaching from another connection to the same vm’s console.

xenscreen is also a culprit to look out for, as it attaches automatically to every vm that you start and doesn’t show up in dom0 as a “xenconsole” process!

Comment on Mdadm Cheat Sheet by Jerry

Have you heard of bios settings changes mangling an MD raid? I built a raid with the “RAID autodetect or sata” option set. When I changed to “Raid autodetect or AHCI” option and tried to reboot my newly built Debian linux install on my new Dell T3500 my md0, md1, md2 changed to md125, md126, and md127 (discovered with a knoppix recovery CD). I gave up on that effort and tried to install debian on the RAID array without first deleting all the partitions. The Debian install found the RAIDs; I reassigned them to /boot, swap and / respectively… but now with raids MD125, MD1 and MD127. Then I couldn’t get past the linux (grub) loader. It couldn’t even find /boot. Now (using knoppis CD) mdadm -a -s can’t find the arrays. I’ll try to build them by command just for grins.
What’s the point of this email? A little whining. A little searching for confirmation that this DELL bios setting either mangles software raids or that I just had bad luck, and will succeed if I start from square-1. Cheers….

Another good thing is to leverage browser cache. It speed up page loading

Comment on Debian 6.0 Squeeze expected to be released by the end of the year… if all goes well by manmath

Yes, in all possibility Squeeze will go gold in the first quarter of 2011. But that’s Debian enterprise standard release. Desktop users can pretty happily use Squeeze testing, it’s already ready for that purpose.
