ADVICE: Don’t upgrade to Ubuntu Feisty Fawn if you’re using LILO on a degregated software RAID. Resync first, as told by this forum posting… I had to boot an old kernel (and who remembers which key to press to show the LILO menu?) The kernel packages weren’t able to build the initramfs and running lilo didn’t help, either. Resyncing was the key to success, though.
Our Compaq ProLiant ML 350 G2 is our “Achilles’ heel“. We don’t have spare parts for this machine. It’s the only SCSI system, running 3 Disks as a hardware RAID 5. The controller is some kind of Compaq SMART Array controller. Well, it didn’t work anymore after one boot. All the data still there, mirrored and all… but we couldn’t get at it. A few calls later we knew that a new, original controller would be available in 5 to 10 business days:-( Later that day, we found out that all Compaq SMART Array controller should be data compatible! We thus searched on Ebay et all, but didn’t find a local offer. We ordered a card from Germany, but they didn’t react on phone calls or faxes. Ramon did some more Ebay browsing and found one shop selling Compaq ProLiant ML 360 Rack servers for a reasonable price. We did only realize that a rack server probably will have an onboard SCSI controller when we got it. Well, it didn’t provide a SCSI cable connector, but only 2 DH slots. Problem was, that the controller did complain about changed order of disks, and changing disks didn’t help. It was only the last combination we tried that made the server boot with the degregated RAID 5 Array.
On of the most useful Feisty Fawn improvements is the integration of avahi. Using MDNS, you may address systems on the same network segment using a hostname instead of IP addresses. It’s dead simple: hostname.local:
shuerlimann@leni:~/cyt.ch/projects$ ping otherhost.local
PING otherhost.local (192.168.200.225) 56(84) bytes of data.
64 bytes from anon-client225.intern.example.com (192.168.200.225): icmp_seq=1 ttl=64 time=36.5 ms
Just make sure you allow incoming connections on UDP port 5353.
It looks like systems updated from Edgy Eft don’t get this feature by default. Please give me some hints how to do that if you know how to do it:-)
If you don’t have unpartitioned space on your drive, but would like to delete an existing partition and use this space, here’s the HOWTO…
The ‘use larges free space’ option in the KubuntuFeisty Fawn partitioner is only available if there is some unpartitioned space. Unfortunately, you can’t choose the manual partitioner, delete a partition and choose the mentioned method. The IMHO simplest method is to close the installer, open up konsole (ALT-F2 -> konsole), start cfdisk (‘sudo cfdisk /dev/hda’ where /dev/hda is the drive you’d like to partition) and delete the partition. Then start the installer again. Now the ‘free space’ method should be available.
There might be a possibility to use the visual partitioner instead of cfdisk, but I don’t know. Leave a comment if YOU do…
