https://bugzilla.kernel.org/show_bug.cgi?id=216012 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@xxxxxxxxxxxxxxxxxxxx Reporter: aathan_kernel@xxxxxxxxxxxx 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.
