Normal What were you trying to do that didn't work?
Running grub2-mkconfig while an LVM2 snapshot of the root file system is present.
Please provide the package NVR for which bug is seen:
grub2-tools-2.06-77.el9.x86_64
How reproducible:
100%
Steps to reproduce
-
lvcreate -L <size> -n root-snap rhel/root lvcreate -L <size> -n var-snap rhel/var lvcreate -L <size> -n home-snap rhel/home
-
grub2-mkconfig -o /var/tmp/grub.cfg
Expected results
grub2-mkconfig exits normally and writes the specified grub.cfg file.
Actual results
[root@localhost ~]# grub2-mkconfig -o /var/tmp/grub.cfg

A grub2-mount process is also running and has a mount at /var/lib/os-prober/mount:
41668 ? Ss 0:00 grub2-mount /dev/mapper/rhel-root--snap /var/lib/os-prober/mount
[root@localhost ~]# mount | grep mount
grub2-mount on /var/lib/os-prober/mount type fuse.grub2-mount (rw,nosuid,nodev,relatime,user_id=0,group_id=0)
The mount persists after killing grub2-mkconfig with Ctrl-C and has to be cleaned up manually. The new grub.cfg is not written.
