On a freshly installed system, booting latest upstream kernels causes the system to drop into emergency shell. The reason for dropping into emergency shell is system is unable to mount /home partition. The system was able to boot properly on v5.18 kernel, but failed to boot v5.19 and 6.2-rc8 kernels. On the recent or failing kernels, I see the below msg when kernel drops into emergency shell. lvm[1370]: /dev/sda3 excluded: device is not in devices file. lvm[1370]: WARNING: no autoactivation for /dev/sda3: system.devices naa.60050768108001b3a800000000000097 current missing device id. systemd[1]: dev-mapper-rhel_ltcden3\x2d\x2dlp9\x2dhome.device: Job dev-mapper-rhel_ltcden3\x2d\x2dlp9\x2dhome.device/start timed out. systemd[1]: Timed out waiting for device /dev/mapper/rhel_ltcden3--lp9-home. systemd[1]: Dependency failed for /home. systemd[1]: Dependency failed for Local File Systems. systemd[1]: Dependency failed for Mark the need to relabel after reboot. systemd[1]: selinux-autorelabel-mark.service: Job selinux-autorelabel-mark.service/start failed with result 'dependency'. systemd[1]: local-fs.target: Job local-fs.target/start failed with result 'dependency'. systemd[1]: local-fs.target: Triggering OnFailure= dependencies. systemd[1]: home.mount: Job home.mount/start failed with result 'dependency'. systemd[1]: dev-mapper-rhel_ltcden3\x2d\x2dlp9\x2dhome.device: Job dev-mapper-rhel_ltcden3\x2d\x2dlp9\x2dhome.device/start failed with result 'timeout'. lsblk o/p when system has fallen into ememrgency shell (aka bad kernel) NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 0 100G 0 disk â??â??sda1 8:1 0 4M 0 part â??â??sda2 8:2 0 1G 0 part /boot â??â??sda3 8:3 0 99G 0 part â??â??rhel_ltcden3--lp9-root 253:0 0 63.8G 0 lvm / â??â??rhel_ltcden3--lp9-swap 253:1 0 4G 0 lvm [SWAP] sr0 11:0 1 1024M 0 rom lsblk o/p when system boots normally on v5.18 or earlier kernels NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 0 100G 0 disk â??â??sda1 8:1 0 4M 0 part â??â??sda2 8:2 0 1G 0 part /boot â??â??sda3 8:3 0 99G 0 part â??â??rhel_ltcden3--lp9-root 253:0 0 63.8G 0 lvm / â??â??rhel_ltcden3--lp9-swap 253:1 0 4G 0 lvm [SWAP] â??â??rhel_ltcden3--lp9-home 253:2 0 31.2G 0 lvm /home sr0 11:0 1 1024M 0 rom lvdisplay o/p when system has fallen into emergency shell (aka bad kernel) Devices file sys_wwid naa.60050768108001b3a800000000000097 PVID iws5FZqBFBVE12w874dFuppLWkQUyEcb last seen on /dev/sda3 not found. lvdisplay o/p when system boots normally on v5.18 or earlier kernels --- Logical volume --- LV Path /dev/rhel_ltcden3-lp9/swap LV Name swap VG Name rhel_ltcden3-lp9 LV UUID pzxuKG-ofVC-7jBY-HXn9-RDPN-G3hP-K5gdcI LV Write Access read/write LV Creation host, time ltcden3-lp9, 2023-01-24 09:44:21 +0530 LV Status available # open 2 LV Size <4.01 GiB Current LE 1026 Segments 1 Allocation inherit Read ahead sectors auto -
