Date: Sat, 21 May 2022 17:52:41 +0000	[thread overview]

            Bug ID: 216012
           Summary: Data loss on VirtualBox VMs
           Product: File System
           Version: 2.5
    Kernel Version: Linux ubuntu 5.13.0-35-generic #40-Ubuntu SMP Mon Mar
                    7 08:03:10 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: high
          Priority: P1
         Component: ext4
          Assignee: fs_ext4@kernel-bugs.osdl.org
          Reporter: aathan_kernel@memeplex.com
        Regression: No

From recent kernel and/or vbox versions forward, I've started to experience
data loss and/or filesystem corruption on a regular enough basis that I've
enabled fsck on every reboot. Mac OSX hosted VM.

It's not clear to me what the source of the problem is, but it may not be ext4
itself vs some element of the block device drivers and/or related hypervisor
facilities.
