The RAID5 is recognized as /dev/mapper/nvidia_bcacfdbg The suse install made two partitions of it, one /boot and the rest as LVM. The default install would make the /boot very small (about 70MB IIRC), but I got in trouble with the first kernel update. So on my second attempt I made it much larger, 1GB, to have immense spare space. I don't foresee any bottleneck here in the near or far future. And the benefits of LVM need no explanation, do they?

You can boot from LVM in 11.2 AFAIK (even earlier versions). Whether or not that is wise is a different matter. > I have a Motherboard RAID5 made of four identical 500GB SATA drives. > The RAID5 is recognized as /dev/mapper/nvidia_bcacfdbg > The suse install made two partitions of it, one /boot and the rest as > LVM.

And the school of hard knocks proved even that to be problematic - lots of niggling little problems, although most were resolved by the first few updates. KDE4 and my particular old Nvidia video (6100) did NOT play nice. -- Will Honea

That's an interesting question. I am in a situation somewhat like Bob's, but different enough to lead me to a different answer. I run a production system, but I am the only real user. Thus I can predict future computing needs fairly well and allow time for an upgrade. Still, I prefer to upgrade every other release or sometimes every third release. But I've come to understand that I have to dedicate an old machine as a test bed. That will help. -- --- Paul J. Gans

I have tried one time to use an official SLES release, and that was "such an experience never again". Then I am more prepared to use the open variant and maybe have to live with some theoretical vulnerability (which often does not really exist in the very limited featureset that we use), and to update it once every few years. |
