Sorry, but in the moment it will not be a good idea to destroy my RAID again only to know, if this would work also with new install. I have several OS Systems on the Raid besides ~ 1 TB data. It would take me days of work to test and bring my machine back to state of before via Backup. I need it currently every day an am not able to.
I have already tested was P. Susi created to fix that bug. You can trust it works and implement as it is. Fact is: if you don't implement susi's fix ubuntu installs will still TOTALLY fail if you want to install on extended partitions of a Raid. If you implement it only can improve. What i can imagine to do, is to test with a life CD, updated to include fix, if the Raid is mounted and accessible, because either this did not work properly as far as i can remember. But please don't ask me to destroy my RAID for a further test. Thank You. kind regards Josef 2013/8/18 Launchpad Bug Tracker <1093...@bugs.launchpad.net> > ** Branch linked: lp:~ubuntu-branches/ubuntu/precise/multipath-tools > /precise-proposed > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1093918 > > Title: > grub-probe auto-detection fails on raid > > Status in “multipath-tools” package in Ubuntu: > Fix Released > Status in “multipath-tools” source package in Precise: > Fix Committed > Status in “multipath-tools” source package in Quantal: > Triaged > > Bug description: > kpartx was mapping the entire extended partition then stacking the > logical partitions on that device.
