Linux: Run fsck On LUKS (dm-crypt) Based LVM Physical Volume

To run fsck on a LUKS (dm-crypt) based LVM physical volume on a Linux system, you will need to first unlock the LUKS volume and then activate the LVM volume group.

Here's an example of how to run fsck on a LUKS based LVM physical volume:

1. Unlock the LUKS volume:

cryptsetup luksOpen /dev/sda1 lvm

This will unlock the LUKS volume on /dev/sda1 and map it to the device /dev/mapper/lvm.

2. Activate the LVM volume group:

vgchange -ay

This will activate all the LVM volume groups on the system.

3. Run fsck on the LVM logical volume:

fsck /dev/mapper/vg0-lv0

This will run fsck on the logical volume lv0 in the volume group vg0.

4. When you are finished, close the LUKS volume and deactivate the LVM volume group:

cryptsetup luksClose lvm
vgchange -an
