commit ad720ad788be1d653da31be36fca5e886e314ddb Author: Pavel Cahyna Date: Thu Aug 24 11:41:25 2023 +0200 Remove the lvmdevices file at the end of recovery The file /etc/lvm/devices/system.devices restricts LVM to disks with given (hardware) IDs (serial numbers, WWNs). See lvmdevices(8). Unfortunately, when restoring to different disks than in the original system, it will mean that LVM is broken in the recovered system (it won't find any disks). Therefore it is safer to remove the file to force the old behavior where LVM scans all disks. This used to be the LVM default (use_devicesfile=0). diff --git a/usr/share/rear/finalize/GNU/Linux/230_remove_lvmdevices.sh b/usr/share/rear/finalize/GNU/Linux/230_remove_lvmdevices.sh new file mode 100644 index 00000000..a51e6bca --- /dev/null +++ b/usr/share/rear/finalize/GNU/Linux/230_remove_lvmdevices.sh @@ -0,0 +1,25 @@ +# Adapted from 260_rename_diskbyid.sh + +# Remove /etc/lvm/devices/system.devices +# The file restricts LVM to disks with given (hardware) IDs (serial +# numbers, WWNs).
