+    Physical volume     /dev/md4
+    Physical extents    0 to 1907687
+```
+
+1. Format the logical volume as ext4 
+
+```
+mkfs -t ext4 /dev/davidahw2-vg4/lv0
+```
+
+2. Create a libvirt x86 64bits Ubuntu 22.04 machine mounting a LVM logical volume
+
+```
+<controller type='scsi' index='1' model='virtio-scsi'><driver queues='8' iothread='2'/></controller>
+
+
+<disk type='block' device='disk'>
+      <driver name='qemu' type='raw'/>
+      <source dev='/dev/davidahw2-vg4/lv0'/>
+      <target dev='sdd' bus='scsi'/>
+      <blockio logical_block_size='512' physical_block_size='4096'/>
+      <address type='drive' controller='1' bus='0' target='1' unit='0'/>
+</disk>
+```
+
+
+**On the guest**
+
+3. Mount libvirt/qemu provided block device /dev/sdd as ext4 partition
+
+```
+mount /dev/sdd /mnt/test
+```
+
+4. Write **27G file** or larger **on the guest** causing the **2nd checksum to be different**
+
+```
+sync; head -c 27G </dev/urandom >myfile; sha256sum myfile; sha256sum myfile
+8d3b4b263961d2c510390f99879be89b4b9134dc588139ede75573be1590115b  myfile
+a8e886b3c39d9b4721e582c5e2ca25c76ff6561750ac6dc7aa7e70404661d1cf  myfile <== ERROR: Inconsistent checksum
+```
+
+5. Write **26G file** or larger **on the guest** and **both checksum are the same**
+
+```
+sync; head -c 26G </dev/urandom >myfile; sha256sum myfile; sha256sum myfile
+598ac5da9b5bfa14d0ee664ae2590e09da772cba64cbc83ec049a656223c9401  myfile
+598ac5da9b5bfa14d0ee664ae2590e09da772cba64cbc83ec049a656223c9401  myfile <== CORRECT: Consistent checksum
+```
+
+**Important**: 
+- With the VM shutdown, the same commands on the same mounted ext4 partition **on the host** has consistent checksum every time for file sizes from 20G to 40G.
+- The disk has no sign of failure (no badblocks reported to the filesystem, MD raid reports a healthy raid setup, smart reports on error)"""
