Andy's pointed me at the code in question; it's clear that support is simply missing. ** Changed in: grub2 (Ubuntu) Importance: Undecided = Medium ** Changed in: grub2 (Ubuntu) Status: Incomplete = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1206238 Title: grub2 LVM support does not handle MD raid1 style mirrored volumes, completely ignoring such volumes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1206238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1206238] Re: grub2 LVM support does not handle MD raid1 style mirrored volumes, completely ignoring such volumes
It is hard to get the machine in question into this state again, to get the explicit output from the grub ls command. It would list all my partitions other than the one which was switched to raid1, which was absent en-toto. As for configuration. This is a pure LVM setup, using the MD raid personality for raid:1 underneath. There is no mdadm configuration as they are built by LVM. Looking at that device in dmsetup table it looks something like this: datavg-home: 0 524288000 raid raid1 3 0 region_size 1024 2 252:6 252:7 252:8 252:9 So it drops into the following piece of grub_lvm_detect(): else if (grub_memcmp (p, raid, sizeof (raid) - 1) == 0 (p[sizeof (raid) - 1] = '4' p[sizeof (raid) - 1] = '6') p[sizeof (raidX) - 1] == '') { Not that this specifically only handles three types of raid:N 4, 5, and 6. With this form of symetric mirroring we have raid:1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1206238 Title: grub2 LVM support does not handle MD raid1 style mirrored volumes, completely ignoring such volumes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1206238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Phillip -- all of the LVM objects other than the ones of type RAID1, it simply has no support for knowing they are valid nor how to read them. ** Changed in: grub2 (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1206238 Title: grub2 LVM support does not handle MD raid1 style mirrored volumes, completely ignoring such volumes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1206238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Please explicitly list the output rather than summarize it, as well as describe your configuration. Do you have lvm on top of md raid, or are you having lvm do the mirroring? Please show the output of mdadm -D on the raid1. ** Changed in: grub2 (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1206238 Title: grub2 LVM support does not handle MD raid1 style mirrored volumes, completely ignoring such volumes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1206238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
