I use the phrase "linux install" to refer to a linux installation on a usb
stick,
a hard drive, or any other storage medium, including in virtualbox or similar.

Using a 64 bit ext4 file systems requires using a kernel that supports it.
To create a 64 bit ext4 files system, either it must be specified on the mkfs
command line, or it must be specified in /etc/mke2fs.conf under the features
for ext4.
I was leader of the qa team for Mageia linux when that was introduced. In
order to ensure the upgrade process was smooth, even though the kernel
supported
it, the /etc/mke2fs.conf was not turned on until after the end of support for
the older Mageia releases that did not have that kernel support for 64 bit ext4
file systems.
That way people who used a new install for the new version, could still
read/write
files in the new install while booted using the old install, including those
who
like to test a new install under virtualbox or similar before upgrading their
bare
metal install.
Trying to access a file system with the 64 bit option enabled while booted from
a kernel that did not support it would generate the errors mentioned.
