-Data inconsistency on LVM logical volume mounted as partition on ubuntu guest, when the written file's size is equal or greater than 27G.
-Description of problem:
-On the guest, writing a 27Gib file or larger result in inconsistent file checksum upon subsequent read.
-Steps to reproduce:
-**On the host**
-
-0. Create a LVM logical volume on a Linux RAID 1 (with 1 disk only)
-
-```
- --- Logical volume ---
-  LV Path                /dev/davidahw2-vg4/lv0
-  LV Name                lv0
-  VG Name                davidahw2-vg4
-  LV UUID                5FbDcl-eSDe-7cXL-22tj-Lg6O-79AL-4Gq7gx
-  LV Write Access        read/write
-  LV Creation host, time davida-hw2, 2021-12-06 16:45:00 +0800
-  LV Status              available
-  # open                 1
-  LV Size                <7.28 TiB
-  Current LE             1907688
-  Segments               1
-  Allocation             inherit
-  Read ahead sectors     auto
-  - currently set to     256
-  Block device           253:4
-
-  --- Segments ---
-  Logical extents 0 to 1907687:
-    Type                linear
-    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)
