I am running an Ubuntu 10.04 server which has a fairly early version of madm (straight from repository) and it has the problem that so many people have written about when rebooting or starting up. I have to have about 3 goes as it keeps complaining that one of the drives (by UUID) is not present. It is the drive listed in fstab, not the arrays. All of a sudden after a few attempts it starts up OK. Many of the articles refer to upgrading to mdadm 3.1.5 from the source code as a good fix. I haven't actually seen anyone write about the upgrade process itself, so my question boils down to asking if I can remove the repository version with apt-get, then install the new version from source on a system that is actually operating?? Is anyone sure if it will work with Ubuntu 10.04 server?? Does anything else need upgrading. I would certainly appreciate any advice. Mike Australia
