[Bug 1190295] Re: 2.6.32-47 kernel update on 10.04 breaks software RAID (+ LVM)
Closing this bug with Won't fix as this kernel / release is no longer supported. Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04) Thanks! ** Changed in: linux (Ubuntu) Status: Incomplete => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190295 Title: 2.6.32-47 kernel update on 10.04 breaks software RAID (+ LVM) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1190295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

:: could you confirm that these would be various different kernel versions over time, and not ONLY on the 46 to 47 update? That's probable. IIRC, my RAID1 MD devices have been blowing up inexplicably over the past year, and I tend to stay quite current on patches, applying them each week regardless. :: Have you seen this when doing any other reboots (not after system updates)? No, it really seems related to kernel updates. The system I reported on had been pulled out of production for hardware updates, so was powered off. In the time it took to replace hardware and test the new system new kernel patches had come out so I suspected things were going to get broken as soon as I applied the kernel patches. :: do you also see the MD degraded raid prompt and if so how do you respond? No, I only ever see the Continue to wait; or Press S to skip mounting or M for manual recovery. Nothing about MD degraded. :: are the device links in /dev/vgname/lvname present? :: are the LVs listed in the output of 'lvs' and what are their state? :: are the PVs which are backed by md0 present in 'pvs' and what are their state? Don't remember about /dev/vgname. lvs, vgs and pvs all were sporadic in output, sometimes complaining of leaked memory, sometimes displaying my LVs and PVs. It was unstable. :: are the volumes present in the 'dmsetup ls' output? Never used 'dmsetup ls'. :: what is the actual state of md0 as show in 'cat /proc/mdstat'? In the unstable state, after rebooting with patched kernel and RAID+LVM borked, sometimes mdstat would say something about the device not existing and then issuing it again would show /dev/md_d0 -- which is not the correct MD device. Sometimes I would have to issue mdadm -S /dev/md_d0 and then mdadm --examine --scan to restart it. I have never seen Linux software raid fail this badly. Hopefully it's fixed soon as I know from experience MD has historically been bulletproof. I have never had such problems before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190295 Title: 2.6.32-47 kernel update on 10.04 breaks software RAID (+ LVM) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1190295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1190295] Re: 2.6.32-47 kernel update on 10.04 breaks software RAID (+ LVM)
It's possible that the patches which were linked are not related. They're not in the delta between the two versions which are listed. Here are some questions to try to narrow down the field of potential issues. 1. You mention that this occurs on various upgrades, could you confirm that these would be various different kernel versions over time, and not ONLY on the 46 to 47 update? 2. Have you seen this when doing any other reboots (not after system updates)? (such as might occur if this was a boot race - which could only shows up because the first boot after an update performs additional operations) 3. When this occurs you mention that you see the 'M' for manual recovery, do you also see the MD degraded raid prompt and if so how do you respond? 4. On taking the 'M' that option LVM slices are missing which are served from the RAID, can you provide the following information for missing LVs (backed by md0): A) are the device links in /dev/vgname/lvname present? B) are the LVs listed in the output of 'lvs' and what are their state? C) are the volumes present in the 'dmsetup ls' output? D) are the PVs which are backed by md0 present in 'pvs' and what are their state? E) what is the actual state of md0 as show in 'cat /proc/mdstat'? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190295 Title: 2.6.32-47 kernel update on 10.04 breaks software RAID (+ LVM) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1190295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I see and I'll try to flie the new report as soon as possible, even though I think it is the same cause as this one. I've had a look at the kernel log and see that only two patches affected the md component between 2.6.32-46 (working kernel) and 2.6.32-47 (broken kernel, reported in this bug): https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-2.6.32.yid=c28f366a6ef9b6e14e069e7d750c32d7354e https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-2.6.32.yid=372994e9fd5cadbacdfcc8724b590193d136c947 A notification to the author might help solve this even quicker. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190295 Title: 2.6.32-47 kernel update on 10.04 breaks software RAID (+ LVM) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1190295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
