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 root 9 Apr 13 11:06 usb-Generic_USB_CF_Reader_058F312D81B-0:1 -> ../../sdf lrwxrwxrwx 1 root root 9 Apr 13 11:06 usb-Generic_USB_MS_Reader_058F312D81B-0:3 -> ../../sdh lrwxrwxrwx 1 root root 9 Apr 13 11:06 usb-Generic_USB_SD_Reader_058F312D81B-0:0 -> ../../sde lrwxrwxrwx 1 root root 9 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. "r|/dev/disk/by-id/.*Reader_058F312D81B.*" # filter out card reader slots Good luck! -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lvm2 in Ubuntu. https://bugs.launchpad.net/bugs/1834250 Title: update-grub complains about non-existent drives (due to cardreader) Status in lvm2 package in Ubuntu: Confirmed Bug description: sudo update-grub Sourcing file `/etc/default/grub' Sourcing file `/etc/default/grub.d/init-select.cfg' Generating grub configuration file ... /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found Found linux image: /boot/vmlinuz-5.0.0-17-generic Found initrd image: /boot/initrd.img-5.0.0-17-generic Found linux image: /boot/vmlinuz-5.0.0-16-generic Found initrd image: /boot/initrd.img-5.0.0-16-generic /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found /dev/sdc: open failed: No medium found /dev/sdd: open failed: No medium found /dev/sde: open failed: No medium found /dev/sdf: open failed: No medium found Adding boot menu entry for EFI firmware configuration done -- lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 3.7T 0 disk ├─sda1 8:1 0 512M 0 part /boot/efi ├─sda2 8:2 0 732M 0 part /boot └─sda3 8:3 0 3.7T 0 part └─sda3_crypt 253:0 0 3.7T 0 crypt ├─kubuntu--vg-swap_1 253:1 0 976M 0 lvm [SWAP] └─kubuntu--vg-root 253:2 0 3.7T 0 lvm / sdb 8:16 0 3.7T 0 disk └─sdb1 8:17 0 3.7T 0 part sdg 8:96 0 7.3T 0 disk └─sdg1 8:97 0 7.3T 0 part /media/scott/8TB Ext Drive sr0 11:0 1 15.7G 0 rom -- cat /etc/default/grub GRUB_DEFAULT=0 GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on" GRUB_CMDLINE_LINUX="" ProblemType: Bug DistroRelease: Ubuntu 19.10 Package: grub2-common 2.02+dfsg1-12ubuntu3 ProcVersionSignature: Ubuntu 5.0.0-17.18-generic 5.0.8 Uname: Linux 5.0.0-17-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu3 Architecture: amd64 CurrentDesktop: KDE Date: Tue Jun 25 15:05:29 2019 InstallationDate: Installed on 2019-06-14 (10 days ago) InstallationMedia: Kubuntu 19.10 "Eoan Ermine" - Alpha amd64 (20190614) SourcePackage: grub2 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1834250/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
