Move-Item does not work across mounts on Linux #13039
Description
Summary
Just started using PowerShell core on Linux and its fantastic so far! I can across an interesting bug regarding the Move-Item cmdlet. If I'm on the same mount point, it works as expected but if I'm moving items from one Mount to another it errors with a cross device link error.
Copy-Item is able to copy across devices as a work around. See below for details.
Hopefully this can get fixed in the 7.1 release.
Steps to reproduce
# Note: Source and destinations must be on different mounts shown by the "df" command.
$Source=/tmp/files/*
$Destination=/etc/files/
Move-Item $Source $DestinationExpected behavior
Files are removed from the source and exist at the destiation.
Actual behavior
Red Error Message:
Move-Item: Invalid cross-device link

Note that LVM is used on this system, not sure if that's causing cross-device linking issues or not.
Current Work Around
I am able to Copy-Item and then Remove-Item. This only impacts Move-Item for some reason.
Copy-Item $Source $Destination -Recurse
Remove-Item $Source
