In my quest to squeeze more performance out of the machines as they are until the hardware upgrades arrive, I tried to upgrade the kernel on larousse, to 2.4.22 plus a patch for /dev/epoll support, which is highly recommended for memcached.
I ran a 'make oldconfig' on the config file for the stock kernel and didn't change any settings. I tried compiling the same kernel version and config on my Linux box at home (Red Hat 8.0, not quite the same as Red Hat 9.0 but close) and it boots here just great.
But, alas, larousse didn't come back up. I woke poor Jason up to reboot it so it should have fallen back to the previous kernel, but it again never came up, at least not to the network.
Obviously I'm a bit annoyed with myself, but I did take what precautions I could, and well, desperate times... :(
I don't know if the boot manager is fouled up, or just the kernel, or if something related the library troubles we had last month reared up again so it's not getting past init. Hopefully we'll get it sorted out fairly soon, but in the meantime larousse is offline.
Pliny has taken over its address and is serving www.wikipedia.org for now. (So, don't be alarmed if you try to login to larousse and get "HOST IDENFITICATION HAS CHANGED! IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!" from ssh. Just log in to pliny direct.)
I hate computers! grrr
Good news is, no more www vs en2 functionality troubles! ;)
