Getting below error message when trying to mount a filesystem:
# mount /dev/mapper/vg-lv /mnt mount: /mnt does not contain SELinux labels. You just mounted an file system that supports labels which does not contain labels, onto an SELinux box. It is likely that confined applications will generate AVC messages and not be allowed access to this file system. For more details see restorecon(8) and mount(8). mount: /dev/mapper/vg-lv mounted on /mnt.
Even though the output shows the device was mounted, it was actually not, which can be confirmed with commands such as df or mount.
The partition’s SELinux context is incorrect. The correct context needs to be set in order to be able to mount the partition.
Relabel the filesystem by creating /.autorelabel followed by a reboot or perform restorecon on the filesystem:
# touch /.autorelabel # reboot
# restorecon -Rv /
