Hello Scott, or anyone else affected, Accepted lvm2 into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/lvm2/2.03.07-1ubuntu1.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-focal. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: lvm2 (Ubuntu Focal) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834250 Title: update-grub complains about non-existent drives (due to cardreader) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1834250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1834250] Re: update-grub complains about non-existent drives (due to cardreader)
You can prevent lvm2 from scanning the card reader by using the global filter. Instead of using drive letters for the filter, like 'sde' which is liable to change, use the id of the device(s). E.g.: # ls -l /dev/disk/by-id/ | grep sd[e-h] lrwxrwxrwx 1 root root9 Apr 13 11:06 usb-Generic_USB_CF_Reader_058F312D81B-0:1 -> ../../sdf lrwxrwxrwx 1 root root9 Apr 13 11:06 usb-Generic_USB_MS_Reader_058F312D81B-0:3 -> ../../sdh lrwxrwxrwx 1 root root9 Apr 13 11:06 usb-Generic_USB_SD_Reader_058F312D81B-0:0 -> ../../sde lrwxrwxrwx 1 root root9 Apr 13 11:06 usb-Generic_USB_SM_Reader_058F312D81B-0:2 -> ../../sdg Since all card reader slot device ids contain the unique 'Reader_058F312D81B', you can use the following global filter in lvm.conf.

[Bug 1834250] Re: update-grub complains about non-existent drives (due to cardreader)
I'm running 19.10 x64 (up to date as of today), LVM setup. Originally installed 19.04 and upgraded. This affects me too. Or, affected rather, because after following advice from comment #9 above it seems fixed. Details follow. ``` $ sudo update-grub2 Sourcing file `/etc/default/grub' Sourcing file `/etc/default/grub.d/init-select.cfg' Generating grub configuration file ... /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found Found linux image: /boot/vmlinuz-5.3.0-29-generic Found initrd image: /boot/initrd.img-5.3.0-29-generic Found linux image: /boot/vmlinuz-5.3.0-26-generic Found initrd image: /boot/initrd.img-5.3.0-26-generic /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found /dev/sda: open failed: No medium found ``` It goes on, but I'm skipping it. ``` $ lsblk nvme0n1 259:00 931.5G 0 disk ├─nvme0n1p1 259:10 512M 0 part /boot/efi ├─nvme0n1p2 259:20 732M 0 part /boot └─nvme0n1p3 259:30 930.3G 0 part └─nvme0n1p3_crypt 253:00 930.3G 0 crypt ├─ubuntu--vg-root 253:10 929.3G 0 lvm / └─ubuntu--vg-swap_1 253:20 976M 0 lvm [SWAP] ``` Above I'm skipping bunch of loop## from output of lsblk. The Ubuntu "Disks" app identified the /dev/sda as "Generic- SD/MMC". It seems it's a built-in card reader of my ThinkPad. I decided to follow comment #9 above to filter out that device from LVM. And, advice from comment #9 fixed the issue! Thanks a lot Zer00Cool! What I did exactly is: 1. grep for "global_filter" in lvm.conf - that file is really long... ``` $ grep -Fn "global_filter" /etc/lvm/lvm.conf 142:# Configuration option devices/global_filter. 146:# Use global_filter to hide devices from these LVM system components. 148:# global_filter are not opened by LVM. 150:# global_filter = [ "a|.*/|" ] ``` 2. After the commented out "global_filter" setting (line 150 in my case), I added the following: ``` global_filter = [ "r|/dev/sda|" ] ``` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834250 Title: update-grub complains about non-existent drives (due to cardreader) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1834250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you, Zer00Cool, it helps.

Hi, Same problem here. I want to skip the GRUP so I modify the grub file, but once I run the command sudo update-grub the terminal show me the same issue. Thanks and if I can do anything tell me.
